不结球白菜抗根肿病种质资源的创制和抗性鉴定OACSTPCD
Creation and resistance identification of clubroot resistance germplasms in non-heading Chinese cabbage
以抗根肿病大白菜和不结球白菜为试材进行杂交,通过连续五代回交转育和自交分离纯化,创制了抗根肿病不结球白菜新种质2份,编号为BC20和Q20,并进行了比较试验.结果表明:创制的2份新种质综合农艺性状接近不结球白菜;属于中箕类型;生长势强;叶片绿色,宽椭圆;叶柄匙形,中长较窄,浅绿;BC20叶面较平整,Q20叶面略皱.该种质的创制为进一步培育抗根肿病不结球白菜新品种奠定了资源基础.
Chinese cabbage,resistant-clubroot disease and non-heading Chinese cabbage were used as test materials.Through hybridization,backcrossing,and self-crossing for five generations,two new resistant-clubroot disease germplasm resources were created and numbered BC20 and Q20.Every generation was conducted vaccination identification and compared with agronomic characters.The results showed that the two new germplasms had the resistance of clubroot disease and the similar agronomic traits of Q16.The plants were upright with medium height and grew fast and strongly.They had green leaves,wide elliptic leaves,spatula-shaped petioles,medium length and narrow width.The BC20 had smoother leaves while Q20's were slightly wrinkl.The new germplasms will provide a basic resource for breeding new varieties of clubroot-resistant non-heading Chinese cabbage.
