Green Beans Tested for

Breeding green bush beans for

of Lines 4905-4911 need fu::ther evaluation, but 4911 probably will be discontinued for processing because of
inconsistent yield. Of the remainder,
only 4907 has been increased substantially and will be used in large
production trials in 1982 and 1983.
1981 yield trials, planted May 8
and June 11, included many new lines,
tested for the first or second time.
Some of these may be sent to seed
companies for initial increases but
most need further evaluation.

Muskmelons Tested at Medford
The muskmelon (cantaloupe) is one
of the important fresh market and home
garden crops in southern Oregon.
It is
a popular item in supermarkets and
fruit stands from late July until
after the first frost in October.
Quality is high because they can be
picked vine-ripe for local markets.
The crop is gaining favor for the
small-acreage farmer to fit in with
other truck crops. A wide range of
varieties is available for planting,
making the choice of the most satisfactory one an important one for the
grower.
Previous tests have identified several varieties that perform
well under the soil and climatic
conditions of the area.
Among those
are Alaska, Ambrosia, Canada Gem,
Classic, Haogen, Harper, Maiheur,
Saticoy Hybrid, Supermarket, and Supersprint.
Some of them were grown as
standards in 1981 along with several
newer entries and were evaluated from
the standpoint of home garden and
fresh market utilization.
Fourteen entries were seeded May
21 in a Central Point sandy loam soil
at the Southern Oregon Experiment
Station.
The experimental area was
fertilized with 70 N, 60 P205, 60 K20,
and 36 S (pounds per acre) during seedbed preparation.
DCPA (Dacthal) was
applied at 10 pounds per acre for weed
control June 25.
Row spacing was 72
inches with hill spacing in the row at
30 inches. Stands were satisfactory.
The first ripe fruits were picked
August 7 from Alaska, the earliest
maturing melon in the trial.
This
melon is long-oval, rather like a football in shape, and has reasonably good
quality for an early maturing type.
Data for yield, fruit size, quality
rating, and appearance are shown in
Table 1, Table 2 presents data on
seasonal distribution of yield.
Classic yielded well and was quite
early, with 45 percent of its seasonal
Earlisweet had
production in August.
fruits of good quality, but they were
smaller than others in the trial.
Early Dawn was early to mid-season in
maturity, had large fruits of good
quality, and might be considered for
commercial production in the area.
Early-Dew is a honeydew type that
produced well throughout the season.
Tam Honeydew is also of the type, but
was later-maturing and its yield was
less.
Haogen is well-adapted for production in the area.
It tends to be soft
and not a shipper, but should fit in
well for the fresh market trade. It
has a distinctive yellowish-green
stripe or speckling of the outer skin
and has a green interior which is very
sweet.
Hearts of Gold, planted as a
standard from seed obtained from a
packet on a garden seed display rack
was of poor quality, and the fruits
were slightly flattened ovals in
shape.
Another melon that was below
its usual yield and quality standard
was Malheur, a popular melon grown
locally for fresh market and in gardens.
PSX 1574 was an experimental shipping type that yielded well and was of
acceptable quality.
It warrants
further testing.
Saticoy Hybrid
produced firm, oblong fruits of good
quality.
It was grown commercially in
the area with very good results in 1981.
Star Trek and Summit were new
entries that performed well.
They
yielded nearly the same, although Star
Trek was earlier in maturity.
Both
were of good quality and were within
the proper size range for fresh market
melons.
Supermarket is the leading commercial fresh market melon in the area.
It did not quite perform up to its
usual high standard, being lower in
yield than in previous tests.
In general the quality of fruits
was high, nearly comparable to the outstanding crops of 1970 and 1977. Warm,
dry summers are conducive to good

The Effect of Soil Phos phorus Levels

Reproduction
Offshoots vs. Stumps as Planting
Materials for Globe Artichokes
Yield/plant of both stump-planted
and offshoot-planted globe artichokes
(Cynara scolymus L.) decreased as
spacing decreased, but total yield
increased. Highest yields were obtained at intermediate levels of number and spacing of shoots: 6 shoots!
location at 1.2 x 1.2 m and 3 shoots!
location at 1.2 x 0.9 m.
Early yield
of offshoot-planted artichokes was 7 x
that of stump-planted artichokes.
Production from offshoots occurs in 2
discrete periods, a moderate yield 4
months after planting and a heavy
yield during months 9 and 10. Production from stumps increased very slowly,
peaking during the last 3 months of
the experiment.

Deterioration and CO2 and Ethylene
Production of Stored Mung Bean Sprouts
The mean rate of deterioration of
green gram mung bean (Vigna radiata
(L). R. Wilcz.) sprouts stored at 0,
2.5, 5 or 10 C increased linearly with
temperature.
The sprouts reached the
lower limit of salability in about 8.5,
5.5, 4.5 and 2.5 days at the respective
temperatures.
There was no symptom of
chilling injury.
The rates of CO2
production were 23, 29, 42 and 96 mgI
kg-hr, at 0, 2.5, 5 and 10 , respectively, when measured 1 day after the
sprouts were harvested.
The corresponding rates of ethylene production were 0.15, 0.05, 0.24 and 0.90
p1/kg-hr.

Testing Methods, Variation, Morphological and Genetic Studies of Seed-Coat
Cracking in Dry Beans
Seed-coat cracking injury was
determined in Great Northern (GN) dry
bean lines in 1977, 1978 (also Pintos
in 1978) using 3 methods as follows:
9
Vogel small plot thresher (field), seed
dropping, and a controlled rotating
impact disk machine.
Differences in
susceptibility for seed-coat cracking
were observed within each testing
method. Overall, 'GN Emerson', nearisogenic determinate 'GN Nebraska #1',
and 'Pinto UI 111' had the best resistance to seed-coat cracking.
A genotype
x year interaction for seed injury
occurred with the Vogel thresher but
not with the other 2 methods. The
other 2 methods gave consistent results
but the rotating disk machine method
was preferred because of ease, rapidity
of operation and standardization of the
rotation speed.
The early and late
maturity determinate near-isogenic
lines of 'GN Nebraska #1' has less
seed-coat injury than the early and
late indeterminate lines using the
Vogel and rotating impact disk method.
The early determinate line had the
least amount of seed-coat injury for
all three methods.
'Pinto UI llP,
'Bulgarian White', and 'GN D-88',
which exhibited the best resistance to
seed-coat cracking in the 7 parent
diallel crossing study, had the most
uniform seed-coat thickness as well as
having thick seed coats.
The cultivars
which had thin or thick but nonuniformly thick seed-coats were susceptible to seed-coat cracking.
'Bulgarian White', 'Pinto UI 111', and
'GN D-88' showed high combining ability
for resistance to seed-coat cracking.
The estimates of the genetic effects
indicated that additive effects were
mainly involved.

wider spacing reduced total yield.
Pre-plant application of 168 kg N/ha
favored early yield over 112 and 224
kg/ha; however, total yield and head
weight tended to be greater with increased N.
One or two 56 kg/ha postplant applications of N increased
total yield and head size but had no
effect on early yield.
Planting interval and N treatment did not interact
significantly.

Effect of As pa ragus Plant Po Pu lation
and Plantin g Dep th on Spear Fiber
Content and Yield
'Viking' cultivar asparagus was
planted in 1978 with 1.5 m rows at 10,
20, and 30 cm depths and 23, 30, 38,
and 46 cm in-row spacings (14,600;
17,500; 21,900; and 29,200 crowns/ha).
In 1979, spears were snapped six times
over a two-week harvest period and in
1980, 15 times over a six-week period.
Spears were evaluated for fiber content early and late during the 1980
harvest period.
Early in the season, fiber content was lower than later in the season.
Later, when soil and air temperatures were higher, fiber content was
lower from the 20 and 30 cm planting
depth than from the 10 cm depth.
Fiber
content was not affected by in-row
spacing for both sample periods.
In 1979, spear number and total
yield were greater at the higher plant
population.
Yield of spears 1 cm diameter did not differ at the various
plant spacings. The 10 cm planting
depth had greater total yield and yield
of spears 1 cm diameter.
In 1980, inrow spacing did not influence spear
yield or size. The 10 cm planting
depth had more but smaller diameter
spears than deeper planting depths.
