对5个黄籽和1个黑籽B的种子颜色遗传进行了研究。油菜种质黄籽类型间的远缘杂交表明，四个变种。来自印度的黄色Sarson种质具有相同的种子颜色基因型，但与瑞典的黄色种子育种系不同。种子颜色以黑色为主，黄色次之。F_2（包括正反交）和BC_1（F_1与黄籽亲本回交）的粒色分离模式表明，黑粒色受一对显性基因控制。种子颜色主要受母体基因型控制，但受母体与胚乳和/或胚基因型之间的相互作用影响。用于开发黄色种子B。油菜基因型，再合成B。含有黄色种子基因的油菜品系（Chen等，1988）与B杂交。黄/棕色种子的甘蓝型油菜，或具有黄种子的B。carinata。在涉及B的杂交中发现了黄色种子的F2植株。甘蓝型油菜育种系然而，这个黄色种子的字符没有繁殖真正的F4。黄籽F3植株与单基因组控制的黑籽B之间的杂交。甘蓝型油菜再合成材料的黑籽性状在B. alboglabra基因组可能受两对独立的显性基因控制，且存在重复效应。再合成的B之间的可交叉性。甘蓝型油菜品系为母本，B. carinata作为雄性的比例较高。F1植株的不育性阻止了进一步的育种进展，以发育黄籽B。通过这一战略。
Seed colour inheritance was studied in five yellow-seeded and one black-seeded B. campestris accessions. Diallel crosses between the yellow-seeded types indicated that the four var. yellow sarson accessions of Indian origin had the same genotype for seed colour but were different from the Swedish yellow-seeded breeding line. Black seed colour was dominant over yellow. The segregation patterns for seed colour in F2 (including reciprocals) and BC1 (backcross of F1 to the yellow-seeded parent) indicated that the black seed colour was conditioned by a single dominant gene. Seed colour was mainly controlled by the maternal genotype but influenced by the interplay between the maternal and endosperm and/or embryonic genotypes. For developing yellow-seeded B. napus genotypes, resynthesized B. napus lines containing genes for yellow seed (Chen et al., 1988) were crossed with B. napus of yellow/brown seeds, or with yellow-seeded B. carinata. Yellow-seeded F2 plants were found in the crosses that involved the B. napus breeding line. However, this yellow-seeded character did not breed true up to F4. Crosses between a yellow-seeded F3 plant and a monogenomically controlled black-seeded B. napus line of resynthesized origin revealed that the black-seeded trait in the B. alboglabra genome was possibly governed by two independently dominant genes with duplicated effect. Crossability between the resynthesized B. napus lines as female and B. carinata as male was fairly high. The sterility of the F1 plants prevented further breeding progress for developing yellow-seeded B. napus by this strategy.
