大豆的油分含量在20.1%以下时与产量呈正相关趋势,20.1%以上时与产量呈负相关趋势。因此,大豆高油育种具有一定的难度,应广泛搜集、筛选和创造高油中间材料,采用以有性杂交育种为主,结合诱变育种和外源DNA导入等方法进行选育是有效的。 Soybean oil content below 20.1% when the yield was positively correlated with the trend, 20.1% above the yield was negatively correlated trend. Therefore, soybean high oil breeding has a certain degree of difficulty, should be widely collected, screening and creation of high oil intermediate materials, the use of sexual hybrid breeding, combined with mutation breeding and introduction of foreign DNA methods such as breeding is effective.
