摘要
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,研究大豆高脂肪组合初世代脂肪含量遗传及亲本的关系。结果表明:F4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,F4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,F4代出现高脂肪材料的几率高。F4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。
Seven high yield or high-oil soybean were selected and eight crosses were made according to NCII design, the heredity of oil content in F4 and its correlation with parents were researched. The variation of oil content in F4 related with the difference between parents, and obvious difference between parents resulted in more variation in the oil content of F4. When the oil content of both parents were .high, and the maturating time of them are very different, the high-oil F4 plants tended to derive from those crosses with both highoil content and significant difference in maturity. The oil content of F4 generation had negtive correlation with the difference between parents, and had positive correlation with male parent and its correlation with oil content of female parent and mid-parent reached extremely significant.
