Abstract:

The research work was conducted at the BCKV, research station in Mohanpur, Nadia, West Bengal in 2020, thirty jute genotypes were evaluated for fibre yield and related traits. It was revealed that 14 yield-related characters, such as basal diameter, bark thickness after 120 DAS, plant height, green weight plant^-1, node number plant^-1, and internodes length, showed moderate genetic advance and high heritability. These traits were found to be significantly different. Plant height, node number plant^-1, internode length, basal diameter, petiole length, leaf area, bark thickness, green weight plant^-1, chlorophylls 'a' and 'b', and total chlorophyll, as well as dry stick weight plant^-1, all displayed a significantly positive correlation with dry fibre weight at both the phenotypic and genotypic levels. The path coefficient analysis results showed that node number plant^-1, internode length, plant height, basal diameter, petiole length, bark thickness both at 90 DAS and 120 DAS, chlorophyll 'b' and total chlorophyll had significant direct effects on dry fibre yield. These characters should be taken into consideration as important selection criteria to increase the yield of fibre in tossa jute.
