强冬性白菜型油菜自交亲和系主要特征特性分析
Characterization of the main feature in self-compatibility strong winter rapeseed(Brassica rapa L.)
摘要
Abstract
Preserving purity is difficult in self-incompatibility crops.To better understand Brassica rapa with self-compatibility in strong winter rapeseed,a two-year experiment was carried out to investigate self-compatibility index,pollen-stigma interactions,major botanical characteristics at seedling stage,agronomic traits and quality traits.Results indicated that self-incompatibility in 50 strong winter rapeseed lines had a large magnitude of varia-tion,thus according to the degree of self-compatibility,they could be categorized into 4 types:highly self-compati-ble,self-compatible,self-incompatible,and highly self-incompatible.Although no difference in pollen morphology between self-compatibility and self-incompatibility materials,the stigma papillae cell surfaces of the compatible material that was not pollinated showed a greater amount of flocculent attachments.Moreover,numbers of pollen grains and pollen tubes sprouted from the stigma after self-pollination were significantly higher in the self-compati-bility than in the self-incompatibility.In terms of botanical characteristics,agronomic and quality traits,there were no significant differences between self-compatibility materials and self-incompatibility materials,indicating that their self-compatibility could be stably inherited and had excellent agronomic traits and quality.关键词
