A Correlation and Path‐Coefficient Analysis of Components of Crested Wheatgrass Seed Production 1

Douglas R. Dewey, Kai Lu

Open publisher page 2,291 citations

Abstract

Synopsis Fertility and plant size were the most important components of seed yield. Inasmuch as fertility and plant size were negatively correlated, r = −.665, a compromise must be reached in selection for these two characters if maximum seed yields are to be obtained. The method of “path coefficients” proved useful in analyzing correlation coefficients in this system of interrelated variables.
