2011年3月,于湖南农业大学试验田甘蓝型双低油菜GX–49品系中发现了株雄性不育株,命名为72A。利用石蜡切片技术对其败育时期花药发育进行观察,通过与双低甘蓝型早熟油菜品系GZ–4和GZ–20–2杂交,对其遗传动态进行分析。结果表明,72A为典型的无花粉囊败育型,且为单基因控制的隐性细胞核雄性不育。

We found a male-sterile plant, named ＂72A＂, in the GX-49 strains （Brassica napus L.） in Hunan Agricultural University experimental field in March, 2011 （Changsha, Hunan, China）. During its abortion stage we observed its anther development carefuuly by using the technology of paraffin sections. Through the dynamic analysis of its genetic characteristics after it was hybridized with double-low, early maturity Brassica napus GZ ~4 and GZ-20-2, we found that 72A belonged to no pollen sac abortion type and its recessive genic m...
