The genetic diversity among 56 bread wheat (Triticum aestivum L.) genotypes was evaluated by 18 agronomical traits in the experimental field at Maragheh, Iran. Significant differences among bread wheat genotypes in all of the measured traits i.e. stem diameter, plant height, leaf number, leaf length, leaf width, tiller number, internode length, peduncle length, spike length, floret number, spikelet number, grain number, length of awn, grain diameter, grain length, the number of days to flowering, thousand seed weight and grain yield. The coefficient of variation (CV) was high for grain yield (25.61%), number of tillers per plant (22.06%) and number of grains per spike (21.45). The other remaining traits recorded moderate to low CV estimates from 14.30% in grain number per spike to 4.81% in days to flowering. The largest thousand seed weight was 45.93 g, the lowest thousand seed weight was 26.16 g and the mean thousand seed weight was 37.85 g. The mean performance of grain yield was 5031.2 kg ha-1, the minimum grain yield was 2835.0 kg ha-1 and the maximum grain yield was 7125.3 kg ha-1. Ward’s minimum variance cluster analysis based on squared Euclidian distance on the raw data of 18 agronomic traits clearly separated five clusters. In general, cluster analysis of the 56 genotypes based on the selected agronomic traits was consistent with known information. Our plant materials could be important germplasm resources for enriching the genetic background of commercial cultivars. Such genetic differences of bread wheat traits studied in this investigation can be applied as a new source of variation in other breeding programs and crossing nurseries in breeding program

This publication presents the results of a field assessment of 225 winter bread wheat accessions from the VIR collection for their winter hardiness in the environments of the Northwestern (Town of Pushkin, 2007/2008, 2008/2009 and 2013/2014) and Central Black Earth (Yekaterinino Settlem., 2007/2008 and 2008/2009) Regions of the Russian Federation. The tested accessions included landraces and old improved varieties, earlier identified as sources of winter hardiness, as well as modern improved cultivars and lines, added to the VIR collection from 1990 through 2006. For reference purposes, along with the wintering data, information on biological and agronomic traits is given for the tested accessions. The presented data will be of interest to plant breeders and other experts working with winter bread wheat.
