Marker-assisted Breeding Rationale

With a world population projected to be over 9 billion in 2050, there is an urgent need for enhancing agricultural production to ensure food security and increase income of the rural poor. Due to a variety of abiotic and biotic stresses such as drought, insect pests, and disease problems as well as weeds and poor plant nutritional conditions, most crops do not reach their full potential in the farmers’ fields. Plant breeders can play a significant role in developing newer varieties that can combat the various biotic and abiotic limitations. To the resource poor farmers especially in the developing world who depend on rain-fed cultivation and cannot afford chemical pesticides or fertilizers to increase the yield potential of their crops, access to newer and better yielding varieties may remain the only available option.

However, in order to develop newer and higher yielding varieties faster, it is important that a plant breeder has the skill set and access to existing and new biotechnological tools such as marker assisted breeding approaches, which are currently being used extensively by breeders in the developed world to increase the efficiency of breeding programs. Often in the developing world, these new tools of biotechnology fail to reach plant breeders and so fewer technological advances are applied in the farmers’ fields. We believe that this gap can be bridged through awareness and education.

Program Description

Marker assisted breeding (MAB) is an approach where genetic markers (usually DNA based markers) are used to monitor the presence of desirable and undesirable genes in breeding plants. Therefore, based on the information provided by the genetic markers, breeders will only need to field test those breeding plants that are most likely to have desirable traits, a great cost saving especially when breeding perennial crops.

The use and integration of genetic markers need well-trained human resources with practical experiences in various aspects of molecular plant
breeding. This requires training and skill development in conventional plant breeding, genetics of the inheritance of qualitative and quantitative traits, developing DNA markers for traits of interest, analyzing complex data sets using computer software programs as well as performing marker assisted selection in the field based on the results of genetic tests performed; often involving a team of experts in the various areas to assist breeders in their decision-making process. However, for a plant breeder to reap the benefits of the marker technology, he/she should understand the various steps involved in MAB. For this, short-term awareness and educational programs can be effectively utilized. Therefore, the Marker-assisted breeding training program is designed to not only cover the marker technologies available to a plant breeder for crop improvement but also to provide hands-on experience in the use of computer software programs for developing markers for traits of interest. Through a participatory approach, the program also fosters linkages and opportunities for networking among participants often leading to collaborative projects.
