Variation and Correlation of Oats — Part I 69 



7. The average kernel weight is not correlated closely and consistently 

 with any other character here considered, except average culm jdeld, 

 with which the correlation is fairlj^ high and fairly consistent. 



8. The average number of spikelets per culm per plant is correlated 



(a) fairly highly with the average number of kernels per spikelet; (b) appar- 

 ently very highly with number of kernels per culm; (c) very highl}^ and 

 stably vnth average height of plant and total jdeld; and (d) in a fluctuating 

 manner with kernel weight. 



9. The correlations between number of culms per plant and (a) height, 



(b) culm yield, (c) number of kernels, are fluctuating, varying greatly 

 from high to low; between number of culms per plant and (d) total yield 

 they are high, positive, and stable; between number of culms per plant and 

 (e) average kernel weight they are fairly stable and always low.
