High - yielding, high - starch potato new lines 90 - 10 - 5 8- 1 Introduced by Tianshui Institute of Agricultural Sciences potato breeding group in 1998 from Zhuanglang County Agricultural Technology Extension Center. In Tianshui City potato area test from 1999 to 2000, the average yield of 2 10 times (times) at 2 a was 2 5 94 6 .3 kg / hm 2, which was 190 0 0. 5 kg / hm 2 more than that of the control 36.6%. The strain is highly resistant to mosaic virus disease and ring rot, moderately resistant to late blight; growth stage 138d, late maturity; potato block round, shallow eyes, tubers focus; tubers containing starch 18.0 1%, Vc 16 .8mg / 10 0 g, crude protein 2.56%, reducing sugar 0.27%. It is suitable for planting in the areas of Er Yin Shan and alpine wet areas of Tianshui at an elevation of 160 ~ 2200 m
