Synopsis

Research Paper (undergraduate) from the year 2014 in the subject Biology - Genetics / Gene Technology, Jawaharlal Nehru University (JNKVV Jabalpur MP), course: M.Sc. Ag. Horticulture Vegetable Science, language: English, abstract: The present investigation "Studies on genetic variability, heritability and genetic advance in okra [Abelmoschus sculentus (L.) Moench]" was carried out during kharif season of 2012-2013 at the Vegetable Research Farm, Department of Horticulture, College of Agriculture, J.N.K.V.V., Jabalpur (M.P.). The experimental material for the present investigation was comprised of 30 genotypes of okra. These genotypes were sown in Randomized Complete Block Design with three replications, to estimate the genetic variability. The estimates of mean sum of square due to genotypes were highly significant for all the characters, indicating the presence of genetic diversity in the existing material. The variation was highest for fruit yield per plant, followed by fruit yield per hectare, plant height at 120 DAS, plant height at 90 DAS, plant height at 60 DAS and fruiting span. High heritability coupled with high genetic advance as percentage of mean for traits like fruit yield per plant and fruit yield per plot suggested that the preponderance of additive genes. It also indicated higher response for selection of high yielding genotypes as these characters are governed by additive gene actions.
