The annual yields of barley in varietal experiments at the Tennessee Agricultural 
Experiment Station, Knoxville, furnished through the courtesy of this station, 
are presented in Table 88. While the plat experiments have not been so exten- 
sive here as at some of the other southern stations, much work has been done 
in breeding and selecting winter varieties for general cultivation in the warm 
and humid regions of the South. Tennessee undoubtedly has the largest winter- 
barley acreage of any humid State. The parent stock of Tennessee Winter 
(C. I. No. 257) has been the common barley in this region. This variety, 
as improved by mass selection at this station, was first distributed about 1900 
as "Tennessee Winter.'' Several hooded hybrids which seem promising as 
■winter barleys have been developed and distributed to other stations and to 
farmers. 
Table 88 shows that Union Winter (C. I. No. 583), a barley of the Tennessee 
Winter group, is the only variety grown during the full period of the experiment. 
Tennessee Winter (C. I. No. 257), hovrever, was grown for 11 of the 14 years, 
so that a fair comparison of the j-ields of the two varieties can be made. Union 
Winter undoubtedly is the higher yielding of the two at this station for this period. 
It produced an average acre yield of 42.8 bushels, as compared with 39.9 bushels 
for Tennessee Winter. In general appearance these varieties are quite similar, 
although Union Yv'inter is a few inches shorter and several days earher than 
Tennessee Winter. 
Four varieties were introduced in 1908. Of these, Tenarab (C. I. No. 662) 
was the only one that was further tested, being grown in 1910 and 1911. In all 
of the three years it was inferior to both Union Winter and Tennessee Winter. 
Maryland Winter (C. I. No. 518) yielded 65.2 bushels in 1908, which was the 
highest that year. Bestehorn Giant (C. I. No. 414) and Black Winter (C. I. 
No. 337) were both quite inferior to the other four varieties. Beardless 20 
(C. I. No. 2745), grown in 1913, 1914, 1916, and 1920, and Beardless 6 (C. I. 
No. 2746), grown in 1920 and 1921, are hooded selections made from a number 
of hybrids between Tennessee Winter X Horsford and I nion Winter X Horsford. 
According to C. A. Mooers, of this station. Beardless 20 has been distributed to 
some of the farmers in the vicinity and is being more extensively cultivated. 
On poor or average land it produces nearly as much grain as L'nion Winter, with 
a larger yield of hay of superior quality. It does not stand wet-land conditions 
well, however. Beardless 6, although inferior to Beardless 20 in 1920, according 
to Professor INIooers, is "more robust and has greater capacity to produce both 
grain and straw. It also stands wet-land conditions weU." Neither of these 
varieties was the equal of Union Winter or Tennessee Winter at this station in 
the years when comiparable yields were obtained.

It is evident from these results and from the types in general cultivation that 
the Tennessee Winter barleys are well adapted to growing conditions in Tennessee. 
While the hooded hybrids developed here are recommended especially for hay
