Abstract
The field experiment was conducted at the Research cum Instructional farm, IGKV, Raipur (C.G.) during Kharif 2024 to screen 87 mungbean germplasm lines against the pod borer complex. Out of 87 germplasm it was seen that DGGV 2(5) exhibited the lowest pod damage (0.50%) caused by Helicoverpa armigera, while LGG 460(5) recorded minimal damage (2.25%) from Maruca vitrata. In terms of productivity, SML 1082(1) yielded the highest grain output (1163.00 kg/ha), followed closely by GJM 1824 (1133.33 kg/ha). Resistance categorization revealed 25 lines as resistant, 38 as moderately resistant, 16 as tolerant, 6 equivalents to the check variety, and 2 as moderately susceptible. No lines were immune, highly resistant, susceptible, or highly susceptible, indicating a narrow resistance spectrum.
