Abstract

Two steps are essential to achieve genetic advances in plant breeding programs: (a) to obtain populations which possess genetic variability and (b) to practice selection to isolate the desired genotypes. The basic origin of genetic variability is mutation, either genic or chromosomal. Originally, plant breeding of self-pollinating crop species consisted of selecting among natural variants. Intense selection soon exhausted progress from natural variability and plant breeders were forced to hybridize between genotypes to develop new genetic variability.
