Grass Strains 

 Differences Between "Strains" may be of Real Practical Importance. 



Above : The short-growing orchard grass strain on the right is a late leafy hay type which can 

 be grown satisfactorily with alfalfa. It is much more desirable than either of the two coarse- 

 stemmed early-maturing strains on the left. 



Below : The Svalof early meadow fescue on the right is apparently immune to leaf rust whereas 

 the "commercial" meadow fescue on the left is very susceptible.
