马铃薯13个品种(系)杂交亲和力及F1代性状研究
Study on the Hybridization Affinity and F1 Trait Analysis of 13 Potato Varieties
摘要
Abstract
In this study,13 potato varieties(lines)were used as parent materials for hybridization experiments through artificial pollination.The fruit setting rate and seed number of different hybrid combinations,and some agronomic and yield traits of F1 seedlings from different hy-brid combinations were analyzed to investigate the effects of parental selection and early-generation trait screening on the efficiency of potato breeding.The results showed that there were significant differences in the average fruit setting rate,average seed number per fruit,and aver-age seed number per flower among different parental hybridization combinations.The average fruit setting rate and average seed number per fruit jointly affected the average seed number per flower,which ultimately affected the number of harvested seeds.The number of tubers per plant had stronger genetic stability in the early generation of potatoes,so more attention should be paid to the selection of this trait in early-gen-eration breeding.关键词
