Pulses are the most important and nutrient rich food preferred by most of the people for their daily consumption. Mungbean Yellow Mosaic Virus is one such diseases which reduce the grain yield tremendously However, these correlation between MYMV resistance and their related characters determined to identify the traits significantly associated with MYMV resistance. The genetic contribution of each character in building up total genetic architecture of resistance would provide a realistic basis for allocation of weightage to each of these traits which would help in genetic improvement of mungbean. The present study was undertaken to study the nine mungbean lines for MYMV incidence and MYMV intensity along with their biochemical properties related to MYMV such as chlorophyll content index, sugar content at Pulse Research Station, Dr. PDKV, Akola during kharif season 2022. In the present investigation, it was observed that, highest and lowest MYMV incidence was observed by the line AKAM-1803 62.50% (52.25) and TMB-36 2.83% (9.68), respectively. The highest and lowest MYMV intensity percent was recorded in the line AKAM-1803 33.75% (35.51) and TMB-36 1.60% (7.25), respectively. The highest and lowest chlorophyll content index was recorded by the line TMB-36 (58.8%) and AKAM-1803 (48.46%), respectively. The highest and lowest sugar content was recorded by the line TMB-36 (2.93 mg/g) and AKAM-1803 (1.95 mg/g), respectively From the correlation studies it was observed that, MYMV incidence had significantly positive correlation with MYMV intensity (r=1.0005*) whereas, On the other hand, MYMV incidence had negative correlation with chlorophyll content index (r=-0.924*) and sugar content (r=-0.956*).
