BULLETIN 1284, U. S. DEPARTMENT OF AGRICULTURE 
There are four distinct varieties of milo: Standard Yellow, Dwarf 
Yellow, Standard White, and Dwarf White. Standard Yellow milo 
is the direct descendant of the milo first introduced into this country. 
It has been much improved through selection for shorter stalks and 
earlier maturity. Dwarf Yellow milo is a selection from the Stand- 
ard Yellow. It is 12 to 18 inches shorter than Standard Yellow and 
yields better when grown under dry conditions and at high altitudes. 
Standard White milo is similar to Standard Yellow except that 
the seeds are creamy white, usually shading into yellowish pink at 
the tip, while those of the Standard Yellow are yellowish pink 
throughout. It possesses no special advantage over Standard Yellow 
and does not compare favorably with Dwarf Yellow in yield. Dwarf 
White milo bears the same relation to Standard White milo that 
Dwarf Yellow milo does to Standard Yellow. It appeared under 
cultivation a few years ago on the plains of Texas and Oklahoma and 
is well adapted to the conditions there. The results of experiments 
on the milos are given in Table 7.
