Conventional breeding, is still dependent to a considerable extent on subjective evaluation and empirical selection. The process can be difficult, slow, influenced by the environment, and costly for the economy, as farmers suffer crop losses. Molecular marker assisted breeding (MAS) offers great challenges, opportunities and prospects for conventional scientific breeding, needs less subjectiveness and more science, i.e. practical and accurate evaluation and effective and efficient selection. MAS allows selection for all kinds of traits to be carried out at seedling stage and thus reduce the time required before the phenotype of an individual plant is known.
