Assessment of Genetic Diversity in Okra [Abelmoschus esculentus (L.) Moench]

Assessment of Growth, Flowering, Yield and Quality Parameters of Different Okra (Abelmoschus esculentus L.) Genotypes

“…The difference in leaf chlorophyll content (SPAD readings) of okra genotypes could be due to its specific genetic constitution regulating the nitrogen uptake and production of endogenous hormones like gibberellins and cytokines which helps to produce chloroplast, which contains chlorophyll pigment and act as site of photosynthesis (Lakshmipathi et al, 2017). The findings of the present study with respect to chlorophyll content are in agreement with the results of Morey et al [11], Kalemoge et al [5] and Mourya et al [12] in okra. Variation in days to 50 per cent flowering might be due to the variation in genetic potential, phenological and growth parameters of the genotypes which might be influenced by the additive × additive or additive × dominance or dominance × dominance gene action.…”

“…The increase in number of nodes per plant leads to increase in number of leaves and fruits per plant and leaf area per plant implies higher active photosynthetic area leading to higher production of biomass and yield. These results are in accordance with the findings of Morey et al [11], Kalemoge et al [5] and Mourya et al [12] in okra.…”

“…The significant difference in plant height among the genotypes could be due to the genetic setup and inheritance of the character as well as differences in apical dominance, cell division and cell elongation. The obtained results are in accordance with earlier findings of Saleem et al [4], Kelemage et al [5] in okra.…”

Genetic Variability Analysis for Traits in Okra (Abelmoschus esculents L. Moench) Genotypes

“…The variability of traits has more room for improvement and can thus be exploited for the development of superior genotypes. In this study, the results are coherent with those found by Yonas et al [16], Amoatey et al [30], Priyanka et al [31], Kelemoge et al [32], Olayiwola et al [33] and Rai et al [34], who have found significant differences in most traits in the tested okra genotypes.…”

“…Progeny selection or any modified selection procedure that exploits the additive effects of genes offers the best opportunity for improvement. This is in accord with Priyanka et al [31], Raval et al [41], and Sravanthi et al [44]. Although moderate heritability is associated with low GAM for days up to 50% flowering, this may be the result of favorable environmental conditions or nonadditive gene action rather than genetics.…”
