Genetic Variance, Heritability And Correlation in Some Traits of Bread Wheat (triticum Aestivum L.) under Different Nitrogen Levels

Twelve genotypes of bread wheat, with four levels nitrogen (0, 75, 150, 225 kg N ha-1). were grown in split block design three replication growing season (2021), correlation, phenotypic and genotypic coefficient variation, heritability genetic advance estimated for (days 75% flowering, plant height, grain filling, yield, number spike/plant, spike length, weight, flag leaf area, biomes, protein harvest index. Highly significant positive correlation found between yield index protein.  While significantly 5% height. Broad sense was to be low the all studied traits followed by moderate values as percent
