Germplasm Creation and New Variety Breeding for Fusarium Wilt Resistance in Mung Bean
Fusarium wilt is one of the most serious diseases affecting the yield of mung bean.Chlamydospores of the pathogen have strong resistance to stress and long survival duration in soil,so it is difficult to control them by agricultural and chemical methods.The most economic and effective method is to screen and create germplasm and breed new varieties with disease resistance.The 81 bred lines of mung bean were identified for their resistance to Fusarium wilt by root-cutting and root-soaking inoculation in seedling stage.The results showed that there were obvious resistant differences among the strains.Jilü 23,a new mung bean variety with high resistance to Fusarium wilt,high and stable yield and good quality,was bred through primary yield test,high yield appraisal test,provincial regional test and production test.
