Absence of host resistance in mungbean against diseases and insect pests (Vigna radiata L. Wilczek) is one of the main reasons for its low yield in India. Mungbean Yellow Mosaic Virus (MYMV) causing yellow mosaic disease is one of the most threatening diseases of mungbean. It causes 100 per cent yield losses and has become a challenge to scientists and growers both. Transmission by whitefly is forcing chemical management but is not economically viable. Hence, host resistance is the only alternative under this circumstance. The present investigation aimed to identify MYMV resistant cultivars suitable for cultivation in North Eastern Karnataka (NEK) region. The study was conducted during kharif, 2016 consisting of nine mungbean cultivars of which four were from IIPR, Kanpur, two recently released and remaining locally cultivated. Results revealed that, IPM-2-3 cultivar released from IIPR, Kanpur showed lowest disease incidence of 6.13 per cent with highest yield of 701 kg ha-1 followed by PDM-139 which recorded 6.41 per cent disease and 676.66 kg ha-1 seed yield. The highest disease of 12.52 per cent was recorded in BGS-9 with seed yield of 464 kg ha-1 followed by in Pusa baisaki with disease incidence of 10 per cent and seed yield of 143 kg ha-1. This experiment concludes that IPM-2-3 is most suitable MYMV resistant cultivar with good yield potential followed by PDM-139. Results conclude adoption of resistant cultivar as well as use of resistant source for improving the local cultivars which enhances production and productivity of mungbean.
