主茎高等农艺性状是影响花生株型的主要植物学性状,与花生产量密切相关。为培育高产花生新品种提供遗传信息,本研究以远杂9102/皖花4号 F2群体为材料,利用主基因+多基因混合遗传模型对花生主茎高、侧枝长、分枝数和结果枝数4个性状进行遗传分析。结果表明,4个性状均受2对主基因+多基因控制,2对主基因的作用方式因性状而异。主茎高和侧枝长性状以多基因遗传为主,而分枝数和结果枝数性状则以主基因遗传为主。

Main stem height (MSH), lateral branch length (LBL), total branch number (TBN) and No.of pod branches (NPB) of peanut are 4 important traits controlling plant shape.These traits were closely related with peanut yield.To offer useful information for breeding cultivars with high yield, we investigated these 4 main agronomic traits of Yuanza9102 (P1 ), Wanhua4 (P2 ), Yuan-za9102 /Wanhua4 F1 and 133 F2 lines derived from the cross of P1 ×P2 .P1 , P2 , F1 and F2 were planted in Hefei Anhui.4 traits were analyzed with mixed major gene and polygene inheritance model.Genet-ic analysis revealed that the 4 agronomic traits were controlled by 2 major genes and polygenes.Inter-actions of the 2 major genes varied with the traits.The traits MSH and LBL were mainly governed by polygenes, and TBN and NPB were mainly controlled by the 2 major genes.
