Introduction and Evaluation on High-Generation Hybrid Potato Strains

For breeding or introducing new high-quality, high-yield potato varieties for cultivation in Fujian, 12 high-generation progenies of potato strains from the germplasm collection of Institute of Vegetables and Flowers, Chinese Academy of Agricultural Sciences were evaluated in November, 2016. Among them, N182, D597, D862, N157, N209 and N215 had a yield 7% higher than the control variety, Zihua851, and were selected for further evaluation. In the multipoint experiments in the following year, N182, D597 and D862 showed a tuber yield 50% higher than the control. The potatoes of N182, N157 and D597 excelled in their nutritional qualities:N182 was high on vitamin C at 27.1 mg·hg^-1, N157 on potassium at 2.94 g·hg^-1, and D597 on methionine at 0.12 g·hg^-1, on valerian at 0.51 g·hg^-1, on isoleucine 0.35 g·hg^-1, on phenylalanine at 0.46 g·hg^-1, on histidine at 0.16 g·hg^-1, on serine at 0.42 g·hg^-1, on glycine at 0.37 g·hg^-1, and on cysteine at 0.09 g·hg^-1.
