ABSTRACT
The
selected
entries,
entries,
1987 program included a Preliminary Yield Trial of nine seedlings
at KES in 1986, the Oregon Preliminary Variety Yield Trial with 160
early and late harvested Oregon Statewide Variety Trials with 40
and an Oregon Statewide Chipping Trial with 12 entries.
In the Klamath preliminary trial two seedlings, A084130-1 and A084339-6
produced outstanding yields with good type and appearance. Twenty-six
seedlings were saved out of the PYT-2 trial, with five being considered
outstanding and worthy of advancement regardless of performance elsewhere.
These' included CO083008-1, A083037-10, A083044-9, A083196-15, and A083222-6.
Most of the twenty-six exceeded No. 1 yield of Russet Burbank by 100 cwt/acre
or more.
In the Oregon Statewide Trial, Russet Burbank ranked 32 and 35 out of
40 in early and late harvest yield of No. l's, an indication of some very
promising material in the variety development program. Russet Norkotah
ranked first in early harvest and second in late harvest and continues to
look very promising as an early tablestock selection. A74212-1 ranked
first in the late harvest in spite of stand problems. Other high yielders
included A082260-8, A082281-1, A082611-7, and A082616-18.
In the Statewide Chipping Trial none of the entries exceeded Russet
Burbank in yield, and most exhibited significantly lower specific gravity.
Two clones of Russet Burbank failed to outperform the standard seed lot.

Introduction
As an integral part of the Oregon Potato Variety Development Program the
KES participates in several aspects of the total program. In 1987 five
individual trials were conducted to evaluate seedlings at various levels in
the screening program, with more than 200 selections included in these trials.
The short season and different soils of the Klamath Basin provide a significant contrast to conditions at other locations in the total program and
therefore add an environmental stability component to the selection process.
A second major contribution to the total program involves the KES role in
storing, eye indexing and packaging for shipment all seed lots maintained in
the program. During the 1986-87 storage season more than 20 tons of seed,
representing more than 600 individual lines, were stored at KES. During
January in excess of 8,800 individual tubers were eye-indexed and delivered
to Corvallis for disease testing. Prior to the planting season lines were
individually packaged for redistribution to 10 locations in seven states.
A third component involves the evaluation of cultural management practices
for optimizing production of promising material in the various regional
programs, as well as new releases from any North American breeding program
that may be of interest in the Northwest or in the Klamath Basin. In 1987 one
experiment was conducted to evaluate seed spacing response of the standard
varieties Russet Burbank and Norgold and new or near releases Krantz, Russet
Norkotah, and A74212-1. A second trial assessed the fertilizer response in
Russet Burbank, Norgold, Russet Norkotah, and Shepody. As the Oregon program
approaches maturity and numbers of advanced materials increase, a major
expansion of this activity will be required.
This report will consider only the variety screening aspects. Although
the seed storage, eye indexing, and seed lot packaging role involves a very
significant portion of the KES workload in mid-winter, it is not a research
function. For 1988 and beyond the COAES will assume this role in the statewide program.
Procedures
All variety screening trials used a randomized complete block design. In
all but one trial 15 plants with four replications were grown. The PYT-2
trial included 12 plants per plot and three replications. Seed spacing was 12
inches in 32-inch rows. Fertilizer for all trials included 850 lbs/acre of
16-20-0 banded at planting and 100 lbs/N acre as solution 32 sprayed on in
combination with 3.5 lbs ai/acre of Eptam on June 3. Additionally, Metribuzin
was applied aerially at 0.5 lb ai/acre on July 1.
All trial areas were treated with Telone II at 20 gpa shanked in on April
20. Temik at 3 lbs ai/acre was banded at planting and Monitor was applied
aerially at 0.75 lb ai/acre on July 24. Fungicide treatments included Captan
seedpiece treatment at 1 lb/100 lbs of cut seed and Ridomil MZ applied
aerially at 2.0 lbs/acre on July 24.
46
Irrigation was applied with 40 foot x 40 foot solid set sprinklers twice
weekly from early June through the first week of September at a schedule to
replace 90 percent of pan evaporation. Total water applied for the season
included 15.75 inches of irrigation and 2.54 inches of precipitation.
Planting dates, vine desiccation and harvest dates will he discussed
individually by experiment. In all but the PYT-2, potatoes were harvested
with a one-row digger-bagger and all tubers from each plot were saved, stored,
and graded in early November. Specific gravity was determined on 10-pound
samples of 6- to 10-ounce size from the No. 1 grade where possible, by the
weight-in-air weight-in-water method.
Results and Discussion
Klamath PYT-2
Selections that looked outstanding in 1986 four-hill plots at KES, but
were not saved at other locations in the state, were included in this experiment with Russet Burbank as the standard. The trial was planted on May 20,
desiccated with Diquat at 2 pts/acre on September 22 and harvested on October
2. Two seedlings produced significantly higher No. 1 yields than Russet
Burbank (Table 1). A084130-1 had a good size distribution, very attractive
appearance, and solids nearly the same as Russet Burbank. A084339-6 produced
the highest yield but size was excessive, greening was a problem, and solids
were low. This entry would probably perform much better at a closer seed
spacing. Of the nine entries included, only these two should be advanced for
further evaluations.
Oregon Statewide PYT-2
Potatoes were planted on May 20. Vines were rolled on September 18,
sprayed with Diquat at 2 pts/acre on September 22 and rotobeat on October 8.
Harvesting occurred on October 13 and 14. All plots were dug with a one-row
digger and left in place for selection. Only the attractive looking lots were
selected. Russet Burbank was used as a filler to replace two seedlings not
available at planting. A total of five Russet Burbank plots were selected.
Lemhi was selected in two replications, and Norgold in one. Entries C00821773, C0083008-1, A083148-1, and A083218-10 were saved from each replication. A
total of 15 entries were saved from two replications, and an additional 36
entries were picked up in only one replication.
47
A summary of the performance of Russet Burbank and the 26 best entries is
presented in Table 2. Statistical analyses were not performed. An
overall rating is indicated based on yield, solids, tuber type and other
considerations. C0083008-1, A083037-10, A083196-15, and A083222-6 are
considered worthy of further evaluation at KES whether or not there is
interest at any other statewide locations. An additional eight entries
showed outstanding performance in at least one aspect, while the remaining
13 had at least one major weakness that may be sufficient to drop them from
further consideration.

Oregon Statewide Advanced Trials
Two identical experiments were planted on May 19 with standard
varieties Russet Burbank, Lemhi and Norgold, a local clone of Russet
Burbank, the named variety HiLite and 35 advanced seedlings from the Oregon
program. The early season trial had vines rolled and sprayed with Diquat at
2 pts/acre on August 31 and vines shredded with a rotobeater on September 9.
The full season trial had vines rolled on September 18 and shredded with a
rotobeater on September 21. The trials were harvested with the one-row
digger-bagger on September 30 and October 7, respectively.
The two outstanding selections in terms of No. 1 yields were Russet
Norkotah, which ranked first in the early harvest and second in the late
harvest, and A74212-1, which ranked ninth and first, respectively (Tables 3,
4, and 5). Both lines exhibited low solids but were good in all other
respects. Russet Norkotah had excellent appearance and type except for a
slight tendency for tapering on the stem end. The A74212-I was a little
rougher in appearance. Other seedlings with superior performance included
A082260-8, A082281-1, A082611-7, and A082616-18. The local clone of Russet
Burbank obtained from Carl Rajnus produced a significantly higher No. 1
yield at late harvest than did the standard clone and ranked third in yield
of No: l's. This suggests the need to look at clones or seed lots of Russet
Burbank in more detail.
Oregon Statewide Chipping Trial
Potatoes were planted on May 22, topkilled with Diquat on September 22
and harvested on October 2. While low yields were observed for Yellow Fin,
#12567, and DB-1 entries, no outstanding performance was noted (Table 6).
Norchip produced a good yield at a spacing that is too wide for this
variety. All entries exhibited solids that would be barely acceptable for
chipping stock. A better selection of material is needed for this trial and
the seed spacing should be changed to obtain optimum performance of Norchip
and Kennebec, the industry standards. Atlantic, a leading chipping variety,
should also be included as a standard variety in future trials. Processing
quality data will be obtained at a later date from samples submitted to
Corvallis.
Sunnary
A relatively large number of promising seedlings are in the Oregon
Potato Variety Development Program. A comparison of the performance at KES
with that at other stations shows that while some of the outstanding
selections at KES also do well at other sites, cases also exist where
excellent performance at KES is unique. This emphasizes the need to
maintain an active role in the program at KES.
49
In future trials several procedural changes will be made to improve
data quality. At advanced levels larger plot size will be implemented to
improve precision. The need for early and late harvest of the Oregon
Statewide Trial is questionable. Larger plots at this stage will be more
beneficial. KES should be included as a site for the Western Regional Trial
of advanced material that is close to official release. Additional
varieties recently released from other breeding programs also need to be
evaluated at some stage to provide local growers with advance information on
performance of these varieties under local conditions. Current examples of
this need are Krantz, Shepody, and Yukon Gold, all of which are of increasing interest in Oregon.
