利用16个白菜型油菜品种配制44个杂交组合，通过分析和比较双亲和F1代的株果数、果粒数和干粒重，提出当地品种“青油241”、“宁交5号”、芬兰品种“Hja98862／7”对提高每用粒数、单株角果数有明显的作用。西藏的大粒品种是改进千粒重的基因源。地理远距离的瑞典、加拿大、日本品种与国内品种杂交，对增加后代的株果数有明显的遗传影响，对果粒数的增加品种间表现差异较大。 In this study, 44 hybrid combinations were prepared from 16 Chinese cabbage varieties. By analyzing and comparing the fruit number, fruit number and dry weight of parents and F1 generation, we proposed that the local varieties “Qingyou 241 ”, “Ningjiao 5 ”“, Finland ”Hja98862 / 7 " to improve the number of grains per use, the number of pods per plant has a significant role. Large-grain varieties in Tibet are sources of genes that improve grain weight. Geographically distant cross between Sweden, Canada, Japan and domestic breeds had obvious genetic effects on increasing the number of fruit trees of the offspring, and there were significant differences among varieties with increasing number of fruit grains.
