Identification of mungbean genotypes with multiple disease resistance

Abstract

Mungbean is a high-protein legume and is widely cultivated in a variety of cropping systems. Foliar diseases like powdery mildew, anthracnose and mungbean yellow mosaic virus (MYMV) not only limit the productivity but also affect the physical quality of seeds rendering them unusable. In this study 130 advanced breeding lines were screened for multiple disease resistance using infector row method. Screening for powdery mildew and anthracnose was done during kharif 2021 and for MYMV during summer 2022 with two trials per season, each under protected and unprotected conditions to record the yield differences due to the diseases. Of the 130 advanced breeding lines screened, Vigna trilobata was found to show multiple disease resistance. The advanced breeding lines such as DGG-227, V-02-709, DGG-96, DGG-21 showed resistant reaction for anthracnose. GPM-19 was the only genotype which was found to be resistant to powdery mildew. During summer 2022, 18 genotypes showed resistant reaction towards MYMV.
