ABSTRACT
The world’s population is projected to increase to 9 billion by 2050 (Roberts 2011), while the availability of arable land will decrease as environmental degradation and destruction grow worse. Meeting the food demand of this growing population will be a major challenge, and a food shortage is projected. Therefore, it is imperative that we produce crops with improved quality and quantity using conventional selection and breeding, or genetic engineering, in order to meet the growing food demand through sustainable agricultural systems (Ashraf and Akram 2009).
