ABSTRACT

Kenaf is a fast-growing plant of the Malvaceae family. It is also known for its bast fiber. An experiment was conducted with twenty-five kenaf genotypes with geographic origins at the central jute agricultural experiment station of Bangladesh Jute Research Institute (BJRI), Jagir, Manikganj using randomized complete block design with three replications to assess the genetic diversity of various morphological characters. Multivariate analyses were performed for this purpose. Twenty-five kenaf genotypes were grouped into five clusters while cluster II comprises maximum 7 genotypes followed by 5 genotypes in clusters III, IV, and cluster V. The first principal axis, plant height (m), accounted for the majority of the variation among genotypes, accounting for 74.07% of the total variation. The highest fiber weight was recorded by cluster V (19.00) while cluster I (10.33) showed the least fiber weight. The maximum and minimum inter-cluster distances were observed between clusters I and V (13.566) and I and III (2.602), respectively. Cluster I had the greatest intra-cluster distance (0.518), while Cluster V had the smallest (0.092). The inter-cluster distances were larger than the intra-cluster distances. Green bark thickness contributed maximum towards total divergence. The genotypes of clusters I (G5, G11, G12) and V (G1, G2, G22, G24, G25) were more diverse as they could be used as parents for future breeding programs. Recombination is enabled by genetic diversity, which is required for varietal development. Considering cluster distance, inter-genotypic distances G22 and G25 might be suggested for future breeding programs.
