Pathogenicity of Physiological Races of Rice Blast Disease in Jiangxi Province, Blast-resistant Performance and Application Evaluation of A Set of New High-quality Rice Germplasms
摘要
Abstract
We comprehensively analyzed the pathogenicity of main physiological races of rice blast disease in Jiangxi prov-ince, and identified the blast resistance of collected 26 new rice germplasms. The results showed that: rice blast in Jiangxi con-tained 25 physiological races in 6 groups(ZA, ZB, ZC, ZD, ZF, ZG), and majority of these physiological races possessed a moderate pathogenicity; seven blast-resistant genes[Pi-k(C), Pi-k, Pi-9(t), Pi-z5, Pi-1(1), Pi-kp(C)and Pi-kp]in rice all had a resistant frequency of more than 60%; twenty-six rice germplasms all had a stronger resistance to leaf blast, but they all were susceptible to neck blast, and only 5 varieties were moderately susceptible to neck blast; among 13 rice varieties with both higher yield and better rice appearance quality,only Fan 1405 and Fan 1409 reached the national standard grade-1 for rice quality.关键词
