Stability of yield and miller's quality of winter wheat selected varieties' grain

Within the project of small-plot field trials we cultivated 10 varieties of winter wheat in 5 different trial stations of the Central Institute for Supervising and Testing in Agriculture in years 2001–2002. The yields achieved were assessed and the miller’s quality of the grain was defined. Wheat va...

Sumari:Within the project of small-plot field trials we cultivated 10 varieties of winter wheat in 5 different trial stations of the Central Institute for Supervising and Testing in Agriculture in years 2001–2002. The yields achieved were assessed and the miller’s quality of the grain was defined. Wheat variety Contra reached the highest yields (10.226 t.ha–1) and Niagara wheat variety reached the lowest yields (8.516 t. ha–1) where the yields were conclusively lower (LSD, 95%) compared with the group C varieties. Apache and Ebi varieties achieved the most stable yields; the least plastic variety was Banquet. We marked high variability of volume capacity (682–840 g.1–1). The highest average volume capacity was proved by Niagara variety (802 g.1–1) while the lowest was provided by Windsor (736.9 g.1–1). The elite group wheat varieties (E) and the quality varieties (Niagara, Samanta) proved conclusively higher volume capacity than the group C varieties. The highest TGW, in comparison with the rest of varieties, was achieved by Niagara variety and the lowest TGW proved by Contra. The high proportion of grains on 2,5 mm sieve corresponded with TGW. In average, the highest proportion of grains on 2,5 mm sieve was achieved by Niagara variety (95.21%), the lowest by Contra. Higher TGW value achieved in 2001, in comparison with 2002, positively influenced the yield of flour. The highest yield were reached by the A class flour in 2001 and the elite wheat (E) in the following year. The highest content of ashes in flour T550 was found at Windsor variety (0.61%) contrary to the most positively evaluated Samanta (0.55%).
