芝麻有限与无限开花习性的遗传关系及其性状差异的初步研究

用“0 ]-82 31 -1”等有限开花习性芝麻材料与普通无限开花型芝麻“赣芝 3号”配制正、反交组合 ,研究了芝麻有限与无限开花习性的遗传关系 ,并分析了有限与无限开花型芝麻主要性状间的差异。结果表明 :有限与无限开花习性之间存在复杂的显、隐性的遗传关系 ,有限开花型芝麻在千粒重、抗病性等方面优于无限开花型芝麻

Preliminary Study on Genetic Relationship between Determinate and Indeterminate Flowering Sesame and Their Difference of Main Characters

By means of reciprocal cross between indeterminate flowering sesame variety “Ganzhi 3” and determinate flowering sesame materals “0]-8231-1” and so on, the genetic relationship between determinate and indeterminate flowering sesame was studied, and their differences of main characters were analysed. The results indicate that there is a complicated dominant and recessive genetic relationship between determinate and indeterminate flowering habit, determinate flowering sesame possesses higher kilo-grain weight, stronger disease resistance and so on than indeterminate flowering sesame.
