Field screening of pigeonpea genotypes to pod borer, Helicoverpa armigera

A field experiment was conducted during Kharif, 2018 to screen twenty pigeonpea genotypes for their resistance or susceptible to gram pod borer, Helicoverpa armigera. The results showed that the genotypes, RKPV 527-01, GJP 1606, JKM 189, BDN 711, ICPL-87119, RVSA 16-4, IPA 15-05 and LRG 467 were found resistant with regard to per cent pod damage and eight genotypes viz., RVSA 16-4(1.59), JKM 189(1.64), LRG 467 (2.20), GJP 1606(2.23), BDN 711(2.29), RKPV 527-01(2.58), ICPL 87119(2.58) and IPA 15-05(2.88) were found resistant with regard to per cent seed damage and were grouped under resistant category as they have recorded the pest suspectibility rating ranging from 1 to 5. Maximum seed yield was recorded in RVSA 16-4 (987.33 kg ha-1), followed by LRG 467(958.00), WRP 1(812.33) and RKPV 527-01(793.87), while minimum seed yield was recorded in ICPL 8863 (360.67 kg ha-1).
