| Summary Simple correlations and path coefficients were worked out in a collection of eleven wheat varieties. The study of path coefficients revealing the direct and indirect effects showed that 100-grain weight was the most important character influencing yield followed by the ears per plant. This analysis also very clearly showed that only the simple correlations were not sufficient to formulate appropriate selection procedures. Literature cited DEWERY, D. R. and K. H. Lu 1959.
