Utilization of Potato Germolasm for Breeding

Abstract

The theoretical rationale of a potato breeding scheme is presented. This scheme involves: 1) utilization of germoplasm in the development of tetraploid and diploid populations with a wide base of inheritable variability; 2) breeding of these populations through cycles of sexual reproduction and recurrent selection; 3) synthesis of hybrids between selected individuals (clones) from different populations and evaluation of these hybrids on the basis of their agronomic aptitude.
