Screening of Cluster Bean Genotypes/ Varieties for Resistance to Xanthomonas axonopodis pv. cyamopsidis Using Two Methods of Inoculation

Clusterbean [Cyamopsis tetragonaloba (L.) Taub is an arid and semi-arid legume crop belonging to the family leguminaceae. It a drought enduring leguminous because of its profound tap rooting system has high capability get well from water stress. Total fifty-nine varieties/genotypes clusterbean were screened under artificial Inoculation field conditions at College Research Farm, Agriculture, Bikaner against bacterial blight disease during Kharif season 2018 2019. Two alternative inoculation techniques-seed foliar sprays suspension employed test for resistance Xanthomonas axonopodis pv. cyamopsidis infection. (2.5x108cfu/ml). Out 59 varieties, only one variety RGC-1066 found resistant disease, 17 moderately resistant, susceptible 24 varieties susceptible. No highly blight.
