ALBA, OR WHITE, MELO. 



The variety Alba, or White, milo, is an exact counterpart of the 

 ordinary standard milo except in the color of the seed, which is white 

 instead of brown. The early history of this variety is not known. 

 It probably was introduced about 25 or 30 years ago. It was found 

 under cultivation in scattered locahties in western Texas, in 1909, 

 during an extensive reconnaissance made by the senior writer. It 

 has since been found sparingly in Oklahoma. Five different lots 

 were obtained in 1909 and included in the experiments in 1910. 



Fig. 6. — Diagram showing the seasonal (May to August) and annual precipitation, in inches, and the 

 acre yield of Dwarf milo (C. I. No. 332), in bushels, at the Amarillo Cereal Field Station in each of the 

 nine j^ears from 1908 to 1916, inclusive. 



The number was increased to nine in 1912, but during the last three 

 seasons only two lots have been grown. A total of 34 plats have 

 been grown in the seven years. The results obtained are given in 

 Tables X and XI. The Alba milo is so similar to milo in its adapta- 

 tions and reactions to environment that extended comment upon the 

 results seems unnecessary. 



The extremely prolonged ripening period in 1910 was due to the 

 very thin stand, which permitted free tillering, there being 70.8 per 

 cent of suckers in the total number of stalks. The many late- 

 appearing suckers matured slowly, thus 'prolonging the ripening an 

 extra 10 days. Only 60. 7 per cent of erect heads resulted. The 

 thin stand was due, in turn, to the immature condition of part of the 

 seed obtained in 1909, as the exploring trip was made before these 

 crops were ripe.
