Abstract
India is home of vast agro-ecological diversification.
A good amount of information is available on correlation and path analysis in fenugreek for seed purpose.
In India, a wide range of genetic variation is found in fenugreek leaves, leaf size, number of root nodules, branching and flavour.
Information related to correlation and direct and indirect effect of such characters to foliage yield and seed yield would add advantage in selection criteria of fenugreek.
Genetic diversity of fenugreek in India provides a vast opportunity to exploit its potential.
So, the present study was planned to reveal the nature and magnitude of correlation among different characters in fenugreek.
Association studies in fenugreek revealed that fresh weight plant‑1 had a highly significant and positive relationship with all quantitative characters except the number of branches plant‑1, dry weight plant‑1 suggesting that major emphasis should be given on these characters for improving yield for leaf purpose.
Path coefficient analysis in fenugreek at horticultural maturity revealed that root length had the highest positive direct effect on fresh weight plant-1 followed by total chlorophyll content, plant height, number of root nodules plant‑1, dry weight plant‑1, average weight of root and leaf area.
The association studies for various characters noted a mutual relationship among the traits that contribute to the leaf yield of fenugreek.
It was suggested to consider these characters while selecting desirable accessions for improving a high yielding cultivar of fenugreek.
