运用灰关联熵分析方法,对品种比较试验中11个以籼型温敏核不育系培矮64S为母本的籼粳亚种间杂交水稻新组合的农艺性状与小区产量的灰关联熵进行分析,得出该组合的产量与农艺性状的熵关联度,其熵关联序为:结实率>实粒数>成穗率>总粒数>有效穗>株高>穗长>千粒重>全生育期,并以此确定了以籼型温敏核不育系培矮64S为母本的籼粳亚种间杂交水稻新组合的选配及以籼型温敏核不育系培矮64S为母本的粳型恢复系的选育方向。
Using gray relational entropy analysis, the gray relation entropy of 11 agronomic traits and plot yield in indica / japonica hybrid rice with 11 indica thermo-sensitive genic male sterile lines Pei’ai 64S The entropy correlation of yield and agronomic traits of the combination was obtained. The entropy correlation order was: seed setting rate> grain number> grain yield> grain number> effective panicle> plant height> ear length> 1000-grain weight> total fertility And the new combinations of Indica-Japonica intersubspecific hybrid rice with indica thermo-sensitive genic male sterile line Peiai 64S as the female parent and the indica thermo-sensitive genic male sterile line Peiai 64S as the female parent The japonica restorer line breeding direction.
