Abstract

A field experiment was conducted at Centre of excellence for Research on Pulses, S. D. Agricultural University, Sardarkrushinagar during Kharif 2010. Among twenty genotypes of cowpea, GC-706 recorded the lowest spotted pod borer population (0.06 larvae/plant) and pod damage (8.89%), while maximum larval population (1.96 larvae/plant) and pod damage (24.30%) was recorded in GC-12. Genotype GC-706 (981.48 kg/ha) also achieved higher yield of cowpea followed by genotypes/varieties GC-203, GC-521, GC-815, GC-510, RC-101, GC-723 and GC-2. Whereas, lowest yield was recorded in genotype GC-12 (511.11 kg/ha). Thus from the overall results on of larval population and poddamage, itcan be inferred that genotypes GC-706, GC-203, GC-510 and GC-521 proved resistant, while remaining genotypes found susceptible to this pest.
