Chipeta

Chipeta is used widely in the chipping industry and maintains good chipping quality during long-term storage. It also works great as a baked potato.

Jointly released by the Colorado and Idaho Agricultural Experimental Stations and the USDA-ARS in 1993. Has wide adaptability among irrigated growing conditions. WNC612-13 x Wiship Parentage. With a round to oval tuber shape, shallow and well distributed eyes, white to buff skin (occasional russet patches), white

flesh the Chipeta is noted for excellence. The plant stands large with an erect vine, indeterminate growth type, abundant red-purple flowers, deep and spreading root system. The yield potential is 450 to 500 cwt. Tubers are white fleshed, oval to round with white to light tan skin; eyes are shallow and well distributed; tubers consistently have high specific gravity 1.094. Plat emerges quickly; large and erect with many reddish-purple flowers; indeterminate growth habit; deep, spreading rood system that helps provide adequate water and nutrient uptake for the large vines. Competition against weeds is excellent with no major herbicide sensitivities known. Standard insect control measures generally are effective. Control of foliar early blight usually is accomplished with one fungicide application, but sometimes no fungicides are required. Tubers set in the middle of hill but later growth occurs through the hill. Rapid bulking occurs mid to late season. Tubers are resistant to hollow heart and second growth, moderately resistant to black spot and

shatter bruise. Average days from planting to vine kill are 115 to 120. Vine killing is required during most years and can be achieved relatively easily if mature. Excessive N can delay maturity and make vine kill difficult. Adequate skin set occurs within 14 to 21 days. Monitoring of tuber size is necessary after mid-August to avoid excessive oversize. Irrigation interval at the maximum ET is three days. Drought tolerance is excellent. Pre-planting generation tubers have a medium-long dormancy;both single drop or cut seed is acceptable. Germination tends to be uniform, regardless of eye location on the tuber. Avoid warming seed for more than one week at 60 F prior to cutting, to prevent excessive sprouting. Plant this cultivars 2 to 4 inches deep. Total fertilizer needs are very low compared to widely grown chipping cultivars. Excess nitrogen may delay maturity and compromise chip quality. Drought tolerance is excellent. Chipeta has

shown no herbicide sensitivities. Tubers are set in the middle of the hill, but develop throughout as the season progresses and bulking is rapid mid to late season. Monitor tubers after 90 days to avoid excessive oversize. Chipeta maintains good chipping quality during long-term storage. Tubers have medium long dormancy. Overall disease problems are minimal. Bacterial ring rot foliar symptom expression usually occurs about 65 to 70 days after planting. Excessive early N applications may delay typical leaf roll symptoms. Foliar Early Blight - moderately resistant. Verticillium Wilt - moderately resistant. Leaf roll Net Necrosis - resistant. Tuber Early Blight - moderately resistant. Silver Scurf - Unknown. Rhizoctonia Scurf - Moderate. Susceptible to Blackleg, Seed Piece decay, Leaf roll, PVY, PVX, Common Scab, Bacterial Ring Rot, Bacterial Soft Rot, Fusarium Dry Rot, Leak, and Pink Rot. Disease reaction ratings susceptible, moderately susceptible, moderate moderately resistant and resistant.
