Four wheat varieties were studied for the inheritance, gene effect and genotypic diversity of nitrogen harvest index (NHI). Significant differences occurred between parental varieties and progenies. Epistatic, non-allelic, effects were observed in NHI inheritance. The mode of NHI inheritance appeared to be dominance or overdominance. Dominance was more significant than additive gene effect. Heritability varied from 20-51% revealing complex gene systems responsible for NHI formation. The results obtained give hope of NHI improvement by selection process, which could be of a great economical and ecological importance. Mineral fertilization after variety request and translocation efficiency helps in securing environment and health care, leading to better preservation of the environment, and consequently healthfully improved food production.
