Fig. 89. — Correlation between average yield of culm per plant, in deci- 

 grams, subject; and average height of plant, in centimeters, relative. 

 Sixty Day r=. 875 ±.009 



When average yield of culm per plant is correlated with average number 

 of kernels per culm of plant (Figs. 90 to 93) , the difference in the coefficients 

 is slightly greater. The highest, .985 ± .001 for series 1238, is .051 ± 

 .005 higher than the lowest, .934 ± .005 for series 1219. This extreme 

 difference, although small, is more than ten times its probable error.
