Screening of certain genotypes and advance cultures of groundnut against groundnut bruchid (Caryedon serratus O)

Abstract

A Screening experiment was conducted with 52 genotypes/varieties by using no choice test to study their resistance and susceptibility to Caryedon serratus at Regional Agricultural Research Station, Nandyal. The cumulative results of six months revealed that mean no. of eggs laid were ranged from 5.82 to 157.58 eggs /100g pods and adult emergence was ranged from 9.13 to 70.76. The lowest % weight loss was recorded in Greeshma (1.96) and the highest % of weight loss was noticed in TCGS1330, K1847, K1813 and Vemana which recorded 24.83, 25.68, 28.14 and 28.24, respectively.
