Variation and Correlation of Oats — Part II 



185 



For average yield of culm per plant and diameter of straw (Figs. 157 

 to 162), the correlation is highest in the medium condition of crowding, 

 and lowest in the least condition of crowding, for both lines.. In 

 line 50 the highest and the lowest are .882 ± .009 and .765 ± .018,
