Preliminary screening and characterization of clubroot resistant germplasm resources in cruciferous
摘要
Abstract
Clubroot disease has spread explosively in recent years,posing a serious threat to cruciferous crop production.Take rapeseed for example,according to the statistics,until year 2022 the incidence of the clubroot has exceeded 1.33 million hectares in China.Breeding for resistant cultivars is considered as the most efficient and eco-nomical way to prevent clubroot disease spreading.However,the current CR cultivars mostly used CR loci of PbBa8.1 or CRb.Due to the complexity and diversity of Plasmodiophora brassicae from different locations,resources for resistant germplasm need to be explored.In this study,14 clubroot-resistant Chinese cabbages were character-ized using different clubroot pathogens and molecular markers for known CR loci.We found that among them,five materials,DG117,ZS105,SG01,SR06 and JQ07 did not contain CRb locus,and their disease resistance were stron-ger than Huashuang5R/Huayouza5R.At last,KL02 containing the CRb locus showed stronger resistance to Pb XM(strain from Xinmin)than 409R,therefore it may contain other novel loci leading to better resistance.These six Chi-nese cabbage resources can be considerd as new resistance resources and could be utilized in future breeding work for CR Brassica napus.关键词
