Genetic variability and performance of Tossa jute (Corchorus olitorius L.)

Genetic variability, genetic performance and correlation coefficients for yield and its components of 4 exotic varieties along with 5 strains/varieties of Bangladesh Jute Research Institute were studied. The estimates of variance for all the characters showed significant differences among the nine genotypes. The improved variety 0-9897 of BJRI gave the highest plant height, base diameter, green weight, stick weight and fibre weight. The genotypic and phenotypic coefficient of variation, heritability and genetic advance were observed for fibre yield. Fibre weight showed positive significant correlation with plant height (r=0.95), base diameter (r=0.92), green weight (r=0.98) and stick weight (r=0.93).
