采用母本开花朵数标定法测定母本的异交结实数.结果表明,寻杂36制种母本始花后不同时段对父本赶粉,产量差异极显著(P<001);单穗产量变异平方和有7999%由母本开花朵数决定;以母本始花后70~85min对父本赶粉最适宜
The number of outcrossed female parent was determined by the method of flowering number of female parent. The results showed that the mothers of Xunza 36 seed were catching up with powder at different time after initial flowering, the yield difference was extremely significant (P <001); the sum of squared variation of single panicle yield was 79.99% Decided; to the mother after the initial flowering 70 ~ 85min to father the most appropriate powder
