Abstract:

从83份黄淮海地区代表性材料中按根系类型选取28份,在苗期以株高、叶龄、根干重和茎叶干重隶属函数的平均值为指标进行2年耐旱性重复鉴定,从中筛选出晋豆14强耐旱型材料。比根干重、比总根长、比根体积与耐旱隶属函数值均呈极显著正相关,可作为耐旱性的根系性状指标。利用“科丰1号×南农1138-2”衍生的RIL群体为材料,对耐旱相关根系性状采用主基因+多基因混合遗传模型分离分析法进行遗传分析。结果表明,该两亲本间比根干重、比总根长、比根体积的遗传均为两对主基因加多基因模型,后两者主基因间有连锁(重组率4.30%,1.93%);主基因遗传率为62.26%~91.81%%,多基因遗传率为2.99%~24.75%;耐旱相关根系性状各主要由1对主基因控制,另1对效应较小,3个性状的改良均着重在主基因加性效应。
