Abstract:

Cowpea is an important grain legume crop. Among various diseases, rust caused by Uromyces phaseoli var. vignae (Barclay) Arthuris one of the major constraints of cowpea production across all cowpea growing areas of the state, thereby causing severe yield loss. The present study aimed at determining the severity of cowpea rust in six taluks of Mandya district viz., Mandya, Maddur, Malavalli, Pandavapura, Srirangapatna and Krishnarajpet during Kharif 2017. The maximum mean disease severity was recorded in Mandyataluk (39.14%) followed by Maddur taluk (34.61%) and Pandavapura taluk (31.83%) and minimum mean disease severity of 20.76 per cent was observed in Krishnarajapet taluk followed by Srirangapatna taluk (22.10%) and Malavalli taluk (27.56%). In order to identify the resistant sources against this disease an experiment was conducted to evaluate 57 genotypes under field conditions during Kharif 2017 at College of Agriculture, V. C. Farm, Mandya (University of Agricultural Sciences, Bengaluru). The disease severity varied from 0.13 to 81.45%. Out of fifty seven genotypes screened none of them were found to be immune. However, 16 genotypes were resistant, 23 genotypes were moderately resistant, 10 genotypes were moderately susceptible, 7 genotypes were susceptible and variety C-152 showed highly susceptible reaction against rust.
