44 Potato Variety and Seedling Screening Trials at Klamath Experiment Station, 1987 K.A. Rykbost, G. Carter, and J. Maxwell 1 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. 1/ Superintendent/Associate Professor, Associate Professor Emeritus, Experimental Biology Technician, respectively, Klamath Experiment Station.

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.

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. Table 2. Potato yield and quality of PYT-2 selections (KES), 1987.
