Abstract: Wheat (Triticum aestivum L.) is an important cereal crop of cool climates, and plays a key role in the food and nutritional security of India.The present investigation was aimed to establish the inter-relationship and direct and indirect effect of various yield components of wheat. An evaluation of 72 accessions of wheat germplasm for yield as well as quality traits in an augmented design revealed highly significant differences among the accessions for test weight, biological yield per plant, plant height and days to 50% flowering in case of block whereas the variation due to check were found highly significant for most of the characters. The genotypes exhibited higher grain yield were 4th STEMRRSN 6110, 20th HRWSN 2081, 43IBWSN 1034, 4th STEMRRSN 6116 and 20th HRWSN 2049. Economic yield per plant were showed highly significant and positive association with biological yield per plant, effective tillers/plant, plant height and flag leaf area whereas it had been found to be significant and positive with grains per spike. Path analysis identified biological yield per plant followed by peduncle length and effective tillers per plant showed as major positive direct contributors towards expression of economic yield per plant. Whereas, days to maturity, vigour index and harvest index had negative direct effect on economic yield per plant.
