| 摘 要： | 将正常亚麻酸含量品种合丰25与亚麻酸含量仅为2.76%的突变品系C-14杂交,利用亲本以及杂交后代群体进行5种脂肪酸含量的遗传力分析和株系间差异显著性测验。结果表明:5种脂肪酸的遗传力均较大,株系间脂肪酸含量存在极显著差异,株系内差异不显著,这就使在低世代初步筛选出优良脂肪酸组成的大豆品系成为可能;同时筛选出农艺性状和品质性状皆优良的稳定F4代品系05037,其亚麻酸含量仅为2.598%,亚油酸含量高达63.702%,农艺性状及品质性状优良,百粒重21.62 g,生育期126 d。

| Abstract: | High quality fatty acid composition in soybean is associated with nutritional value for the oil and food products.The objectives of this paper were to study the inheritance of soybean fatty acid,and to obtain stable lines with better agronomic and the quality traits combining low linolenic acid and high oleic acid and linoleic acid content.The F2 and F3 progeny segregating from a cross between Hefeng 25,a soybean cultivar with regular linolenic content,and C-14,a soybean mutant line with only 2.76% linoleni... |
