EVALUATION OF PIGEON PEA INTERSPECIFIC DERIVATIVES FOR RESISTANCE TO SPOTTED POD BORER, MARUCA VITRATA (FABRICIUS)

The present study was carried out to screen 40 advance BC 1 F 8 /F 9 pigeon pea interspecific derivatives of C. scarabaeoides (ICP 15683) C. cajan (ICPL 20329) for resistance to spotted pod borer, Maruca vitrata during kharif 2022 at Ludhiana.The population of M. vitrata peaked during the 41 st Standard Meteorological Week (SMW), coinciding with Pigeon pea flowering.The pod damage ranged from 3.66 per cent to 25.41 per cent in different interspecific derivatives.Among 40 derivatives, seven (AL 2593, AL 2609, AL 2610, AL 2611, AL 2612, AL 2613 and AL 2614) showed resistance to M. vitrata, owing to indeterminate growth, higher pod count, seed yield and wild introgression.
