黄籽油菜的选育和含油量的研究

STADY OF BREEDING OF THE YELLOW RAPE SEED AND CONTENT OIL

单位面积的产油量是由种籽产量,含油量和出油率所决定,油菜含油量的遗传性较稳定,受外界环境影响较小,据瑞典奥尔森等(Closson.G 等1963)研究,甘兰型不同材料含油量的变异系数为3.6—8.4%,而单株种子产量的变异系数为60%,提高含油量与出油率育种比提高种子产量育种更易见效,早在40年代,瑞典等就已开展了高含油量育种工作,日本、加拿大相继进行了研究,先后育成一批高含油量的油菜品种如日本的农林43,含油量49%,加拿大的齐菲,含油量51%等。
