Abstract:
Ninety four (Indigenous and exotic) genotypes were tested in Augumented Block Design at Nidhariya Agriculture farm S.M.M. TOWN P.G. College Ballia during
Rabi 2017-18. The major objective was to study the correlation and path co-efficient analysis in wheat genotypes collected from different countries. The data were recorded on eleven quantitative traits namely days to 50% flowering, flag leaf area (cm
2), plant height (cm), spike length (cm), peduncle length (cm), tillers per plant, days to maturity, biological yield (g), harvest index, test weight (g) and grain yield/plant (g). The analysis of variance reviled highly significant differences between the genotypes under study. The data showed that the grain yield had significant and positive association with plant height (0.3820), peduncle length (0.7420), biological yield (0.9020), test weight (0.2711) and harvest index (0.5317)
. Path coefficient analysis revealed that maximum positive direct contribution toward yield by biological yield (0.8573) and harvest index. The results revealed that these traits may serve as effective selection attribute during selection in breeding program for yield improvement in wheat.
