- 摘要:
- 优良玉米自交系的选育与应用以及杂优模式的利用是选育新品种的关键,以黑龙江省核心玉米自交系作母本,选用含有国外血缘、综合性状优异的自交系作父本,杂交育成了集高产、优质、综合性状优异、出籽率高、活秆成熟等于一体的玉米新品种——龙育4号。
- Abstract:
- The key to breed new maize variety is breeding and utilization of good maize inbred lines and utilization of heterosis model.We crossed core maize inbred lines in Heilongjiang as female parent and integration good characters line abroad as male parent.By directed breeding the new maize variety with high yield,good quality,integration good characters,shelling percentage and green plant was derived.The success of breeding Longyu No.4 showed that improvement and utilization of core maize resources in Heilongjiang and maize abroad was the key to breakout of maize breeding in Heilongjiang province.
