“…Chaturvedi et al [9] reported that the reduction in dry weight is associated with the suppression of cell expansion and cell growth due to lower turgor pressure that occurs when plants are experiencing water shortages. Another record of reduced plant dry weight under drought stress was reported by Komolafe et al [3]. Significant (p < 0.05) genotypic differences were recorded for NPPP under DS conditions.…”

“…Under drought stress conditions, okra plants can accumulate sufficient photo-assimilates, resulting in higher YPPP [9]. In addition, Komolafe et al [3], reported that pod yield could be improved with selection of a higher number of pods per plant and heavier pods as breeding parents. Genotypes LS19, LS20, and LS25 recorded the lowest PYPP (<1 g) under DS conditions.…”

“…However, varying levels of cross-pollination have also been reported depending on the activity of insect pollinators and the growing environment [1]. The tender green pod is the most economical and vital source of vitamins A, B 1 , B 3 , B 6 , folic acid, C, and K, essential for the human diet [3]. Potassium, magnesium, phosphorus, and calcium are the principal and essential mineral elements present in the green and immature pods of okra [4].…”

Genetic diversity analysis of crop genetic resources is a prerequisite for parental selection with suitable and complementary profiles for breeding. The objectives of this study were to determine genetic diversity present among okra accessions using simple sequence repeat (SSR) and complementary phenotypic markers and to select genetically divergent and superior parental accessions for pre-breeding. Twenty-six preliminarily selected okra accessions were assessed using nine highly polymorphic SSR markers and phenotyped under drought-stressed (DS) and non-stressed (NS) environmental conditions using a 13 × 2 alpha lattice design with two replications. Data were collected on the following eleven phenotypic traits: plant height (PH), days to 50% maturity (DTM), fresh pod length (FPL), dry pod weight (DPW), dry pod length (DPL), number of pods per plant (NPPP), pod yield per plant (PYPP), total above-ground biomass (AGB), harvest index (HI), root weight (RW), and root to shoot ratio (RSR). The SSR markers revealed an expected mean heterozygosity value of 0.54, indicating moderate genetic diversity among the tested okra accessions. Cluster analysis based on phenotypic and SSR markers differentiated the accessions into three distinct genetic groups. Wide phenotypic variation was observed for PH, FPL, NPPP, and PYPP under NS and DS conditions. PYPP was positively and significantly correlated with FPL (r = 0.81), ABG (r = 0.69), and HI (r = 0.67) under DS conditions, and FPL (r = 0.83) and AGB (r = 0.60) under NS conditions. Genetically complementary accessions such as LS04, LS05, LS06, LS07, LS08, LS10, LS11, LS15, LS18, LS23, LS24, and LS26 were identified for their high yield potential and related yield-improving traits under DS conditions. The identified accessions are recommended as parents for hybridization and selection programs to improve the yield potential of okra under drought-stressed environments.

“…The genotypes had long petioles, which might serve as an important character for yield improvement in okra (Mishra & Hugar, 2021) registering significant positive correlation with yield (Komolafe et al, 2021;Yadav et al, 2020). The colour traits, namely, stem colour, colour between veins and pigmentation in petiole, are not easy to assess due to uncertainties with colour variations (Reddy et al, 2016).…”

“…Deeply lobed leaf shape confers resistance/non‐preference to the whitefly in okra (Reddy et al, 2016) by virtue of greater leaf perimeters to area ratios resulting in higher ambient temperature and lower humidity surrounding the canopy. The genotypes had long petioles, which might serve as an important character for yield improvement in okra (Mishra & Hugar, 2021) registering significant positive correlation with yield (Komolafe et al, 2021; Yadav et al, 2020).

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.
