对春性甘蓝型油菜459×86组合的5个世代的开花时间进行了分析。结果表明:春性甘蓝型油菜的开花时间的狭义遗传率(h2G)为0.68,受2对加性基因控制,积温对开花时间的影响较大。
The flowering time of 5 generations of spring 459 × 86 combinations of Brassica napus was analyzed. The results showed that the narrow genetic ratio (h2G) of flowering time of spring rapeseed was 0.68, which was controlled by two pairs of additive genes. The accumulated temperature had a great influence on flowering time.
