无花瓣育种是油菜高产、抗病育种中的新领域,促成这一领域兴起的关键在于获得可遗传的无花瓣种质。本研究从1983年开始通过甘、白种间杂交途径,人工创建了甘蓝型油菜无花瓣种质API。-0256,并系统研究、探明了其基本特性。①形态;观察表明,APL-0256的花瓣于花瓣发育时期退化,产
Petal-free breeding is a new field in rapeseed with high yield and disease-resistant breeding. The key to the rise of this field lies in obtaining heritable petal germplasm. In this study, the petal germplasm API of Brassica napus was artificially created through the crosses between sweetpotato and white seed since 1983. -0256, and system research, proved its basic characteristics. ① Morphology; Observation showed that the petals of APL-0256 degenerated during the petal development stage
