“…The natural transmission of the disease occurs through whitefly [6]. In our previous study we observed that okra plants either expressed YVMV or ELCV symptoms, but not both, in a population [7]. The important symptoms of this disease are curling of leaves in an adaxial direction, and mild or bold enations on the under surface of the leaves which become thick and deformed.…”

Among the viral diseases, enation leaf curl virus (ELCV) has now becoming a menace in okra cultivation particularly in the tropics. Okra parents and hybrids tolerant to ELCV disease were selected based on estimates of combining ability and heterobeltiosis in the Gangetic plains of West Bengal, the most productive okra growing zones in eastern India. Eight diverse lines were crossed in diallel fashion without reciprocals to obtain 28 F 1 s. Additive genetic control of ELCV disease severity suggested use of pure line selection in the advanced generations from the highly heterotic crosses could be the best possible method to improvement of this trait. Two parents 285-1-3A-1-17-1 and VRO-178 with good general combining ability effects for tolerance to ELCV disease can now be used in future breeding programme. Partial-to over-dominance reactions for the inheritance of studied traits were recorded. We could able to isolate two outstanding hybrids 285-1-5-1-16-23 × VRO-178 and 285-1-3-1-15-2-1 × VRO-178 based on fruit yield and ELCV disease tolerance under field and epiphytotic conditions, and they could be commercially exploited after critical evaluations. Our study also suggests that either the identified donor parents will be used to develop backcross populations or exploiting promising hybrids in segregating populations for generating new inbred lines with much higher levels of tolerance to ELCV disease in okra.

“…In India, YVMV disease is the major production constraint for okra causing yield loss between 50% and 94% depending on the stage of crop growth at which infection occurs (Sastry & Singh, 1974;Venkataravanappa et al, 2013). There is no reliable source of resistance for YVMV among the genotypes of cultivated okra, which necessitated the use of some wild relatives as the source of resistance (Dhankhar & Koundinya, 2020;Sanwal et al, 2016;Yadav et al, 2018) although different challenges experienced during introgression of resistant genes from the wild relatives include poor cross-compatibility, hybrid sterility and linkage drag of undesirable characteristics from the wild species (Singh, 2017). Mutation breeding emerges as a feasible alternative to isolate desirable and utilizable mutants from the variation induced in the M 2 and subsequent generations without altering the overall superior base of the cultivated variety (Khursheed et al, 2016).…”

Okra, Abelmoschus esculentus (L.) Moench, being highly susceptible to yellow vein mosaic virus (YVMV) disease warrants its genetic improvement for resistance. Applied mutagenesis programme using two optimum doses of gamma radiation, namely, 350 Gy and 450 Gy radiation, was administered for the variety Pusa Sawani rated as excellent for fruit quality but highly susceptible to YVMV disease. Two selected putative mutant families, namely, 350//10///3‐9////28 and 450//66///2‐4////39, isolated in the M5 generation with slightly different plant morphology as compared to the parental genotype, Pusa Sawani, showed consistent resistance against YVMV disease. Upon evaluation in the M6 generation, eight morphological characteristics and five quantitative characteristics differed significantly among the mutants and Pusa Sawani. Proximate compositions and enzyme activity in leaf were significantly higher in the two YVMV‐resistant mutants. Disease screening under artificial inoculation in the insect proof cages confirmed YVMV resistance in these mutants. DNA fingerprinting further validated the alterations occurred in these two isolated mutants compared to the parental genotype. These mutants deserve due attention towards the development of YVMV‐resistant variety.
