Abstract

This study investigates the relationship among morphological parameters and with seed yield for 167 fenugreek accessions including two checks (Methi and Methray) under field at (NARC) Islamabad Pakistan. Augmented field design was used. An inter row distance was kept at 45cm and intra row distance was 1m. The results revealed that there was positive and significant correlation of seed yield with leaf length, days to maturity, days to flower completion. These characters might be enhanced instantaneously and given earlier stress for indirect selection of high yielding fenugreek accessions. PCA analysis showed that the presence of genetic diversity among the valued germplasms. Four out of the 21 principal components with an eigenvalue of ≥ 1.0 accounted for 53.37% of the overall differences found among 167 genotypes of fenugreek. Contribution of the first three PCs were 20.07%, 12.29% and 11.29%, accessions indicating that these accessions may be used in breeding programs for obtaining promising lines. The presence of considerable genetic differences, and highly significant, positive interrelated parameters can be utilized in breeding programmes for development of new fenugreek cultivars.
