油研系列杂交油菜高含油量的表现及高油分高蛋白选育技术研究 Ⅲ.高油分高蛋白的转育技术

Performance of High Oil Content of Youyan Series Varieties and Its Breeding Techniques of High Oil and Protein Content Ⅲ.High oil and protein trans-breeding techniques

选择具有油分蛋白总量在70%以上的材料与需要改良亲本杂交,其F2代分离出油分蛋白总量在70%以上的单株,其含油率和种子蛋白平均可达48%和23%左右,在此基础上再通过F3、F4代定向选择,可使改良亲本具有相应稳定的高油分高蛋白的优良性状。

The plants with 48% oil content and 23% protein content were selected from F2 generation of 82278A（a parent with over 70% total oil and protein content） × 1702（the need modified parent）.The needed modified parent with stable high oil and protein content can be bred through directive selection of the F3 and F4.
