Variation and inheritance of nitrogen content in seed of wheat genotypes (triticum aestivum l.)

In diallel crosses (without reciprocals) of four genetically divergent wheat cultivars (Jugoslavija, Osijecanka, Zitnica, and NS Rana 2) produced seed of hybrids which planted on experimental field. F-2 hybrids plants used for harvest and source of F-3 seeds which used for nitrogen content analysis. The mode of inheritance, gene effect, heritability in parent cultivars and F-3 hybrids were studied for nitrogen content in seed. On the base of obtained results, different mode of inheritance: dominance, intermediate and overdominance for content of N in seed was established. Among parent cultivars, the highest nitrogen contents had Novosadska Rana 2 (3.50%). The combination Osijecanka/NS Rana 2 in F-3 grain generation was the best for nitrogen content (3.70%)
