Genetic Analysis of Grain Yield Attributes and Protein Content in Bread Wheat Under Different Nitrogen Fertilization Levels.

Abstract: Six diverse wheat cultivars (Triticum aestivum L.) were used in a partial-diallel crosses to produce 15 F1, hybrids. Genetical analysis and heritability, was estimated for days to heading, days to maturity, grain filling period, plant height, spike length, number of spikes /plant, 1000-grain weight, number of kernels per spike, grain yield/ plant and grain protein content. Mather and Jinks (1971) and Hayman(1954 a and b) methods were used to estimate the genetic parameters for studied characters. Significant m… Show more

“…High heritability estimates, coupling with other parameters can be used in predicting genetic gain follows by selection for these characters. Selection of different wheat genotypes under environmental stress conditions is one of the main missions of crop breeders for exploiting the genetic variations to improve the stress tolerant wheat cultivars (Gebrel et al, 2014;Khan and Mohammad, 2016;.…”
