甘蓝型油菜产量性状的遗传分析
|
摘要
探索甘蓝型油菜亲本及杂种在不同生态区的遗传效应,为品种选育提供理论基础。本研究利用加性—显性及其与环境互作的遗传模型,分析在不同生态区域亲本和杂交组合的产量性状遗传规律,估算亲本产量性状的加性遗传效应值、亲本在杂交组合中的显性遗传效应方差值、各项方差分量的比率及对F1和F2基因型与环境效应值的预测。结果表明,产量性状受到加性和显性遗传效应的影响;在遗传效应与环境互作中,单株产量、角果数和千粒重的各遗传效应都与环境互作达到了显著性,而角粒数的遗传稳定与环境互作没有显著性。不同环境下甘蓝型油菜产量性状在F1和F2世代差异较大,总体表现为大荔试验点基因型与环境的效应值高于张掖试验点基因型与环境的效应值,但千粒重却与之相反,环境条件对千粒重的后代表型影响较大。
To explore genetic effect of rapeseed parents and hybrid varieties in different ecological area,providing the theory base for breeding. This study analyzed genetic regularity of yield traits of different ecological area parents and hybrid combinations by additive dominant and the environment interaction genetic model. Estimated additive genetic effect value of parents yield traits,dominance genetic effect variance value of parents in hybrid combinations,the ratio of the variance components and genotype and environment effect value of F1 and F2. The results showed that yield traits were affected by the additive and dominant genetic; In genetic effect and environmental interactions,all the genetic effects of yield per plant and pod number per plant and thousand grain weight achieved significant with environmental interactions,but except pod grain number. Rapeseed yield traits showed bigger different of F1 and F2generation in different environment,overall performance that genotype and environment interaction value Dali was higher than Zhangye,but thousand grain weight was different,which offspring phenotype was bigger affected by environmental conditions.
