摘要
[目的]探索提高马铃薯品种临署17号杂交结实率的方法。[方法]以L0527－4为父本，以临薯17号为母本配制杂交组合，以期运用临薯17号的优良性状。[结果]]临薯17号的最佳授粉时间为上午10：00～12：00或下午4：00之后，杂交后第3天，喷施10 mg／L的2，4－D、50 mg／L的赤霉素、20 mg／L的6－BA＋50 mg／L赤霉素在马铃薯孕蕾期间，每隔7 d喷洒植株，这3种处理方法均可提高临薯17号的杂交结实率。[结论]杂交后第3天喷施10 mg／L的2，4－D提高临署17号杂交结实率效果最优。该研究可为其他材料提高杂交结实率提供技术借鉴。
Abstract
Abtsract [Objective] To explore methods for increasing the hybridization seed setting rate of Linshu 17 potato.[Methods] L0527-4 was taken as paternal plant, and Linshu 17 potato was used as maternal plant to hybridize new potato variety , so as to apply excellent traits of Lin-shu 17 potato variety.[Results] The best time of pollination was from 10 am to 12 am, or after 4 pm.Spraying 10 mg/L 2,4-D gibberellin in the third days after hybridization or 50 mg/L GA gibberellin or 20 mg/L 6-BA+50 mg/L GA gibberellin every 7 days.These three treatment methods can increase the seed setting rate of Linshu 17 hybridization.[Conclusion] In the three methods, spraying 10 mg/L 2,4-D gibberellin in the third days has the optimal effect of increasing the hybridization seed setting rate of Linshu 17.Thus, this study is expected to provide reference for other materials for increasing the hybridization seed setting rate .
