| Description: |
Seven Vigna species were studied for yellow mosaic virus resistance during rainy season. The YMV resistant species V. umbellata was attempted to cross with the YMV susceptible species in line x tester fashion using hand emasculation and pollination technique. The results demonstrated that severe infection of yellow mosaic virus at early seedling growth stage up to maturity produced less pods and those produced are either empty or with infected seeds. Different combining compatibilities were also observed among the studied Vigna species. Ricebean exhibited more compatability with V. mungo followed by V. sublobata. The genotypes of V. luteola, V. trilobata, V. aconitifolia and V. unguiculata were found incompatible in present investigation. The number of F1 seeds in the crossed pod ranged from 1 to 3. Immature or shriveled seeds of crossed pods revealed integrity of the various Vigna species. Present investigations suggests ricebean as a potential natural resource for YMV resistance and this trait can be introduced in agriculturally important but YMV susceptible crops through breeding. In near future, improved varieties of food grain legumes may surplus the sustainable agriculture production in biotic stress prone areas. |
