摘  要：
为探明花生脂肪和脂肪酸含量的遗传机制,采用主基因+多基因混合遗传模型分析方法,分析了栽培/野生种间杂交组合白沙1016×A.monticola的216个重组自交系家系(F10)及其亲本的脂肪及脂肪酸组分含量,建立了相应的遗传模型,并进行了性状间的相关性分析。遗传模型分析结果表明,脂肪和花生酸含量的遗传模型为C,无主基因受多基因控制,其多基因遗传率分别为98.55%和84.81%;油酸、亚油酸、棕榈酸、山嵛酸和二十四烷酸的遗传均表现为受两对主基因+多基因控制,其主基因遗传率分别为45.08%、46.13%、44.85%、66.55%和65.98%。相关性分析显示,花生脂肪含量与油酸和花生酸含量呈极显著正相关,与亚油酸、棕榈酸、山嵛酸和二十四烷酸含量之间呈极显著负相关。因此在花生高油育种中,提高脂肪含量要注重多基因的积累;选育高油酸等优质专用型品种时,关注主基因遗传的作用时还要考虑到多基因的利用。

摘  要：
To better understand the genetic mechanism of fatty acid traits and to facilitate peanut quality enhancement,genetics of a F10 population derived from interspecific cross Baisha 1016 × A. monticola was analyzed using major gene plus polygene mixed inheritance model. 216 recombinant inbred lines( RILs) were investigated to build a genetic model. Results showed that contents of both fat and arachic acid were controlled by polygenes,and their heritability were 98. 55% and 84. 81% respectively. Each with 5 components,including oleic acid,linoleic acid,palmitic acid,behenic acid and lignoceric acid,were controlled by 2 major genes plus polygenes. Their major gene heritability were 45. 08%,46. 13%,44. 85%,66. 55% and 65. 98% respectively. Correlation analysis showed that both oleic acid and arachic acid contents were highly significantly( positive) correlated to peanut fat content.Linoleic acid,palmitic acid,behenic acid and lignoceric acid contents were highly significantly( negative) correlated to peanut fat content. Therefore,high- oil peanut breeding should focus on polygenes accumulation. And high oleic acid and other major fatty acid breeding should focus on both major genes and polygenes.
