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