Plant breeding is a method of altering the genetic pattern of plants to increase their value and utility for human welfare. It is a purposeful manipulation of plants to create desired plant types that are better suited for cultivation, give better yield and are disease resistant.
Molecular breeding is the application of molecular biology tools, often in plant breeding and animal breeding. The areas of molecular breeding include: QTL mapping or gene discovery. Marker assisted selection and genomic selection. Genetic engineering.
