Studies on Variability in Certain Intervarietal Crosses of Okra [Abelmoschus esculentus (L.) Moench]

A field experiment was conducted to study the genetic variability, heritability and genetic advance of seven characters namely, days of first flower, plant height, number of nodes per plant, number of fruits per plant, fruit length, single fruit weight and fruit yield per plant in the segregating generations of crosses Arka Anamika x MDU 1 and Parbhani Kranti x MDU 1. For fruit yield per plant in all the crosses, the variability in F₂ generation in general were high when compared to F₃ generation. High PCV and GCV were observed in all three crosses for number of nodes per plant, number of fruits per plant and single fruit weight. The traits single fruit weight and fruit yield per plant showed high heritability along with high genetic advance in all the crosses which indicated that is might be due to the predominance of additive gene effects.
