INHERITANCE OF RESISTANCE TO YELLOW VEIN MOSAIC VIRUS IN OKRA (ABELMOSCHUS ESCULENTUS (L.) MOENCH)
Main Article Content
Abstract
The inheritance of resistance to yellow vein mosaic virus (YVMV) in okra was studied in crosses involving three resistant parents (Arka anamika, Punjab padmini and Arka abhay) and three susceptible parents (Pusa sawani, Local and Pusa makhmali). The parents, FI, F2, BCI and BC2 generations were groWn along with Pusa makhmali as spreader rows. Artificial inoculation under field conditions with okra YVMV was done through the bud grafting. The inheritance pattern studies by ·l test suggested that resistance to YVMV was controlled by two complementary dominant genes in susceptible x susceptible (S x S) and susceptible x resistant (S x R) crosses whereas in resistant x resistant (R x R) crosses by two duplicate dominant genes.
