甘蓝型油菜显性黄籽突变体９３３０４４产生于甘蓝型黑籽油菜复合杂交第８代。通过９３３０４４与甘蓝型油菜黑籽双低品系９３４３１和７２１—１杂交，研究种籽粒色性状遗传。在９３３０４４×９３４３１杂交组合中，Ｆ１表现黄籽，Ｆ２黄籽株与黑籽株呈３∶１分离。在９３３０４４×７２１—１杂交组合中，Ｆ１表现黑籽，Ｆ２黄籽株与黑籽株比例３∶１３。以上结果表明突变体的黄籽性状受１对显性黄籽基因和１对上位显性黑籽基因互作控制。用Ｙｃ—ｙｃ和Ｂｃ－ｂｃ表示２个基因座的２对等位基因，Ｙｃ为显性黄籽基因，Ｂｃ为上位显性黑籽基因。黄籽性状的广义遗传力ｈ２Ｂ＝６９．８８％～８６．１８％，表明突变体９３３０４４黄色种皮性状有较高的遗传能力。
The dominant yellow seed mutant 933044 in Brassica napus was produced at the 8th generation of Brassica napus hybrids. The inheritance of seed color traits was studied by crossing 933044 with the two low-yielding lines of Brassica napus, 93431 and 721-1. In 933044 × 93431 hybrid combinations, F1 showed yellow seed, F2 yellow seed and black seed were 3: 1 separation. In 933044 × 721-1 hybrids, F1 showed black seeds, F2 yellow seeds and black seeds ratio of 3:13. The above results show that the yellow seed trait of the mutant is controlled by the interaction of one pair of dominant yellow seed genes and one pair of dominant dominant black seed genes. Two pairs of alleles at two loci were represented by Yc-yc and Bc-bc, Yc was the dominant yellow seed gene, and Bc was the dominant dominant black seed gene. The general heritability of yellow seed traits h2B = 69.88% ~ 86.18%, indicating that yellow trait of 933044 mutant has higher genetic ability.
