本试验是利用一种生活世代较短的广东小油菜,对其异质性较大的原始群体的现蕾开花期遗传结构进行了分析,并进行了分歧性定向选择的试验,以探讨选择对于芸苔属植物油菜现蕾开花期性状分歧的作用及其遗传机制。
In this experiment, the genetic structure of the budding and flowering stage of the original population with larger heterogeneity was analyzed by using a short life rape of Guangdong Rape, and the experiment of different directional selection was conducted to explore the effect of selection on Brassica rapeseed at flowering and flowering stage of the role of divergence and its genetic mechanism.
