Variability among north carolina designs in okra (Abelmoschus esculentus (L.) Moench)

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 variability. The results of yield, plant height, number of nodes per plant, fruit girth and average number of fruits per plant was observed higher in NCD II for both the crosses. The value of CV was also higher in NCD II for yield, average number of fruits per plant and fruit weight in two cross. The test of significance between the means of progenies developed through North Carolina designs I, II and III for yield per plant, plant height, number of nodes per plant and intermodal length was observed significant in both cross. The average fruit length indicated significant difference in all the designs for both the crosses barring NCD I and NCD II in cross 1. The fruit girth was significantly higher in NCD II over NCD I in cross 1. The mean fruit weight was found more in NCD I for the cross 1 and NCD III for the cross 2. Early flowering was observed in NCD II for the cross 1 and it was significant with NCD I. The higher value of CV was observed in NCD II for the cross 1 and NCD III for the cross 2 for flowering.
