Establishment of resistance identification technology system for mung bean Pythium myriotylum root rot and screening of resistant resources
摘要
Abstract
The mung bean root rot caused by Pythium myriotylum is a recently reported soil-borne disease that presents a considerable pathogenic hazard to mung bean.To establish a laboratory technique for assessing resistance of mung bean a-gainst P.myriotylum and achieve rapid and effective screening of disease-resistant resources,three inoculation methods inclu-ding root irrigation inoculation method,mycelial layer inoculation method and hypocotyl wound inoculation method were used to evaluate and compare the resistance of mung bean to P.myriotylum.The results showed that the mycelial layer inoculation method had the advantages of simple operation,short test period,and stable results.To screen mung bean germplasm re-sources with resistance to root rot disease caused by P.myriotylum,394 collected mung bean germplasm resources were as-sessed using the mycelial layer inoculation method.The resultsshowed that 98.48%(388 samples)of germplasms exhibited medium to high susceptibility,with disease index(DI)>40.0,only six germplasms(1.52%)exhibited in-termediate resistance(20.0<DI≤40.0),and none showed resistance or immunity(DI≤20.0).The results indicated that the collected mung bean germplasms with resistance to P.myriotylum were scarce.In this study,we established a potential method for identifying resistance resources of mung bean against root rot disease caused by Pythium species.关键词
