Abstract:

Two field experiments were carried out at agriculture research stations of Agriculture Research Center (ARC). In 2014/2015 -2015/2016 seasons, the six parental genotypes were planted and the six parents were planted in a field experiment using the randomized complete block design with three replications. With the trials conducted, the correlation coefficients and path analysis were calculated between grain yield and yield components of wheat genotypes. The results revealed that that Gimaza-7, 10 and Misr1 cultivars were the best yielding among the studied cultivars and the Kafr Elhamam location was the top yielding than the other location (Itay-Elbarood). Positive and significant genotypic and phenotypic correlation was found between yield and No. of tillers per plant (NTP), No. of spikelets/ spike (NSS) and No. of spike /plant. Also, results indicated that, based on path analysis, it could be concluded that the most important sources of variation in grain yield. Genotypic and phenotypic coefficient of variation was high for No. of spike per plant and No. of tillers/plant, suggested that these yield components may be a good selection criteria to improve yield of wheat genotypes.
