为筛选杂交亲和性好、营养优势强的杂交组合 ,生产叶用或薹用蔬菜新品种 ,采用 5个不同的油菜雄性不育系作母本 ,与十字花科不同类型的蔬菜品种远缘杂交 ,研究了远缘杂交亲和性 ,目的在于找出杂交亲和性强的油菜雄性不育系 ,以及十字花科蔬菜品种 .研究结果表明 :油菜不育系与十字花科不同类型蔬菜品种杂交 ,亲和性有比较大的差异 ,与红菜薹品种杂交亲和性最强 ;不同的不育系与同一类型品种杂交 ,以 714A的杂交亲和性最强 ,6 81A杂交亲和性最差 ;不同不育系与不同杂交组合 F1 杂交 ,除少数杂交组合外 ,大多数杂交组合亲和性较差 ;6 81A与特异性状的十字花科蔬菜品种杂交 ,亲和性均较差 .
To screen hybrids with good compatibility and strong nutrition superiority, new vegetable varieties for leaves or sedges were produced. Five different male sterile lines of rapeseed were used as female parent and distantly crossed with different types of cruciferous vegetable varieties The aim of the study was to find out the male sterile lines and the cruciferous vegetable varieties with high affinity and affinity.The results showed that the male sterile lines of Brassica napus and the cruciferous different types of vegetables Hybrid and affinity, but had the strongest hybridization affinity with the red flowering Chinese cabbage breeds; different male sterile lines crossed with the same type of hybrid, the hybrid with 714A had the strongest hybridization affinity and the hybrid with 6 81A The worst among them; F1 hybrids of different CMS lines with different F1 hybrids, with the exception of a few hybrid combinations, most of the hybrid combinations had poor affinity; 681A crossed with cruciferous vegetables with specific traits with poor affinity.
