Abstract:
Twenty five genotypes of Kenaf (Hibiscus cannabinus L.) from different
geographic origins were grown at the Central Jute Agricultural Experiment station
of Bangladesh Jute Research Institute (BJRI), Jagir, Manikganj during 15 March
to 30 September, 2015 to study their variability, correlation and diversity for nine
morphological characters. Significant variation was found for all the characters
among the genotypes. PCV was greater than GCV and high GCV values were
observed for green weight with leaves, green weight without leaves, stick weight
and fibre weight. The high heritability (more than 85%) coupled with high genetic
advance in percent of mean were observed for most of the traits. All the characters
except green bark thickness and internode length showed significant and positive
correlation with fibre weight. Path co-efficient analysis revealed that green weight
with leaves, green weight without leaves, green bark thickness and stick weight
showed positive direct effect on fibre yield. The maximum and minimum cluster
distance were observed between clusters I and V (13.566) and I and III (2.602),
respectively. Plant height was found responsible for the maximum diversity. The
genotypes of clusters I and V were more diversed as they could be used as parents
for future breeding program to develop Kenaf variety. Considering cluster distance
and other agronomic performance genotypes G22 and G25 might be suggested for
future hybridization program.
