对油研５号制种中，其母本植株上不同角粒数角果诸性状研究表明：角粒数的多少与角果大小有关，角果各组成部分重对角粒重起着重要作用。随着角粒数的增加，角果的结籽率、形成种子粒数、角粒重、生产力、经济系数、总角果壳重、角果生物产量、对产量的贡献率呈现有规律的递增，千粒重和角果百分率呈现有规律的递减。不同角粒数角果百分率中，萝卜角占有效角的比例为２／５，对产量的贡献率约为１／１０。除千粒重外，其他性状都是正常角优于萝卜角。
The results showed that the number of croaker is related to the size of pod and the weight of podocarp plays an important role in the seed-setting of Yoyan No.5. . With the increase of number of grains, the seed setting rate, seed number, grain weight, productivity, economic coefficient, total fruit shell weight, fruit yield and the contribution rate to yield increased regularly , 1000-grain weight and percentage of pods showed a regular decline. The number of different Kok Kok Kok percentage, radish angle accounted for the effective ratio of 2/5, the contribution rate of about 1/10. Except 1000 grain weight, all the other traits are better than radish angle.
