Abstract:
Rice (Oryza sativa) is a nutritive staple foods and one of the most important cereal crops, especially for people in Asia, but the consumption outside Asia has increased, recently. It provides the bulk of daily calories for many companion animals and humans. It has good digestibility, biological value and good quality protein due to the presence of higher amount of lysine. Rice has greater variability of the glycemic index depending on type, cooking method, etc. Rice is also one of food which is considered to be a potential food vehicle for the fortification of micronutrients because of its regularly consumption. Zn and Fe deficiency is a global nutritional problem and intensity of the issue is even severe in developing countries. Cereal grains are key to fulfill a person’s daily energy requirements, but they have very low grain Zn-Fe concentrations, especially when grown in Zn-Fe deficient soils. Seeds of 52 lines of rice were used in this investigation indicated that line 383441 contains high amount of N, P, K, Na, Fe, Zn and nitrogen protein. Therefore, this line may be considered for utilization by breeders for development of high N, P, K, Na, Fe, Zn and nitrogen protein containing lines/varieties. With regards to Zn and Fe status in grains, line 282418 contained the maximum amounts of these elements. Therefore, this line may be utilized by breeder to develop high Zn and Fe containing lines/varieties.
