INHERITANCE OF RESISTANCE TO YELLOW VEIN MOSAIC VIRUS IN OKRA (ABELMOSCHUS ESCULENTUS (L.) MOENCH)

Published on

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.
