本文论述了甘蓝型油菜无花瓣种质无花瓣１号的选育过程，并从遗传、生理、生态、抗性、农艺性状等方面，对该种质进行系统的鉴定与研究。指出无花瓣种质在低能耗与抗病性上具有较高育种潜势，是进一步选育具有高产、抗病、优质综合性状油菜品种的重要资源。
In this paper, the breeding process of Petal No.1, a petal germplasm of Brassica napus, was discussed. The germplasm was systematically identified and studied from the aspects of genetics, physiology, ecology, resistance and agronomic traits. It is pointed out that petal germplasm has high breeding potential in low energy consumption and disease resistance, which is an important resource for further breeding rapeseed with high yield, disease resistance and high quality.
