【摘要】 为探明大豆种子脂肪氧化酶的缺失是否会对大豆的农艺性状造成影响 ,对从中国南方 10省 (市 )征集的174份大豆种质资源中筛选出的种子脂肪氧化酶缺失体与非缺失体材料和从国外引种的缺失体近等位基因系农艺性状间的差异进行了研究 .结果表明 ,大豆种子脂肪氧化酶的缺失对开花期、生育期、株高、节数、分枝数、单株荚数、单株粒数、单株产量、百粒重、害虫危害种子程度、脂肪和蛋白质含量等主要农艺性状都没有明显影响 .对大豆资源的统计分析结果表明 ,大豆种子脂肪氧化酶的缺失频率与生态类型无关 ,与籽粒颜色、形状和脐色有关 .更多还原

【Abstract】 Differences of agronomic characteristics of isolines were compared between the mutants introduced from abroad,and the lipoxygenase mutants and normal soybean materials selected from 174 varieties of bean germ plasm resources gathered from 10 provinces in the southern part of China.The effects of the lacking of the lipoxygenases in soybean seeds on agronomic characteristics was investigated. The results show that during the growth and development of soybean, the lacking of the lipoxygenases have no effects on flowering date, growth period, plant height, number of node, number of branch, number of pod per plant, number of seed per plant, yield per plant, weight of 100 seeds, harming degree of pest on seeds, fat contents, and protein contents. Through statistical analysis of soybean resources, the results show that the mutant frequency of lipoxygenases in soybean seed has no relation with ecological types,but with seed color, seed form, and hilum color.更多还原
