Abstract:

Yellow Mosaic Virus disease (YMD) is a serious viral disease of soybean. Considering a very less attempt in studying the disease this investigation was carried out in order to arrive at the genetic basis of Yellow Mosaic Virus disease resistance of soybean. Crosses were made between highly resistant soybean varieties (DS 9712 and DS 9814) and two highly susceptible varieties (JS 335 and MAUS 609). The four cross combinations were MAUS 609 × DS 9712, MAUS 609 × DS 9814, JS 335 × DS 9712 and JS 335 × DS 9814. All true hybrids of F1 population were observed to be resistant with the score zero (0) presenting a clear visible evidence of resistance to be dominant over susceptibility. The F2 plants resulted from all four crosses were observed to segregate for YMD resistance at 3 (Resistance): 1 (Susceptible) ratio indicating the genes for resistance in the concerned parents under study to be monogenic in nature. Chi square (χ 2) test for all the four crosses showed a good fitness to 3 (Resistance): 1 (Susceptible) ratio in the F2 population at 5 % probability level indicating the monogenic dominance nature of the resistance gene. The present investigation clearly suggests that the YMD resistance trait is governed by a single dominant gene.
