Gram pod borer, H. armigera (Hub.) is one of the voracious pests of chickpea that needs considerable attention for the management. Thus, present studies were conducted to find out the elite genotype from the existing materials. Ten different genotypes were tested in two different locations; Upper zone (Dokri, Larkana) and Lower zone (Tandojam) of Sindh province of Pakistan. The results regarding the pod infestation revealed significant (P < 0.05 = 0.0000) difference among ten tested genotypes. Significantly, lowest percent pod infestation was recorded for NIFA- 2005 followed by DG-89 and DG-92. Significantly higher percent pod infestation was observed for Choola followed by Tamman-2013 and Sanyasi before and after harvesting during 2015 and 2016, respectively, when experiments were conducted at Upper zone. In lower zone, significantly, lowest percent pod infestation was recorded for DG-89 followed by NIFA- 2005 and DG-92. However, there was no significant difference between DG-89 and NIFA- 2005 for pod infestation. Significantly higher percent pod infestation was observed for Choola followed by Sanyasi and Dasht. During both years of trials, it was moderate in Balkassar- 2000 followed by Wanahar- 2000, Dasht and Tamman- 2013. Based on pod infestation percent, DG-89 (3) was rated as Moderate Resistance (MR) and Resistance (R) at RRI, Dokri and Tandojam, respectively. However, NIFA- 2005 (2) was rated as R at both locations; whereas, DG-92 (3), Wanahar- 2000 (3) and Balkassar-2000 (3) were rated as MR at both locations. Three varieties; Punjab- 2008 (4), Tamman- 2013 (4), and Dasht (4) were found MS at both observed locations. The variety Sanyasi (5) was rated as Susceptible (S), Choola (6) as high susceptible (HS) at Dokri, while susceptible at Tandojam. Present studies confirmed elite genotypes for Upper and lower zones of Sindh province of Pakistan that maybe used for sustainable chickpea production.
