利用BSA法检测水稻条纹叶枯病高效应抗性位点
Detection of High Effect Site for Resistance to Rice Stripe Virus by BSA
摘要
Abstract
The Jiangsu landrace rice variety Handao was previously identified as high resistance to rice stripe disease (RSV). A total of 141 F2:3 lines derived from the cross of Handao and Wuyujing 3,a variety high sensitive to RSV,were investigated by natural infection method in field,and the disease rating index was scored. Analysis of the resistant/sensitive pools by bulked segregant analysis indicated that the SSR markers RM209 and RM21 on rice chromosome 11 obviously linked to RSV resistance. A QTL for RSV was detected on rice chromosome 11 between RM209 and RM21 by the software QTL IciMapping V3 . 2 based on the principle of inclusive composite interval mapping (ICIM) with the maximum LOD score 13. 25,which explained 38. 39% of the trait variance. Additive effects of qSTV11HD was negative,indicating that the resistance allele was inherited from Handao.关键词
