Abstract:

为了明确2个小麦抗赤霉病侵入的主效QTLFhb4和Fhb5的抗性遗传和互作模式,采用土表法并结合扬花期喷洒孢子液接种,以病小穗率(PDS)为鉴定指标,对携带Fhb4和Fhb5的不同遗传背景的BC3F1、BC3F2以及抗感对照进行了抗赤霉病侵入的表型鉴定和评价。结果表明,Fhb4和Fhb5在温麦6号和周麦22这2个不同的遗传背景中,PDS表现出杂合基因型和供体亲本望水白基因型的差异不显著,而与轮回亲本基因型之间的差异达到显著水平,抗感分离比经卡方检验符合9:3:3:1的分离比例,其抗性遗传遵循2个独立的遗传因子控制的显性遗传模式;同时,Fhb4和Fhb5抗侵入性效应相当,它们之间存在加性效应,二者累加后的病小穗率显著低于单个Fhb4或Fhb5。因此,在育种实践中对这2个抗赤霉病显性基因的聚合利用将有助于提高育种材料的基础抗性。
