52818 to 52834. 



From Groningen, Netherlands. Seeds presented by C. Broekema, direc- 

 tor, Groninger Zaaizaadvereeniging. Received March 29, 1921. Quoted 

 notes by Mr. Broekema. Other notes adapted from Groninyer Zaaizaad- 

 vereeniging, January 5, 1921. 



52818 to 52822. Avena sativa L. Poaceie. Oats, 



52818. Gouden regen (golden drop)." 



Svalofs gouden regen. The grain is intense yellow and has a very 

 high weight per hectoliter. In some sandy districts this variety is 

 chosen above all others because it succeeds on poor soil. 



52819. "Mansholt 



This variety was obtained by Dr. Mansholt from a natural cross of 

 Deensche reuzenhaver (Danish giant oat). It makes a vigorous' 

 growth which sometimes lodges on very rich soil, but it is to be 

 recommended for fertile sandy soils. The grain is yellow, heavier 

 than that of Gouden regen, but the weight per hectoliter is not as 

 high. The husk is very thin. 



52820. " Mansholt II Br 



A variety introduced into the trade in 1912. which, because of its 

 excellent properties has'been extensively gi'own. The straw is fairly 

 stiff, and the yield in long slender grain is very good. In the better 

 soils it has become a competitor of the zegehaver. 



52821. "Zegehaver (Triumphal)." 



52822. " Zwarte President (Black President)." 



This variety has straw which is medium long and weak. The 

 yield on light soils is very good, but on heavy soil the yield is below 

 that of most of the white varieties. Its soil requirements are few. 

 and it ripens very early. The husk is thin, so that it is a first-class 

 feeding oat. 



52823 to 52825. Hordeum distichon palmella Harlan. Poacese. 



Barley. 



52823. ''Chevalier (Chevalier, spring variety)." 



A variety with a long narrow well-filled head. The grain yield is 

 good and the weight per hectoliter is very high. 

 For previous introduction, see S. P. I. No. 5842. 



52824. '*Goud (golden)." 



Svalofs goud. A variety with short, thin but strong straw, and 

 small, full, somewhat yellow grain. It is preferred above other 

 varieties by many growers and is extensively cultivated. 



52825. [No label.] 



52826 and 52827. Linum usitatissimum L. Linacese. Flax. 



52826. " Blawbloeilynzaad." 



Blue-flowered flax, the original seeds of which were imported from 

 Russia. 



52827. Withloeilynzaadr 



White-flowered flax. In the better flax districts this white-flowered 

 variety has been increasingly cultivated during the last few years 

 because it gives high yields of seeds and fiber. This form can better 

 withstand unfavorable weather and is less particular about soil 

 conditions.
