[目的]研究大豆高脂肪组合初世代脂肪含量遗传及亲本的关系.[方法]选择高产或高脂肪的7个大豆亲本,采用NCII设计,配成8个组合.[结果]F5代脂肪含量的变异大小与双亲脂肪含量的差异有关,双亲的差异越大,F5代脂肪含量的变异程度也越大.双亲脂肪含量均高,且双亲熟期差异较大,F5代出现高脂肪材料的几率高.F5代脂肪含量与双亲的差值呈显著负相关;与父本的脂肪含量呈显著正相关;与母本脂肪含量及中亲值呈极显著正相关.[结论]该研究结果为高脂肪大豆选育提供参考.

[Objective] This paper aims to study the heredity and parental correlation of the oil content of the beginning of the generation at high- oil content soybean. [Methods] Seven high yield or high-oil content soybean are selected and eight crosses are made according to the NCII de- sign. [Results] The variation of oil content in F5 relates with the difference between parents. The more the differences between both parents have, the more variations of the oil content of F5 become. When the oil content of both parents are high, and the maturating time of them are very different, the probability of high-oil plant in F5 derived from these cross are high. The oil content of F5 generation has negative correlation with the different between both parents and has positive correlation with the oil content of male parent and significant positive correlation with the oil content of female parent and mid-parent. [Conclusions] This study result provide reference for the seedling of High-oil Content Soybean.
