Summary
Two Abelmoschus species, viz., A. manihot (L.) Medik and A. manihot (L.) Medik ssp. manihot, resistant to Okra yellow vein mosaic (YVM) were crossed to A. esculentus cv. ‘Pusa Sawani’, a susceptible culture. The hybrids were resistant and partially fertile. Segregation pattern for disease reaction in F2, BC1 and subsequent generations of the two crosses revealed that resistance to YVM is controlled by a single dominant gene in each species.
