对11个爆×普玉米组合连续进行6代自交选择,测定分析了 17个入选系51个单稳的膨爆特性。结果表明:自交选择对膨爆特性改良的效果不佳;不同爆×普组合间及同一组合不同选系间、同一选系不同单穗间的膨爆特性均存在显著差异;爆X曾遍宗测交后代产量优势明显,膨爆特性存在显著差异。同时还对爆×普后代选育方法问题进行了讨论。
A total of 11 popcorn × Popcorn hybrids were selected for 6 generations in succession, and 51 monostable popping properties of 17 selected lines were analyzed. The results showed that self-selection had a poor effect on the improvement of popping properties. There were significant differences in the popping characteristics between different combinations of the same combinations and between the different combinations of the same combinations in the same selection line. There was obvious superiority in progeny yield of Zongshen cross test, and there were significant differences in swelling and blasting characteristics. At the same time, the problems of breeding methods of populace × popularization were also discussed.
