Yellow mosaic disease is one of the most important viral diseases in mungbean caused by Mungbean Yellow Mosaic Virus (MYMV) which leads to severe yield reduction and it necessitates developing MYMV resistant lines for improved crop yield. The present investigation was carried out with an objective of identification of MYMV resistant progenies through Agroinoculation. This technique was employed to examine the F₂ individuals, which were derived from a cross between Vamban (Gg) 2 (susceptible) × KMG 189 (resistant) to screen for the MYMV resistant progenies. In the field condition, MYMV infection can be evaluated by MYMV disease rating scale (1-9). Out of the 203 F₂ individuals, 30 individuals were identified as resistant to MYMV and subjected to agroinoculation. The two tandem viral constructs of MYMV, VA 221 (KA30 DNA A+KA22 DNA B) and VA 239 (KA30 DNA A+KA27 DNA B) mobilized in …
