Rank correlation of seed and Fibre Yield Characters in Jute (Corchorus olitorius)

Abstract

The present study aimed to explore the Rank correlation of seed and fibre yield characters in Jute (Corchorus olitorius). Jute cultivation availability of quality seed remains a potential factor as it deals with the fibre. Studying the correlation between both seed and fibre characters at the same time in jute is a complex matter since the sowing season, agricultural practices vary in both the cases. Varieties producing high fibre and seed yield are necessary to meet the deficit in seed supply for the jute producing farmers of West Bengal, India. In this study, the experimental material consisted of thirty six jute (Corchorus olitorius L) crosses along with two check varieties. Fibres were harvested at 120 days and the seeds at maturity. The variability in most of the yield (fibre and seed) contributing characters was mainly due to genotype with some extent of environmental influence. To obtain a clear understanding of the inter-relationship between seed and fibre characters a rank correlation was performed instead of simple correlation.  A strong positive correlation was found which helped us in finding lines with both high seed and fibre yield. Furthermore, a fibre quality test was also conducted for estimating the fineness and strength of the fibre.
