Average yield of culm per plant is correlated with average weight of 

 straw per culm of plant (Figs. 169 to 174) in line 50 as follows: .901 ± 

 .007 in series 122; .919 ± .007 in series 63; and .941 ± .004 in series 100. 

 The difference of the extremes is here .040 ± .008, which is not highly
