Genetic analysis of nitrogen accumulation in four wheat cultivars and their hibrids

Improvement of N accumulation in the plant leading to an increasing grain N content and yield is one of the major tasks of wheat breeding. Since N absorption from soils and translocation from roots and leaves to grains are primarily under genetic control. Breeders need make concept of creation new genotypes with high capacity of accumulation as well with high capacity of N uptake, utilization and translocation. Also, development of new genotypes with high capacity of N utilization will contribute to decreasing rate of application of nitrogen fertilizers what is very important for environmental protection. Developed genotypes by crossing Zitnica × NS Rana 2 cultivars is promising for sustainable agriculture growing, because of its low requirements for fertilizer application.
