N. Dak. Fat Acid Composition of Linseed Oil from the World Col- 

 lection of Flax Varieties . Find a flax variety producing a 

 quick drying oil that is non-yellowing in paint & that has

N. Dak. Breeding and Genetics of Flax . To (l) develop varieties 

 of flax with desirable agronomic qualities — high resistance to 

 wilt Fusarium lini ; resistance to races of rust; tolerance to 

 pasmo, Sphaerella linorum ; and quantity and quality of oil, 

 and seed yielding ability; and (2) determine if some relation- 

 ships exist between reaction to rust and other characters of 

 flax.

N. Dak. Preservation of Certain Physiologic Races of Flax Rust 

 Melamspora Lini . To (1) preserve and maintain in uredinial 

 stage races of flax rust having desired genes for virulence 

 on selected flax varieties; and (2) test material for flax 

 breeders who desire such assistance, or furnish them on re- 

 quest specific cultures for such testing.

Tex. Flax Improvement . To (l) develop or discover new varieties 



of flax better suited to Texas than now available, (2) search 

 for greater cold resistance among imported or domestic strains 

 & hybrid material, (3) cooperate in testing domestic & imported 

 strains for sources of disease resistance, cold resistance & 

 agronomic characteristics of value in the program, (4) test rate 

 & date of seeding, fertilizer needs of crop & cultural methods 

 for flax, (5) cooperate in control tests of nematodes & insects 

 which attack flax.
