| Abstract: | This paper deals with the genetic variation in twelve quantitative characters related to fibre yield, fibre quality and days to harvest in fifty-four local jute varieties from five southern provinces of China. According to the estimated phenotypic and genotypic variance and covariance, the genetic potential of all the quantitative characters has been calculated and their genetic variation, selection potential, expected efficiency, phenotypic and genotypic correlation and their comparative importance to fibre yield are analysed. The analyses of phynotypic and genotypic pathway indicate that branching height from base to point of branching and fresh bark thickness are the main constituents of dry bark weight and fibre weight per plant. |
