贵州省水稻主栽品种抗稻曲病性鉴定与评价
Identification and evaluation of resistance of main rice cultivars to rice false smut in Guizhou
摘要
Abstract
[Objective] The resistance of main rice cultivars to rice false smut in Guizhou was ascertained to provide references for the selection and layout of rice cultivars in Guizhou Province.[Method]The disease resistance of 20 cultivars to rice false smut was identified by artificial injection into panicle before flower using cultured conidia suspension.[Result]Of the 20 cultivars,Fuyou 102 with moderate resistance (comprehensive resistant index=3.0) was the most resistant (15.40％),in which the number of rice false smut balls was up to 0.3 per panicle.The second most resistant was Tyou 272 with disease incidence of 23.10％ (comprehensive resistant index=4.1),in which the number of rice false smut balls was up to 0.5 per panicle.Seven cultivars were susceptible (S) and eleven cultivars highly susceptible (HS),of which the highest disease incidence and the count of rice false smut balls per panicle were up to 86.70％ and 8.2,respectively.[Conclusion]The resistance level of the tested cultivars was relatively low to rice false smut with the exception of Fuyou 102 (moderate resistance).Thus,Fuyou 102 should be extended in areas seriously hit by rice false smut in Guizhou.关键词
