Abstract:
A research was conducted at the vegetable research centre in GBPUA&T Pantnagar in 2022 showed that the YVMV Trait's complicated genetic inheritance pattern for disease tolerance. Generation means analysis involving six generations (P₁, P₂, F₁, F₂, BC₁P₁ and BC₁P₂) was evaluated in randomized block design with two replications at performed to investigate okra traits. However, generation mean analysis demonstrated that the inheritance of disease tolerance includes both additive and non-additive effects. Thus, the current study provides more evidence that the disease resistance against YVMV characteristic is controlled by a complex genetic inheritance pattern. The key genes for tolerance may be inherited by other okra crossings, but the virus strains that break tolerance may prevent them from maintaining tolerance over time. A persistent tolerance phenotype in okra may thus need the accumulation of additional genes.
