Abstract: The allelic relationship of resistant genes for resistance to Mungbean Yellow Mosaic Virus (MYMV) in mungbean has been studied in the present investigation at Research cum Instructional Farm, Department of Genetics and Plant Breeding, Indira Gandhi Krishi Vishwavidyalaya, Raipur, Chhattisgarh during rabi 2015-16 and kharif 2016. The objective of this study was to determine whether the genes for resistance to MYMV in the varieties are allelic. Resistant x resistant crosses were made, a total of 12 crosses (F1s) were made during rabi 2015-16 viz, SML-1815 x Pusa Vishal, Malviya Jyoti x HUM 12, Pusa Vishal x CO 6, MH 934 x PUSA 9072, COGG 11-02 x MH 421, CO 6 x VGG 10-008, IPM 19 x COGG 11-02 (F2 shown 61 resistant: 3 susceptible segregation ratio having three independent genes, two of them dominant and one are recessive for resistance), HUM-16 x SML 1815 (F2 shown 63 resistant: 1 susceptible segregation ratio having three independent dominant genes for resistance), MH-421 x TM 96-2 (F2 shown 57 resistant: 7 susceptible segregation ratio having three genes two of them dominant genes in complementation and one independent dominant gene for resistance), PKV AKM 4 x Pusa Vishal, VGG 10-008 x Malviya Jyoti (F2 shown 13 resistant: 3 susceptible segregation ratio having two genes, one dominant genes and one recessive gene for resistance) and Samrat x VBN (Gg) 2 (allelic to each other) to build up F2 generations for scored yellow mosaic disease during kharif, 2016. The only of cross Samrat x VBN (Gg) 2 was allelic and rest of 11 crosses were non-allelic.
