VARIABILITY IN MORPHOLOGICAL AND ANATOMICAL CHARACTERS AND THEIR ASSOCIATION IN WILD JUTE (corchorus species)

Abstract

Six wild corcizorus species collected from different geographic origins were evaluated to study their variability, correlation and palh coefficient analysis with 16 morphological and S anatomical characters at Bangladesh Jute Research Institute. Dhaka, during April to December. 2004. Significant variations were observed among the species tested. Considering genetic parameters. high GC'V values were observed for plant height, internode length, leaf area. number of branch per plant. number of node per plant, green weight with leaves, green weight without leaves, dry fibre weight, dry slick weight, number of' fruits per plant. number of seeds per fruit, root length and all anatomical characters. I ligh heritability values with high genetic advance in percentage of means were observed For root length. plant height. inter node length, leaf area, number of branch per plant, number of node per plant, green weight with leaves, green weight without leaves. dry fibre weight. dry suck weight, number of fruits per plant, number of seeds per fruit and all anatomical characters. The fibre yield showed strong significant positive correlations with plant height. base diameter, middle diameter. number of node per plant, fresh weight with leaves, fresh weight without leaves, number of fruits per plant, dry stick weight, bark thickness. VII number of Fibre bundle per TS. number are per layer, number of pyramid per IS, ultimate fibre cell length both at phenotypic and genotypic levels. Path coefficient analysis indicated maximum direct contribution towards dry fibre weight through bark thickness followed by thy stick weight, plant height, ultimate fibre cell length, number of node per plant, root length, top diameter, middle diameter, L/B ratio, inter node length, number of fibre bundle per TS. branch per plant both at phenotypie and genotypic levels.
