CORRELATION AND PATH COEFFICIENT ANALYSIS OF YIELD IN WHEAT: A REVIEW

A comprehensive study in grain yield potential is crucial in the selection among wheat genotypes. Grain weight alone doesn’t decide the portion of economic yield in a harvest index as grain yield is the subtractions of many yield components. Information of associations among traits and yield implies their relative importance for selection in yield improvement. Correlation study is a widely used measure to determine the degree of relationship between various traits. The path analysis is a powerful measure which partitions the correlation coefficient and deals with the relative importance of yield contributing traits on yield. The correlation and path coefficient analysis of grain yield in wheat is reviewed in the paper.
