evidently transmitted. Hence, the strains of alfalfa can be made more 
uniform through seed selection- This is illustrated in Plates Nos. 13 
and 14, which are sections from the same nursery. Plate No. 13 is 
a row sown with seed from selections for three generations. The 
plants are all desirable and relatively uniform. Plate No. 14 is an¬ 
other row seeded with commercial seed. It shows four markedly ir¬ 
regular types of plants, none of which are especially desirable. Thus 
the results of systematic seed selection have been very encouraging. 
The conclusion is: That a hardy, desirable hay producing alfalfa, 
with good seed yielding tendencies, is within easy reach by means of 
systematic seed breeding.
