摘  要:
选用9个自交系进行杂交试验,调查F1代各品种发芽、开花习性及株高、冠幅、花色、花径、花葶长等指标,比较其性状,分析其遗传表现。结果表明:杂交组合13×15综合性状较好,植株低矮、紧凑,冠幅大,花葶短,花径中等且花朵繁密;10×02表现较差,没有突出优点,尤其花葶较长,株形松散,观赏性差。杂交后代株高、冠幅均大于双亲,选择亲本时要注意不能选择过高的材料;花径、单株花数均介于双亲之间,单株花数更接近于多花亲本;花葶长总体表现与亲本差异不大,介于双亲之间或略大于双亲。

摘  要:
Nine inbred-lines were used to cross in this study,and F1 varieties' germination and blooming characteristics,height,crown diameter,flower color,flower diameter et al.were investigated.The results showed that main ornamental characters of cross combination 13×15 were good,while those of cross combination 10×02 were bad.In the F1 varieties,height and crown diameter were higher than that of their parents,flower diameter was intermediate,flower number was closer to the parent who has larger number,and peduncle length was similar to their parents.
