For average weight of kernels per plant correlated with average number 

 of kernels per culm of plant (Figs. 110 to 113), the highest coefficient is 

 .524 ± .028 for series 1200, and the lowest is .340 ± .034 for series 1219. 

 The difference here is .184 ± .044, which is a little more than four times 

 its probable error.
