Abstract
The growth responses of ten genetically different urdbean cultivars to yellow mosaic virus infection revealed that the virus may affect both the vegetative growth and the yield components. Various urdbean cuILivars exhibited 21.62 to 39.81% decrease in plant height, 25.81 to 55.63% decrease in number of branches, 21.85 to 59.70% decrease in number of leaves and 45.52 to 84.12% decrease in dry stem weight. Similarly, the urdbean cultivars suffered from 43.08 to 82.5% decrease in number of pods planr l, 25.32 to 37.00% decrease in pod size, 22.73 to 30.55% decrease in number of seeds per pod, 30.55 to 57.40% decrease in 1oo-seed weight and 29.29 to 77.56% decrease in plant yield.
