| 摘 要： | 采用常规统计方法和加性-显性遗传模型,对8个烤烟亲本及配制的28个杂交组合的农艺性状进行了遗传分析.结果表明:(1)亲本材料与杂交组合之间,烤烟农艺性状的平均值和变异系数均存在一定的差异.杂交组合叶数和株高性状的平均值与其双亲平均值间均呈显著正相关关系,在一定程度上可用双亲均值估计F1群体性状值.(2)烤烟叶数性状主要受加性效应控制,腰叶长、腰叶宽、株高、茎围和节距主要受显性效应控制.(3)亲本P2(K326)、P3(云烟87)和P1(G80)的叶数加性效应值较高,可作为叶数性状改良的亲本.P8(红花大金元)在腰叶长、腰叶宽、株高、茎围和节距5个性状中,均表现出较高的加性效应,因而可作为亲本来改良这些性状.P6(净叶黄)的叶数、腰叶宽、株高和茎围性状均表现出较高的负向加性效应,表明该品种不宜作为这些性状改良的杂交亲本.

| Abstract: | The paper studied the heredity characteristics of agronomic characters of flue-cured tobacco.The results indicated that:(1)The average and coefficient of variation of agronomic characters had a certain difference.The correlation coefficients between average of crosses' number of leaves,plant height and parents average were significant at 5% level.so,to a certain extent,it could predicate the value of F1 population characters by using parents average.(2)Number of leaves was mainly controlled by additive effe... |
