Correlation and Path Coefficient Analysis in Wheat (Triticum aestivum L.)

The present investigation was conducted by taking 137 genotype of bread wheat with 4 checks in Randomize Block Design for the study of correlation and path coefficient analysis. The observations were recorded on 13 quantitative characters. The grain yield per plant exhibited highly significant and positive correlation with biological yield per plant (0.31) followed by harvest index (0.18) and 1000-grain weight (0.11). The highest positive direct effect on grain yield per plant was exerted by biological yield per plant (0.30) followed by 1000-grain weight (0.16), harvest-index (0.13), tillers per plant (0.10), grains per spike (0.08), days to maturity (0.02) and peduncle length (0.01). Thus, biological yield per plant, harvest index and 1000-grain weight can be utilized for selection of elite genotypes with better grain yield.
