Correlation and Path Co-Efficient Studies In 150 Fenugreek Genotypes (Trigonella foenum-graecum L.)

Abstract

Fenugreek [Trigonella foenum-graecum L.] is an annual herb and is largely cultivated in warm temperate and tropical regions. The analysis of genotypic as well as phenotypic correlations showed that the yield per plant had significant and positive association with plant height, primary branches per plant, secondary branches per plant, pod length, pods per axis, pods per plant, seeds per pod and test weight. The trait days to 50 per cent flowering showed significant negative correlation and days to 75 per cent maturity showed non-significant positive correlation with the yield per plant. Path co-efficient analysis revealed that high positive direct effects were exerted by traits like primary branches per plant, secondary branches per plant, pods per plant, seeds per pod and test weight. And plant height exerted moderate positive direct effect, on yield per plant. This suggests that these traits directly contribute towards yield per plant. So, importance is given for these traits during crop improvement programme to increase yield per plant.
