Effect of growing seasons on some quality properties of winter wheat genotypes

Abstract

In this research, 16 genotypes of winter wheat (Triticum aestivum L.) were analyzed where 15 genotypes represent perspective lines created in Center for Small Grains in Kragujevac and one standard cultivar. Field experiment was conducted in three growing seasons (2012/13, 2013/14 and 2014/15) on the experimental field of Center for Small Grains in Kragujevac (Serbia). Some grain quality parameters (hectoliter weight and 1000 grain weight) were analyzed in this paper. In average for three years, values of hectoliter weight varied from 76.65 kg hl-1 (KG-60-3/3) to 80.05 kg hl-1 (KG-1/6). The analyses of variance showed highly significant differences in hectoliter weight between genotypes (F=4.554**) and investigated years (F=150.082 **), but interaction genotype x year was significant (F=1.629*). The highest values of 1000 grains weight expressed line KG- 52/23 (46.75 g) and the lowest line KG-28/6 (39.90 g). Compared to the standard cultivar Pobeda, 10 genotypes had higher values of 1000 grains weight. There were highly significant differences in the weight of 1000 grains among genotypes (F=25.011**), investigated years (F=117.267**), as well as their interaction (F=8.684**).
