Developmental genetic analyses method for diploid seed quantitative traits was used to determine the unconditional and conditional genetic main effects and genotype environment interaction effects from embryo, cytoplasm and maternal genetic systems on crude fiber content (CFC) and crude ash content (CAC) of rapeseed meal in two growing years. The results suggested that the performance at most developmental times/stages for CFC and CAC was mainly affected by the genetic main effects. By using the conditional analysis method, for the different genetic systems, CFC and CAC were simultaneously controlled by the genetic effects from three genetic systems, especially for the maternal main effects. Also, the additive effects were more prominent at most developmental times/stages, and the improvement of both traits could be expected in earlier generation(s) in rapeseed breeding programs. The heritability analysis revealed that the maternal heritability was more prominent during seed development times, especially at maturity. Thus, it suggested that maternal plant selection could be utilized to reduce CFC and increase CAC in rapeseed meal breeding programs. The study further suggested Youcai 601 could be used for reducing CFC, while Huashuang 3 and Zhongyou 821 were suitable for increasing CAC in rapeseed, as evidenced from their predicted parent effects.
