Evaluation of Fodder Cowpea Genotypes for Tolerance to Semilooper (Plusia nigrisigna Wlk.)

Abstract

One hundred and sixty two accessions of fodder cowpea were screened against semilooper (Plusia nigrisigna Wlk.)
under natural infestation conditions for four consecutive years. The mean incidence of semilooper ranged from
2.14-4.57% in promising genotypes EC24102-1 (2.14%), IL-1063 (3.89%), IL-05-08 (3.99%) and EC240884
(4.57%) as compared to 14.91-24.74% in the check lines. The entry EC24102-1 may be used as a donor for resistant
breeding programmes.
