Breeding Cross-Pollinated Crops
While methods for improving self-pollinated species tend to focus on improving individual plants, improving cross-pollinated species, on the other hand, tends to focus on improving a population of plants. A population is a large group of interbreeding individuals. The principles of population genetics are applied to effect changes in the genetic structure of a population. The change is such that only desirable genotypes predominate in the population. In this process of changing gene frequencies, new genotypes will arise. This genetic variability must be maintained so that they can be utilized for further improvements in the future.
