【摘要】 用中抗和高抗细菌性条斑病(简称细条病)的两个籼稻品种明恢86和佳辐占为亲本构建了F2群体,应用SSR标记在水稻第2染色体的RM279～RM154之间检测到1个与水稻细条病抗性有关的QTL,其可解释遗传表型变异的13.7%,其加性效应为0.9576,来自抗病亲本佳辐占。更多还原

【Abstract】 A F2 population from a cross between two indica rice cultivars,Minghui86 and Jiafuzhan,which are moderately and highly resistant to bacterial leaf streak (BLS) respectively,was established.One QTL conferring the resistance to BLS was detected in the region between microsatellite markers RM279 and RM154 on chromosome 2 of rice (O.sativa L.spp.indica) using SSR (simple sequence repeats) marker,which could explain 13.7% of the phenotypic variation.Its additive effect from Jiafuzhan is 0.9576.更多还原
