Genetic Diversity in Okra (Abelmoschus esculentus L.) Genotypes with Various Quantitative Traits

Abstract

An experiment was conducted at Horticulture Research Centre, Sardar Vallabhbhai Patel University of Agriculture & Technology, Meerut, India-250110. The analysis of variance data revealed substantial genetic differences for all morphological traits. According to Mahalanobis D2 all the forty genotypes were found to have a significant amount of genetic diversity. The result indicated that the greatest mean value was found in cluster III for days to 50 per cent flowering, days to Ist flower initiation, days to Ist fruit set, days to Ist fruit picking, days to IInd fruit picking, number of primary branches, number of nodes / plant, duration of crop and also some characters was found highest mean value in cluster I like, plant height, fruit length, number of fruits / plant, length of internode, fruit yield / plant and fruit yield (q/ha.). Cluster II had the most genotypes recorded overall. (21 genotypes) followed by 11 genotypes in cluster I. The largest intra cluster distance was discovered in cluster III, whereas the largest inter cluster D2 distance was measured between Cluster I and Cluster III. The genotypes of Cluster I and Cluster III are not closely related, according to the maximum inter-cluster D2 distance, although the genotypes of Cluster I and Cluster II are, according to the minimum inter-cluster D2 distance. Among all the characters that were contributed, the length of internode had the highest contribution %.
