VARIABILITY AND PATH COEFFICIENT ANALYSIS IN JUTE (corchorus olitorius L.) OF INDIGENOUS ORIGIN

Abstract

Forty one indigenous genotypes of tossa jute (('orclzorus oli/orious) including three commercially cultivated varieties as cheeks were evaluated to study their vax-lability, correlation and path coefficient analysis with 09 different morphological characters at the Central Jute Agricultural Fxperiment Station, Jagir. Manikganj of Bangladesh Jute Research Institute (BJRI) during April to September 2007. Significant variation was observed among the genotypes tested in respect of plant height, base diameter. number of nodes per plant, leaf area. green weight with leaves per plant. green weight without leaves per plant. stick weight per plant and fibre weight per plant except internode length. Considering genetic parameters high Cienotypic Coefficient of Variation (CCV) values were observed for green weight without leaves per plant Ibilowed by stick weight per plant, green weight with leaves per plant and fibre weight per plant. high heritability values with high genetic advance in percentage of mean were obtained fhr stick weight per plant, green weight with leaves per plant, green weight without leaves per plant and fibre weight per plant. All the genotypes showed maximum growth rate from 90 to 105 days of emergence. Correlation study revealed positive sigsuilicant association of fibre yield with all the characters at genotypic level, except plant height and green weight with leaves per plant. At phenotypie level, green weight with leaves per plant, green weight without leaves per plant and stick weight per plant showed significant positive relationship with fibre yield. Path coefficient analysis indicated maximum direct contribution of stick weight per plant towards fibre yield followed by internode length, green weight without leaves per plant, plant height and green weight with leaves per plant. Genotypes, 01 and 3j3 showed better yield performance indicating the possibility of using them in future breeding programme.
