甘蓝型油菜品种中双11根肿病抗性和除草剂抗性的遗传改良
Genetic improvement of resistance to clubroot and herbicide of Brassica napus cultivar Zhongshuang11
摘要
Abstract
Clubroot and weeds are serious threats to rapeseed production in China.To develop clubroot-resis-tant(CR)and herbicide-resistant(HR)cultivars,we developed 3 improved lines ZS11CR(CRb+PbBa8.1),ZS11HR(ALS1R+ALS3R)and ZS11CHR(CRb+PbBa8.1+ALS1R+ALS3R)by pyramiding of 2 clubroot resistance locus(CRb+PbBa8.1)and 2 herbicide-resistance locus(ALS1R+ALS3R)into rapeseed cultivar Zhongshuang 11(ZS11)with marker-assisted selection.Clubroot and herbicide resistance of the improved lines(ZS11CR,ZS11HR and ZS11CHR)was evaluated by using clubroot pathotype 4(Zhijiang,Hubei Province)and thifensulfuron herbicide(45 g a.i.ha-1),respectively.According to the results,ZS11CR and ZS11CHR were immune to pathotype 4,and ZS11HR and ZS11CHR exhibited highly resistance against thifensulfuron herbicide.In agronomic traits,ZS11CR,ZS11HR and ZS11CHR showed higher plant heights than ZS11,but no significant differences on the following traits as flowering time,number of the branch,siliques of the main inflorescence,silique length,number of seeds per si-lique and thousand seed weight.The enhanced ZS11CR line exhibited strong resistance against clubroot,while ZS11HR demonstrated high resistance against herbicide.ZS11CHR displayed resistance against both clubroot and herbicide.Additionally,these improved lines maintain outstanding agronomic characteristics,providing some poten-tial for utilization in rapeseed breeding.关键词
