Plant breeders have been successful In exploltlng available variability in crop specles by dlrect selection among landraces and by the use of conventional methods of pedigree and backcross breeding in the development of superlor genotypes. Effective use of population breedlng methods began some 30 years ago wlth the increased knowledge of quantltatlve genetlc theory and reallzatlon of the fact that conventional breeding methods produce populations w~th a relatively small gene pool, favor the accumulat~on linkage blocks due to rapld fixation of genotyes, and limit recombinatlon optlons because of P the lack of intermatlng. Population brdedlng techniques involving recurrent selection have greater potential for mob~lizing genetic varlatlon and provide increased opportunities for recomblnatlon and selectlon.
