Additional data uhioh are important enough to include as a orator of permanent record are included in an appendix at the end of the report.
Knee lame of the line projects are eomducted eeope personnel located at Oregon State College, more than one investigator may have work reported in one line project report. An attempt hap been made to give each investigator full credit for his contribution to the year's work.
The work reported in this report is directed along five lines involving studies on hop culture, breeding, disease and quality investigations.
The studies on hop culture and breeding are cooperative among the agronomist, the chemist and the plant pathologist. The studies on disease control are
Chemical studies are 000perative between conducted by the plant pathologist the Chemist and the agronomist on certain phases, and other phases are con.
ducted independently by the Chemist.
A fifth type of investigation inoludes studies of field, greenhouse and laboratory techniques relative to the breeding, disease and agronomic lines of endeavor. Any OM of the project leaders may have work reported under this line project from time to time.
In addition to the support given to this work by public agencies, certain annual grants of funds have been contributed by the Brewing
Industries
Research Institute for partial support of the work in Oregon. Begiming in
1959, such support will come from the United Brewers Foundation instead,

On February 5, 1959 it will present current research findings to the Bop Growers of America, Inc. at their annual convention.
Bop production traditionally has been subject to wide variation in total acreage, total producrtion and center of production.
The hop industry suffered a severe recession in the early 19504 due to low prices.
Since 1956 there has been considerable improvement in this situationl and the industry is ones again on a sound basis. A oontinuation of expansion could however,

Genetic diversity for the breeding program consixte four widely grown varieties and approximately 75 introductions of which only a few remain.
Many of them are new represented only by first or later generation progenn and some have been discarded entirely.
gone of the varieties or introductions have exhibited immerity to downy mildew.
Some of them possess acceptable quality and agronomic characteristics, but none of them are sufficiently satisfactory in all important features that improvement through breeding is not desirable.
Due to resent reports from Wye College in England that varieties of
American parentage exhibit resistant to downy mildew crown infection, a now approach was initiated into the breeding program.
C. E. Horner collected living specimen* of the wild hop native to Utah last spring.
Clones of these plants were established in the breeding block and will be used as breeding MRS terial in future years.
Accession numbers will be assigned to the clones when it has been determined haw many of them will live.
Since its inception, the hop breeding program has been confined generally to inter varietal crossing involving both domestic and foreign varieties.
A modified recurrent selection scheme has been in effect since 191s8.
Selection has been based upon resistance to disease, primarily downy mildew,

The growing season at Corvallis was unusaally hot in 1958 and was particularly hard to the breeding pi ogrwa Maar of the foils flowering branches were blasted or otherwise kondered non-functional under the parchment bags. As a result only about 15% of the crosses mods produced seed.
This is about one.third as many as are good in the average year.
Group Is 54 crosses were attempted among resistant and susceptible male and female plants in order to obtain seedling progenies on the crosses used in a downy mildew inheritance study set out last year.
Only sight of these crosses set seed, and the whole group will be re-made in 1959.
It will be desirable to have seedling reaction on these progenies as well as mature plant reaction.
Group III Six (grosses were repeated (25 attempted) involving parents that had produced downy mildew resistant seedlings several of which had gone into the 1957 nursery or elss bad had an insufficient progeny test in 1957,
These crosses were the same as the Group II crosses in 1957. They were 58001, 58010
58012, 58034, 58053 and 58057.
Group ITIs 16 crosses were made (104 attempted) between female plants which had produced several resistant seedlings each from open-pollination in 1956 and 1957 and males which had resistant progsrq in either 1956 or 1957. These crosses wore,

The plots were three hills spaced four feet apart in rows eight feet apart.
One plot of each parent and four plots of each cross were included in each of the three replications.
The main purpose of the triple lattice design was to insure that the plots of each cross were separated as well as possible with respect to each other. This also insures that no parent occurs In the same 1a -plot block more than one time with any other pare
It is believed that this will give mere realistic estimates of genetic and environmental variance when the area occupied by the experiment is taken into consideration.
The variance of the parents will be used to estimate environmental variation.
The triple lattice design is, therefore, mostly for the purpose of field arrangement rather than for statistical analysis.

1958 as in previous tests cited above.
Pro
Seed from the 1957 crosses was germinated and seedlings planted by
S. N. Brooks. When seedlings were 10-12 nooks old they were heavily inoculated with downy mildew.
Inoeulma consisted of sporangia collected from several varieties and lines to include possible different races of downy mildew, although the existence of races has never been demonstrated tor suspensions of downy mildew spores were prepared by washing infected 'spikes" then filtering to remove the larger particles of soil and plant debris.
Inoculation was accomplished by spraying 20 ml.
of a uniform spore suspension on the undersides of the leaves of seedlings in each flat.
Humid conditions were maintained by covering the inoculated seedlings with cheesecloth saturated frequently with water,
Good infection was obtained and disease developsent was rapid and vere.
Seleotions for resistant plants were made with the assistance of
S. N. Brooks.
The number of seedlings from each cross was recorded.
A record was made of the number of ',atomically infeoted seedlings in each cross, and each cross was rated for mildew severity on a scale of 0 to 3 representing none, light, moderate and severe infection.
Selection of plants to be saved was based on both mildew resistance and seedling vigor and appearance.

It is hoped that sufficient data will b obtained during the 1958 and 1959 seasons.
Reasons fo k: asters in o before a breeding pro efficiently. Evaluation of male breeding vales has largely been a matter of progeny testing which is time consuming and laborious.
Often times progeny testing has been incidental to the breeding program with the result that incomplete information is available, Methods are needed to evaluate maim; phenotypically, particularly for quality and yield, if possible, to aid in selecting breeding material.
Mature and extent of evious
The most valuable work along this line has been done in England.
Wormald (J. Agr. Res., 1915) presented a detailed comparison of the variation existing in American and English male hops for floral leaf and vine characteristics.
His paper was largely descriptive having limited data.
No attempt was made to separate genotypic from environmental variation.
Ehara (J. Fac.

20 male lines were planted in a replicated trial of 5 rooliootione of single hill plots in 1956.
The five replications were made by vegetative propagation at the 20 lines and would be expected to be genetically alike in the year that they were planted. These lines were net selected for any particular characteristic, except that one was selected because of extreme earliness, and would be expected to represent a random sample of the male genotypes available at Corvallis.
17 different pedigrees are represented in the group.
Observations were made on the male lines for flowering behavior and branching pattern in the field.
Male flower samples were obtained by bagging the sidearms in parchment bags for 3-4 days while the flowers were shedding pollen. At the end of this time the flowers which had completed their pollen shedding and had abcissed were removed in the bags. They were then dried at low temperature in vacuum and frosen. These samples provided the material for

This trial is concluded with this summary of the results for 1958 s years.
The 29 entries were planted getative clonal material in plots replicated five times in a randomised block design.
The 27 experimental lines represented a group of selections which made in 1950 Out of crosses made in 1949.
Although most of them were intermediate in maturity there was considerable range for this charaeter tram medium early to late (later than in Late austere)
The trial has been grown under irrigation and has received Eras two to four irrigations per season.
Applications of 111, P, and E fertilisers have been made every year either by ringing the hills or by broadcast application.
Attempts have been made to control insect and disease pests.
The overall cultural program on this trial has been carried out in a manner consistent with good management practices.

There were also in 1958 t at harvest time such differences are a reflection of since known early lines are usually drier at a common date than known late lines.
It is unfortunate that a satisfactory picking machine is not available at Corvallis with which each line in a trial could be harvested at its maturity rather than at the average maturity of all lines in the trial.
Such a machine would be of great value but it would be very difficult and costly to develop.
14 mean yield groups were separated in a five.year
rlr of o replications using BuncanIs YAM Is Range Test.
This analysis indicated that rather marked differences among the 29 lines were present during the five.
year study.
The highest yielding lines 112 -I, which, incidentally, is current ly undergoing advanced testing, produced significantly more hops than 23 of the
Fuggles the lowest yielder in the test, produced significantly less than all of the other lines except for 144-1 which have been selected for off - station testing,

1955.

A moderate amount of downy mildew in 1957 is hardly enough to account for the low yield of this variety in 1958.
Seven of the lines outyieldsd Late Clusters in 1958, some of them utuggles" types.
Three of the varieties have outyieldsd Late Clusters over the three year period.
These are 1074, 112-1 and 123 -1.
At Prosser significant differences were indicated for both 1957 and 1958.
Late Clusters was the highest yielding variety each year, and on the basis of the LSD's exceeded the yields of 11 varieties in 1957 and all of the others in the trial in 1958.
These results indicate rather conclusively that observation plots should be established at Prosser from which to select lines for testing in that area. This could be done easily by planting the selections at Prosser which have been screened only for downy mildew reacti ©n at Corvallis*
It is apparent from these trials that considerably more relative vriability is present at Corvallis (CV of 16% in 1958).
There was room for only three replications to be planted at Corvallis in 1955, whereas five were planted at Prosser.
In future years, particularly for "advanced" yield tests less than five replications should not be considered.
Three replications may be sufficient for preliminary testing, however, if space is at a premium.
The alpha-acid and oil data are in line with last year's results.
Alphasiaoid and oil contents at Prosser were noticeably low for the second year.

Two applications were made.
The first application was made
May 3 and 4 when new shoots arising from the pruned crowns were about 8 inches long.
The eeoond, was made May 26 and 27 about one week after the first vine training. Data on number of systemically infected shoots present were taken

The pattern of absorption and tranelocation of streptomyoin by hops receiving a single spray of 1000 ppm showed a maximum absorption of 46 pia after 24 hours followed by gradual reduction over a period of 15 days.
to greenhouse tests conducted previously (1956 report p. 61) maximum absorption was the same, but field-grown hops retained detectible quantities of streptomyein fora much longer period.
Following a second application of 1000 ppm stroptmaysin 21 days after the first application, the maximum level of streptomycin absorbed was much higher than after a single application on either field or greenhouse grown plants.
This effect oould be due to age of shoots treated, effect of environment on absorption, or afflict of a previous application of streptomycin.

It be renenbered at thin point that yields in general in 1958 were mach lower than in the previous two years.
There was only a 27% &moose in yield whore basal growth was allowed to remain in 1957 as compared to a demos's* of 31-60% where basal growth was moved periodically in 1957.
Although those results indicated that complete stripping suckering have pronounced detrimental effects on vigor the following year, it is felt that this operation should still be carried out early in the season to avoid or control 80/92e disease and insect infestations.
This study points out that the translocation of food materials from the basal growth to the roots in the fall should be studied more thoroughly.

Since gibbereilic acid has such pronounced effects on other species of plants was decided to try it on hops.
Nature and extent of POOViOna work:
None on hops.
Good accounts of this material and its use on other plants are given in ARS Special Report,
ARS 22-47, 1958 and a technical bulletin,
"fibre", published by Merck and Go. Inc. of New jersey.
Procedure
A trial was laid out with four replications of 1 a 5 hill plots, with n a randomised block design.
Two concentrations of gibbersllic acid in water solution were applied at three different stages ©f growth.
Each ion was applied when the hope wore about five feet high, when they were about 10 feet high, and when they were just coming into flower.
Each plot received a treatment only once.
The spray treatments were applied at low pressure (5-7 psi) in order to minimise drift.
The first treatment was applied on June 11, at which time the hop vines and leaves were wetted until the spray dripped from most of the vegetation.
The later two applications on June 19 and July 2$ were not as thorough, and spraying was done only until most of the vegetation had received some of the spray.

Fairly wide ranges apparent* however.

The most striking aspects of this study were the decrease in cons die delay in flowering time caused by the earliest application of the acid* particularly the 500 ppm rate.
Following treatment on June 11 there was considerable succulent spindly growth apparent a few days later.
By
June 25, hot weather had blasted most of the sidearm tips and the flower buds which had just formed.
Later there was a profuse amount of vegetation, particularly high-up on the plants.
it is believed that much of the flower development on this treatment resulted from a esscend" blooming which accounts for the delay.
It appeared that most of the inflorescences developed into cones causing a much higher count to be present than on the check plots* but these wore greatly reduced in size at maturtV
It is interesting to note that late treatment with gibb acid caused a reduction in alpha -acid content.
As a general rule alpha-acid content is not influenced too greatly by treatments which affect the vigor of the plants, however, such results apply to material whose action is of a different nature.
There were no apparent differences in maturity, supported by the fact that the hops did not differ in moisture content at harvest time.
As a general rule, moisture content of the hops is closely associated with maturity.. within a given season for a particular variety.

These were ussd for preliminary work to establish procedures and provide a basis for planning sample collections during 1958.
It was felt that the plant juices in the hop cones would provide easily obtainable test speoinan and at the same time be very likely to respond to maturity changes. At the same time it was expected that the amt of plant Jules present would be a function of maturity since the total moisture present drops with aging.
Procedure for testing 1957 sample's'
The frozen sample was thawed and weighed.
It was pressed in a
Carver hydraulic press and the first 5 ills of juice to appear was collected.
The pressure was raised to 1000 posoi. and all juice that was freed was collected.
The pressure vas then increased to 6000 posoi and the remainder of the juice was collected.
Nearly all the expressable moisture was obtained at 1000 posit The pressed pad was weighed and the expressable moisture calculated.
Samples of the expressed were evaluated for refractive index,

In conjunction with the previous recovery of oC ...acid and (-.3 -acid absorbency, it was concluded that the loss of absorbency from the methanol extracts was not because of a loss of oC - or (-3 -.acids.
Treatment of resins from columns showing a low A 332 recovery with strong H Cl failed to remove any A 332 absorbing material indicating that this residue is extremely tightly bound to the resin or trapped physically within its molecular structure.

A minimum of lop hills of each riety will be rem red in o sufficient hops will be available for large-scale brewing trials.
Planting stock of these varieties will be provided by the Collage under a mismoraNhalof understanding between the grower and the college.
3.
Fieldiplot diagrams
The locations of the varieties in a trial will be deterrined at random.
The plets will consist of single roue grown side by side with each series of the fire varieties being located adjacent to another series or replication.
The planting of border or guard rows will be permitted around the entire experimental area.
Guard rows may also be grown between the replications, but not within replications.

b.
Quality will be determined by laboratory analysis of the samples provided on an individual plot basis and by brewing trials.
Baled lots of each variety will be provided fray one, too, or three trials each year Shich will be submitted for brewing trial analysis.
c.
Disease reaction will be determined by observation throughout each season in conjunction with more detailed studies at the college do Picking ability be determined by observations on shattering, leaf and stem content, and ease of picking at the time the plots are picked by oommercial equipment.

Committee.
WS believe that the Committee will serve a very useful function and are pleased to approve the appointments of Mr. Stanley Brooks as representative for the U. S. Department of Agriculture and Dr. Chester

For the Committee to accomplish the work of evaluating research results end preparing information for release to growers we agree that meetings should be held not lees than two and not more than three times each year.
Your organisation has taken, a mast progressive step in sponsoring the organization of a National Hop Research Committee.
The purpose of all State and Federal research on agricultural problems is to reduce production hazards, increase efficiency of crop production, and improve the quality and farm value of crops produced.
The job is not finished until research result3 are tads available to growers.
It is our hope that the new Committee will function effectively in helping to bridge the gap between research workers and growers.
