In connection with extensive variety tests which Mr. Thomas 
was conducting on field peas for forage purposes at La Jara, we 
have had an excellent opportunity to observe disease resistance to 
the bacterial blight. Out of the 48 varieties which we examined, 
there were 8 desirable varieties from a forage standpoint that 
showed any appreciable degree of resistance. Almost without ex¬ 
ception, the best forage peas were the worst affected by the disease. 
The results of our observations on disease resistance are given in 
Table VII. The peas were planted May 3, 1915, and observed 
June 17, 1915. 
Brief descriptions of the forage qualities of the different peas 
follow : 
OBSERVATIONS MADE AT LA JARA, COLORADO, AT TIME OP 
HARVEST, BY E. H. THOMAS, COUNTY AGENT 
All varieties planted under same conditions and at same time; 
four fifty-foot rows of each. Planted May 3, 1915. Seed fur¬ 
nished by Bureau of Forage Crop Investigations and by experiment 
stations of Idaho, Washington, Oregon, Minnesota and Ontario. 
Some varieties were also furnished by the W. A. Davis Seed Com¬ 
pany, and the Allen Seed Company. Some seed was purchased 
from points in the north and west. 
NO. 11087.— EUGENE. —Produced slender short vine at La 
Jara. Yield of forage fairly heavy, with many well-filled pods. 
Should be excellent pea seed for heavy land, fairly early maturing. 
\ 
NO. 16130.— GOLDEN VINE. —Produced a tall, medium-sized 
vine; fairly good quantity of forage, but with few pods and they 
were poorly matured. Alight make good if planted early in light 
soil. 
NO. 16436.— GREY WINTER. —Produced medium length, small- 
sized vine. Produced good quantity forage. Was extremely well 
podded but rather immature. Believe that peas should be sown 
probably on heavy or medium heavy soil late in fall or very early 
spring. 
NO. 18455.— SHANGHAI.— Produced medium length, slender 
vine. Yielded fair amount of forage. Many medium-sized pods 
containing rather hard, medium-sized peas which shatter rather 
easily. WYuld no doubt make good forage or grazing pea on 
fairly strong land. Medium late. 
NO. 19788.— POTTER. —Produced long coarse vine. Good 
amount forage. Yielded fair number pods, but poorly matured. 
Would probably make excellent forage pea on medium or heavy 
soil. Should be sown very early in spring.
