Plant breeding Breeding selfpollinated species | Britannica

Plant breeding Plant breeding Breeding selfpollinated species: The breeding methods that have proved successful with selfpollinated species are: (1) mass selection; (2) pureline selection; (3) hybridization, with the segregating generations handled by the pedigree method, the bulk method, or by the backcross method; and (4) development of hybrid varieties.

Plant breeding Hybridization | Britannica

Plant breeding Plant breeding Hybridization: During the 20th century planned hybridization between carefully selected parents has become dominant in the breeding of selfpollinated species. The object of hybridization is to combine desirable genes found in two or more different varieties and to produce purebreeding progeny superior in many respects to the parental types.

The Usage of Genomic Selection Strategy in Plant Breeding ...

Oct 10, 2017· Breeding population typically is just genotyped not phenotypes. Hence, Genomic selection depends on the degree of genetic similarity between training population and breeding population within the Linkage disequilibrium between marker and trait loci. Breeding values have not been a preferred index in plant breeding, however it is in animal breeding.

Markerassisted selection Wikipedia

Marker assisted selection or marker aided selection (MAS) is an indirect selection process where a trait of interest is selected based on a marker (morphological, biochemical or DNA/RNA variation) linked to a trait of interest ( productivity, disease resistance, abiotic stress tolerance, and quality), rather than on the trait itself. This process has been extensively researched and ...
