摘要:
采用主基因 +多基因混合遗传分离分析法, 联合分析了母本干旱敏感型品种宁海晚黄豆(P 1 )、父本耐旱型品种晋豆 19(P 2 )及其杂交后代 F 1 和 F 2 四世代群体 , 研究了大豆苗期耐旱性及大豆苗期根总长 、根干重和主根长的遗传规律 ,结果显示,它们皆受 2 对主基因控制 ,且皆有多基因效应 ,其主基因效应分别表现为加性-显性-上位性效应、完全显性效应 、等显性效应和等加性效应,主基因遗传率分别为 12 .16%、45.26%、16.95 %和 19.15%, 多基因遗传率分别为 83 .54%、44.55%、72.20 %和 51 .88%。
Abstract:
T he genetic basis of drought tolerance , full root length , dry root weight and main root lengthof soybean seedling under the condition of water deficit were analyzed jointly by the P 1 , P 2 , F 1 and F 2 gen-erations derived from the cross (Ninghaiwanhuangdou x Jindou19), and mixed major genes and polygeneinheritance models of quantitative traits of joint segregation analysis of P 1 , P 2 , F 1 and F 2 were employed.The results showed that the inheritance of drought tolerance , full root length , dry root weight and mainroot length were controlled by two major genes and polygene .The two major genes showed dominant andadditive and epistatic, full dominant , equal dominant , and equal additive respectively .The heritability val-ue of major genes was 12 .16%, 45.26%, 16.95%and 19.15 %, and the heritability value of polygene was83.54%, 44.55%, 72.20 %and 51.88%respectively .
