"The superiority of large seed is shown in the greater weight of 

 the edible portion of plants, approximately a 50 per cent increase; 

 and in the greater proportion of No. 1 plants, both in terms of num- 

 bers and weight. Forty per cent of the crop grown from large 

 seed was classified as No. 1, while only from 7 to 28 per cent of the 

 plants grown from small seed were thus classified. 



"After noting the relative productive capabilities of large and 

 small seed, it then seemed necessary to observe other factors in com- 

 paring the different-sized seeds. The following table displays data 

 as to variations in weight of seeds and number of plants produced, 

 together with the quality and weight of plants at the time of harvest.

"The large seed outweighed the small by 120 per cent; its 

 viability was better by 50 per cent; the crop from the same number 

 of seed grown was 117 per cent larger in terms of weights, 104 

 per cent larger in terms of numbers, 100 per cent greater in terms 

 of weight of edible roots, and the tops were 135 per cent heavier. 

 The total edible weight of the crop secured where small seed was 

 used was just 50 per cent of that harvested from the sowing of 

 large seed. 



"The studies noted above were followed by others at germination 

 time. Weights were made of the embryos during the first 5 days
