Eugenia Larjow,Christian Reuschenbachinciples upon which the procedure is based may remain unchanged. In this chapter models of breeding systems applicable to cross-pollinated species are presented. The modifications necessary to adapt the procedures to the breeding of corn, sorghum, millet, cotton, sugarbeets, forage crops are discussed further in Chapters 18–22, respectively.
