- 摘要:
- 利用高抗烟粉虱种质滑皮豆和高感种质齐黄26,组配滑皮豆×齐黄26杂交组合,分别在山东济南、冠县构建了F1、F2∶3遗传群体,调查亲本、F1群体和F2∶3群体各个家系单叶感染烟粉虱的平均数,采用植物数量性状主基因+多基因混合遗传分离分析方法,分析各遗传群体抗烟粉虱的遗传模式。结果表明:大豆对烟粉虱抗性的遗传符合一对主基因+多基因的混合遗传模式,主基因的遗传率较高,分别为61.86%和97.43%;多基因的遗传率较低,分别为23.76%和0.88%;而且不同地点的主基因和多基因遗传率差异较大。说明大豆抗烟粉虱既受主基因控制,又存在多基因效应,同时受环境因素影响。改良大豆品种对烟粉虱的抗性应重点利用主基因,同时兼顾多基因的积累。
- Abstract:
- Whitefly(Bemisia tabaci Genn)is one kind of agricultural pests with wide occurrence,severe harm,strong virulence in soybean around the world,and it is an effective way to breed resistant soybean varieties to control whitefly.The objective of this study was to reveal the inheritance of resistance to whitefly in soybean,and provide information for soybean breeding.The cross between Huapidou,a highly resistant variety and Qihuang 26,a highly susceptible variety,was made.F1and F2:3 populations were derived from this cross in Jinan and Guanxian.The mean of whitefly per leaflet(MWPL)of all the populations was identified.Genetic analysis was performed under the major gene + polygene mixed inheritance model in these populations.The results suggested that resistance of soybean to whitefly was controlled by one major gene and polygene,with the major gene inheritability of 61.86% and 97.43%,and polygene heritability of 23.76% and 0.88%,respectively,and the inheritance was affected by environment.
