[Method] L0527-4 was taken as male parent and Linshu 17 was taken as female parent to breed a new potato cul- tivar, so as to take advantage of the excellent characters of Linshu 17. [Result] The optimum pollination time of Linshu 17 was 10：00-12：00 am or after 04：00 pm. Spraying 10 mg/L of 2, 4-D, 50 mg/L of gibberellin or 20 mg/L of 6-BA ＋ 50 mg/L of gibberellin once every 7 days since the 3^rd day after hybridization all could im- prove the hybrid seed-setting rate of Linshu 17. [Conclusion] The hybrid seed-setting rate-improving effect of 2, 4-D sprayed on the 3^rd d after hybridization was best for Linshu 17. This study will provide technical references for other varieties to improve the hybrid seed-setting rate.展开更多
