摘要
观察研究结果表明：甘蓝型纯黄籽双低新品系YR5602是十分稳定的黄籽材料。5个年度的群体黄籽株率均为100％，黄籽频率也均为100％，黄籽度高达1．94～2．00，除种脐颜色稍深外，种皮全部均为淡黄色且无斑点。YR5602的粒色与枝次、枝序、果位、粒位以及不同的农艺措施等均无明显关系。YR5602是极为珍贵的油菜种质资源。
The results show that YR5602 is a new stable yellow seed line. The plant rate with yellow seeds, yellow seed frequency and yellow seed degree are up to 100%, 100% and 1.94～2.00 respectively during 5 years and the color of seed coat all is yellowish and without spots except the yellow seed hilum. There is no significant correlation between seed color and the order of branch, pod and seed or different agronomic measures. Therefore, YR5602 is a special rare germplasm resource in rape breeding.
