Study on inter traits relationship among the parents and hybrids for seed yield and its contributing traits in fenugreek (Trigonella foenum- graecum L.)

The present investigation was carried out at Main Experiment Station, Department of Vegetable Science, Acharya Narendra Deva University of Agriculture \u0026 Technology, Kumarganj, Ayodhya (U.P.). The characters studied were Days to 50% flowering, Days to maturity, Plant height (cm), Number of branches per plantv, Pod length, Number of pod per plant, Number of seed per pod, Test weight (g), Biological yield (g), Harvest index (%) and Harvest index (%). At phenotypic level seed yield per plant exhibited positively significant correlation with harvest index (0.825), Number of pods per plant (0.921), days to maturity (0.374), Number of branches per plant (0.281), plant height (0.338) and pod length (0.287). Harvest index exhibited positively significant correlation with test weight (0.483), number of pod per plant (0.750), plant height (0.412) and days to maturity (0.339). Harvest index was also showed negatively significant correlation with biological yield per plant (-0.618). Biological yield per plant exhibited positively significant correlation with number of branches per plant (0.403), number of seed per pod (0.341) and showed negatively significant correlation with test weight (-0.501) and plant height (-0.271). Test weight showed negatively significant correlation with days to 50% flowering (0.629) and days to maturity (0.406). Number of seeds per pod (0.698).Number of pod per plant was exhibited positively significant correlation with number of branches per plant (0.295), plant height (0.289) and days to maturity (0.304). exhibited positively significant correlation with days to 50% flowering (0.560). At the genotypic level in general the correlation coefficient were similar in nature but higher in magnitude to that of observed value at phenotypic level. Here also seed yield per plant showed highly significant and positive correlation with harvest index, days to maturity, test weight, plant height, pods length and number of branches per plants. Other combinations of different pair of characters showed association as at phenotypic level during E1, E2 and pooled. However as seed yield per plant showed highly significant and negative correlation with biological yield.
