摘要
以13个马铃薯品种(系)作为亲本材料,通过人工授粉的方式进行杂交试验,对不同杂交组合的坐果率、种子粒数等以及F_(1)代实生苗的部分农艺和产量性状进行了分析,以探究亲本选择与早代性状筛选对马铃薯杂交育种效率的影响。结果表明,不同亲本杂交组合的平均坐果率、平均每果种子粒数和平均每花种子粒数存在显著差异,不同杂交组合间平均坐果率与平均每果种子粒数二者共同影响平均每花种子粒数,最终影响收获的种子数;单株块茎数在马铃薯早代中遗传稳定性更强,因此在早代选育中应更加注重该性状的选择。
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 F_(1) seedlings from different hybrid 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 average 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-generation breeding.
