WebbThe most important methods of breeding cross-pollinated species are (1) mass selection; (2) development of hybrid varieties; and (3) development of synthetic varieties. Since cross-pollinated species are naturally hybrid (heterozygous) for many traits and lose vigour as they become purebred (homozygous), a goal of each of these breeding methods is to … WebbRecurrent Selection: The idea of recurrent selection was first suggested by Hayes and Garber in 1919 and independently by East and Jones in 1920.
