| 摘 要： | 本文通过对马铃薯品种及种间杂种实生苗群体12个数量性状的遗传相关分析,确定了影响杂种群体产量的重要因子,在对其遗传参数进行分析的基础上,深入探讨了优质高产实生种的综合选择指数,并分析了马铃薯普通栽培种(S.tuberosum)和新型栽培种(Neo-Tuberosum)综合指数选择的亲本效应及各类组合的遗传结果,提出了获得优质高产组合的选配方案及其选择途径.

| Abstract: | In thes paper,the important factors that affected hybrid population's yield were determined by the analysis of genetic correlation among 12 quantitative characters in the potato seedling populations of intervarietal and intervarietal and interspecific hybrid.After analysed their genetic parameters,exhaustive studies had been made on the comprehensive selection indexes of the population for good good quality and high yield.The parents effect of S.tuberosum and Neo-tuberosum and the genetic results of various combination types were also analysed for comprehensive index selection.Finally the scheme of hybridization and selection were put forward to get ggd quali()v and high yield potato combinations. |
