SCREENING OF GREEN GRAM GENOTYPES AGAINST SPOTTED POD BORER MARUCA VITRATA (F.)

Abstract

This study evalutes 20 gentotypes of green gram Vigna radiata (L.) Wilczek for their susceptibility levels against the spotted pod borer Maruca vitrata (F.). The experiment was done during kharif 2014 and 2015 at the Agricultural Research Farm, Banaras Hindu University, Varanasi, Uttar Pradesh. The infestation was assessed at the flowering stage based on larval incidence/ plant. The results revealed that the incidence was observed in the 37th standard meteorological week (SMW) with a peak during the 40th SMW, and varied from 0.53 to 3.01 larva/ plant.Maximum larval population was observed in IPM 306-6 followed by IPM 05-3-22 and ML 1256 and the least with PM-5 followed by IPM 306-1 and ML 515. The genotype PM-5 (7.72 q/ ha) closely followed by IPM 306-1 (6.96 q/ ha) and HUM-16 (6.58 q/ ha) gave the maximum yield. © 2019, The Entomological Society of India. All rights reserved.
