| 摘 要： | 利用抗黄萎病棉花种间渐渗系冀79作父本,高感病陆地棉品系1096作母本,配制杂交组合。感病对照、亲本及F1、F2在田间混生病圃鉴定。对亲本、F1及F2分离群体的抗性表现进行调查、统计,分析该抗源抗黄萎病性状的遗传方式,结果表明,该抗源抗性是由1个显性抗(耐)病基因和2个加性基因共同起作用,其中加性基因起主要作用。并且2个加性基因是独立遗传的,当2个加性基因同时存在并且纯合时,植株表现为高抗;当2个加性基因同时存在并且杂合时,植株表现为抗病;当只有1个加性基因存在时,不论纯合还是杂合,植株都表现为耐病;当2个加性基因不存在时,植株表现为感病。

| Abstract: | Crossed between the susceptible G.hirsutum self-line 1096 and the resistant introgressed line Ji79 that derived from interspecific hybridization,then identified the diseases resistance of susceptible CK cultivar,parents,F1 generation and F2 generation in the Verticillium dahliae nursery.Investigation and statistic of the resistant performance of the parents,F1 generation and F2 generation were used for analyses on the inheritance of Verticillium wilt resistance of this germplasm resource.The results showed ... |
