The Study of Variability Heritability and Genetic Advance in Okra [(Abelmoschus esculentus L.) Moench] Crop

Abstract

The study was conducted during kharif 2019 to Ziad 2020  at the research farm of shri Durga ji post graduate college Chaneshwar Azamgarh U.P. with ten genotypes Azad Bhindi1, Azad Bhindi 2, Azad Bhindi 3, KS 312, VRO5, KS 442, KS 439, BO2, Arka Abhay and Prabhani Kranti along with 11 characters viz days to flowering,  height of plant, number of branches per plant /main shoot, number of first fruiting node, height of first fruiting node, number of nodes per plant, length of internodes, length of fruit, width of fruits  , number of fruits per plant and fruit yield per plant .  All data recorded as per scientific for good genotypes of releasing factors i.e. high yielding and good quality characters. The number of first fruiting node coefficients of variability  for all the variables traits were higher in F1 generations. The number of initial fruiting nodes and total number of nodes in the F1 generation exhibited coefficients of variability with highest magnitudes in the F1 generation. When compared to parents, F1 generations, and other traits, the number of branches per plant showed the highest coefficient of variabilities in F2. The high heritability estimates in narrow sense were observed for length of fruit in both the generations and height for all the characters except height of plant, width of fruit, number of fruits per plant and fruit yield per plant in F1 generation only. Other characters showed moderate heritability F2 generations and height of plant in both generation, genetic advance in narrow sense higher in F2 then F1 generation for all the characters. The maximum genetic advance was observed for fruit yield per plant in F1 and F2 and moderate genetic advance was observed for height of plant in both F1 and F2 generation.
