摘要
利用高抗除草剂2,4-D的亲本与不抗除草剂的品系配制组合,对亲本、F1和F2植株进行抗性鉴定、调查、统计,进行棉花抗除草剂2,4-D性状遗传分析,结果表明,棉花除草剂2,4-D抗性性状是由一对显性基因控制。该抗除草剂性状属于质量性状遗传,便于在棉花育种中利用,抗性水平较高,能达到800mg/kg以上水平。抗除草剂性状可以在棉花常规育种和杂交种生产利用中发挥作用。
Crossed between the G.hirsutum line Ji155 that was susceptible to herbicide and the high resistant selfing line K24-D,then identified the herbicide resistance of parents,F 1 generation and F2 generation in the field. Investigation and statistic of the resistant performance of the parents,F 1 generation and F2 generation were used for analyses on the inheritance of herbicide resistance of this germplasm resource.The results showed that herbicide resistance was controlled by a dominant gene.This resistant trait belongs to the quality genetic,so it is easy to be used for cotton breeding.And it is high resistance level that reach to 800 mg/kg 2,4-Dichlorophenoxy acetic acid.Antiherbicide trait exhibited important utilization value to cotton breeding and hybrid cotton production.
