油菜甘白杂种的获得及其遗传特征
Synthesis and Genetics of Hybrid Between Brassica napus and Brassica rapa
摘要
Abstract
To study the cross compatibility between Brassica napus and Brassica rapa and the genetic characteristics of the hybrid.The hybrid progenies were synthesized artificially and the morphological and fertility characteristics of the hybrid progenies were observed by microscope.The results showed that the cross-compatibility was low,and the compatibility index was between 0.15 and 0.26.The vegetative growth was normal and the morphology was similar to Brassica napus.Pollen fertility was between 40.8%and 55.3%,and the seed setting was poor.During the meiosis of hybrid pollen mother cells,many divalents were formed,a few of univalents and polyvalents were formed too.关键词
