NAKED KERNELS OF BURT OATS AND HULL-LESS OATS 



Figure 19 The grains of hull-less oats (top) are somewhat smaller and lighter in color 

 than naked seeds of the Burt variation (bottom). The cause of the mu tiflorous variation

articulation, having no basal scar or 

 basal pubescence. It had a brown 

 glume and a weak awn. This kernel, 

 along with several thousand others, 

 was sown at Akron, Colo., April 29, 

 1920. The plant headed June 21, 

 which was five days earlier than the 

 average for the parent strain. Of 

 227 plants of this strain of Burt, but 

 ten reached the heading stage before 

 June 21. With the exception of the 

 panicle, the characters of the plant 

 did not vary greatly from the average 

 of the parental strain. 



Experimental Data 



In 1921, kernels from the variant 

 were sown at the Akron Field Sta- 

 tion and at the Kansas Agricultural 

 Experiment Station. Several unfavor- 

 able factors influenced the results ob- 

 tained at the two stations. Weather 

 conditions at Akron in 1921 were very 

 adverse, and as a result of dry weather 

 and the ravages of locusts but forty- 

 three plants were grown to maturity 

 from a total of eighty-one kernels 

 sown. The plants at the Kansas sta- 

 tion fared little better, injury by chinch
