Multivariate Analysis of Quantitative Characters Variation in Jute (Corchorusolitorius L.)

Fourteen morpho-agronomic traits of 30 jute genotypes, including 2 standard varieties of Corchorus olitorius L. were evaluated to assess the extent and patterns of variability. Principal component (PC) analysis revealed that the first four PCs having Eigen values >1 explained 73.0% of total varia...

Summary:Fourteen morpho-agronomic traits of 30 jute genotypes, including 2 standard varieties of Corchorus olitorius L. were evaluated to assess the extent and patterns of variability. Principal component (PC) analysis revealed that the first four PCs having Eigen values >1 explained 73.0% of total variation. The variance explained by PCI was mostly due to traits related to fibre yield, whereas PC2 was mostly related to bark thickness. Two-dimensional scatter plot supported the grouping patterns of cluster analysis. The accessions OEX 024, OIN 250, OEX 015, OIN 271, OIN 997, and OEX 027 of C. olitorius were identified as the most diverse genotypes, based on component scores for use as parents in hybridization program.
