摘要
枯萎病是影响绿豆产量最严重的病害之一.枯萎病病原菌厚垣孢子抗逆性强,在土壤中存活时间长,农业及化学防治方法均难以控制,因此筛选和创制抗性种质和培育抗性品种是最经济有效的途径.本研究采用剪根浸根接种法,对杂交选育的81份绿豆高代品系进行了苗期枯萎病抗性鉴定.结果显示,品系间枯萎病抗性存在明显差异;通过初级产比试验、高级产比鉴定试验、省区域试验及生产试验,培育出抗枯萎病、高产稳产、优质的绿豆新品种冀绿23.
Abstract
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.
