Corvallis Sweet Corn Variety TrIal, 1974
Commercial and experimental sweet corn hy-
Research Farm on May 17, 1974.
60 pounds per acre additional N, as ammoniüm
nitrate, were applied July 12. Water was applied
-
Processing tests were made on 13 of the most
promising vane-ties. - Results of panel evaluatiors
of processed samples are shown in Table 3.
The varieties included in this trial also
were planted in a commercial field at Scio, Oregon,
for a test of head smut resistande. This test,
reported in Table 2, also included 14 varieties
not planted in the yield trial. Eight varieties
were also included in a larger trial involving
spacing variables Results are shown in Table 4
as mean of all treatments since there were no
spacing-variety interactions. One of these varieties, 70-2367 (source 2), was not included in
the remainder of the trial.

taper. Matnrity uniformity: a general estimate,
based on husked ears, of uniformity of
maturity.
The following varieties, excluding the
-
-
standard 'Jubilee', appeared to deserve special
discussion, -based on yield or other consideratiors
- Tendertrèat - good yield and-quality scores,
but quite susceptible to smut.
Mainliner - fair yield and quality, especially frozen, and fairly smut resistant.
-
COmmander - fa-ir to good yield (harvested at
74%- moistute in both -trials) , very good quality

turity.
-Stylepak fair yield, good qualIty (especially in appeaance and color, but not high in
flavor), fairly- good smut resistance.
--
NOC 243 - very high yield and very good- Smut
resistance; not processed, but appeared to be
t-ough and has a bad taper.
NCX 2004 - good yield and smut resistance,
-
but only fair quality scores, rating down on
texture-and flavor; results in previous years
-have been about the same.
NCX 2008 - good-yield and fair smut resistance; not processed but should have been;- should
be evaluated aga-in.
Rapidpak- early maturity, excellent quality
scores - highest overall score for both canning
and freezing; very good smut resistance; yield
only fair.
-Fanfare - 'yield in regular trial fair (-harvested at 74.6 moisture) ; adjusted yield in
spacing trial very good; smut resistance fairly

Taper:

about every 10 days after the early growth stages.
Vigor and uniformity of the planting were good.
Yields were usually obtained from 4 replications, with 2 replications picked on each of 2
days,but in some cases all four were picked on
the same day. The 2 extra-replIcations were used for preliminary harvests. Table 1 shows either
1 or 2 harvest dates, with days to maturity cal-

Each hybrid was
grown in six 35 foot plots, arranged in 4 randomized blocks with 15 foot guard plots on the ends
of the field. Seedlings were thinned to 35 plants
per plot.
A band application of 600 pounds of 8-24-8
fertilizer was made prior to planting and about
culated to the first.

JL 49 - a home garden variety with excellent
smut resistance.
Four additional varieties not included in
the yield test should be mentioned because of
'Sweet Sue' and
outstanding low smut readings:
NCX 2010 with 0%, NCX 2007 with 4%, and 72-1605
with 3%.
