大白菜根肿菌接种条件筛选及资源抗病性鉴定
Screening of Optimal Inoculation Conditions and Identification of Clubroot Resistance Germplasm in Chinese Cabbage
摘要
Abstract
This study aims to screen Chinese cabbage materials resistant to Plasmodiophora brassicae,clubroot,providing superior genetic resources and a reliable identification system for breeding disease-resistant cultivars.First,artificial inoculation methods were employed to determine the optimal inoculation period and soil pH lev-el for pathogenic infection by P.brassicae.The results indicated that sowing stage was the optimal inocula-tion period with a recommended soil pH of 6.0.Under these conditions,inoculation assays were conducted on 42 materials from Hebei Agricultural University's collection and 11 commercial Chinese cabbage varieties pur chased from the market,revealing that 5 accessions exhibited stable resistance to clubroot.The findings confirmed that sowing stage inoculation at a soil pH of 6.0 significantly enhances both diagnostic accuracy and disease stability.These 5 resistant accessions serve as valuable germplasm resources for breeding disease-resistant Chinese cabbage varieties,while the established identification system provides technical support for large-scale evaluation of germplasm resources and development of disease-resistant cultivars.关键词
