Population improvement methods in sorghum

Abstract

The achievements of plant breeders, notably U.S.A. plant in the development of the sorghum crop have been very great. In reIat1vely few years the. crop has been transformed from tall phenotypes of rather unsuitable maturity length in the U.S.A. to well adapted types admirably suitable for fully mechanized agriculture, now occupying the third largest cereal average. if not all, of these changes have involved characters which are largely influenced by relatively few genes mainly heights, maturity lengths, some panicle and. owed and pest and disease resistances.
