菜心不同转育世代异源胞质不育系的叶绿素和蛋白质含量分析

Analysis of Chlorophyll and Protein Content of Allo-cytoplasmic Male Sterile Line in Different Transferring Generations of Brassica parachinensis

以Ogura萝卜胞质和改良萝卜胞质为母本,以不同熟性品种的菜心为父本,获得不同世代的杂交组合,以探索菜心不同转育世代的品质特性。结果表明:"改良萝卜胞质80天"和"49菜心"雄性不育系与晚熟品种"特青迟心4号"(TQ)配制的杂交组合,其F1与母本分别在回交第5代和回交第6代叶绿素含量最高,可作为优良的组合;以"改良萝卜胞质80天"菜心雄性不育系为母本,以中熟品种"C-70"为轮回亲本,其F1与母本回交第4代的蛋白质含量最高,可作为优良的组合。

Hybridized combinations of different generations were obtained by Ogura radish CMS and improved radish CMS as female parent, and different maturity varieties of Brassica parachinensis as male parent,in order to study the effects of qualities on brassica parachinensis in different transferring gengerations. The results showed that the hybridized combinations of brassica parachinensis in mate sterile line of improved radish CMS eighty-day and forty nine brassica parachinensis line respectively and the late maturing ＇ Teqingchixin 4 ~ （TQ） were elite, the chlorophyll, cotent was highest in the fourth and fifth generation of back-cross. The improved radish CMS eighty-day of Brassica parachinensis line was used as female parent,and mid-ripening cultivar C-70 was used as recurrent parent,the protein content was highest in the fourth generation of back-cross. It was an optimal combination.
