甘蓝型油菜无花瓣品系的选育研究

Selection and Study on the Rapeseed ofApetalous Line (Brassica napus L.)

对品种间杂交选育成的甘蓝型无花瓣品系及其有花瓣的近等基因系初步研究表明，无花瓣品系的花器组成明显比有花瓣品系增大，除一次有效分枝和一次有效角果略多外，农艺性状较差，有待继续提高。幼蕾蛋白质反相高效液相色谱分析表明，无花瓣品系花蕾较有花瓣品系多一种蛋白，其他几种蛋白含量也有明显变化。

Studies have been taken on the rapeseed of apetalous line and its isogenic line selected through crossing between the varieties of Brassica napus.The result shows that the parts of apetalous flower organ are significant enlarged than these of its near isogenic line.The apetalous line's agronomic traits are no better except that it has more branches,so they should be improved in future.The proteins in the flower buds before bloom by reversephase high performance liquid chromatography (RPHPLC) are different between apetalous line and its near isogenic line,the former has an additional protein and related to the disappearance of the petal.
