The role of genetic breeding in food security: A review

Abstract

Genetic engineering or breeding entails deliberate modifications of the characteristics of an organism by manipulating its genetic makeup. This technique has been used to develop crops which are high yielding, resistance to pest and disease, high nutritional value, high oil content etc. Genetic engineering technique offers mankind the ability to develop crops with desirable characteristics within a very short period compared to conventional breeding methods. The use of this breeding method has resulted in producing some varieties of crops which requires farmers to invest low during production for higher income after harvest. The aim of this article is to summarise the known role genetically modified crops has played to reduce hunger and the provision of food with the required nutritional value in helping the world to become a food secured one.
