Abstract
The progenies developed through North Carolina Designs (NCD I, II and III) in F 2 populations of okra viz., HRB-55 x Kamini (cross 1) and BO-13 x Parbhani Kranti (cross 2) were used to study the genetic variances. The results indicated that none of the additive variances was found significant in NCD I in both the crosses. Additive gene action was observed for plant height, number of nodes/plant, inter-nodal length, fruit length, number of fruits/plant and average fruit weight in NCD II for both the crosses, and fruit length and average fruit weight for cross 1 in NCD III. None of the dominance variances was significant in NCD I and NCD III in both the crosses. Dominance gene action was important for fruit girth in both the crosses, for fruit yield in cross 1 and for fruit length in cross 2 in NCD II. Considering the significance, signs and SE of genetic variances, NCD II was found to be the most reliable matting design for the study of genetic variances among NC Designs. -------------------------------------------------------------------------------------------------------- Key words NCD I, NCD II, NCD III and Okra
