Races of Maize in Bolivia

This is the sixth inventory of maize races of the Americas, a part of the systematic cooperative program of corn improvement underway for a decade, which provides viable seed for studies leading to a better understanding of the genetic problems of maize. Described with precise techniques are 32 races, tentatively classified as such, following the planting and study, in Colombia, of a collection of 844 Bolivian varieties, secured at altitudes varying from 500—12,500 ft. Included are résumés of the geography of Bolivia and of its indigenous peoples as related to maize problems. An excellent bibliography accompanies this important publication.
