The cultivars are well adapted to the temperate climate conditions with occasionally low temperatures in the winter season. The mean winter hardiness of the cultivars was evaluated by 7.8, 7.3, 8.2 and 7.3 scores, respectively and surpassed the well adapted and previously widely grown check cultivar 'Zentos' (6.8 scores). The cultivars exhibit good resistance to sprouting in ears, which is important in regions with high humidity during the harvesting period. They can be grown under sustainable and high input growing conditions. The mean grain yield of cultivars 'Kena DS', 'Sedula DS', 'Gaja DS' and 'Herkus DS' in high input fields during 2011-2016 was 8.7, 8.6, 9.9 and 9.1 t ha -1 , respectively. The grain yield of the high yielding check cultivar 'Skagen' was 8.6 t ha -1 . The mean protein content of cultivars 'Kena DS', 'Sedula DS', 'Gaja DS' and 'Herkus DS' was 14.3, 13.3, 13.6 and 13.3 %, sedimentation value -61.2, 49.2, 34.5 and 49.3 ml, respectively. The dough stability of the new cultivars determined by a Brabender's pharinograph was 12.7, 6.0, 7.3 and 6.9 min, volume of bread baked from 300 g of flour was 1600, 1650, 1700 and 1520 cm 3 , respectively. The total baking value index of the cultivars 'Kena DS', 'Sedula DS', 'Gaja DS and 'Herkus DS' was evaluated by 700, 725, 750 and 660 scores respectively, where the excellent bread-making cultivar 'Ada' attained 670 scores. The new cultivars exhibit good resistance to powdery mildew (Blumeria graminis DC), acceptable resistance to tan spot (Pyrenophora tritici-repentis Died.), take-all (Gauemanomyces graminis Sacc.), Septoria glume blotch (Phaeosphaeria nodorum E. Müll) and Septoria leaf blotch (Zymoseptoria tritici (Desm.) The cultivars are included in the Lithuanian National List of Plant Varieties and EC Common Catalogue of Cultivars of Agricultural Plant Species.

Mineral Composition and Baking Value of the Winter Wheat Grain under Varied Environmental and Agronomic Conditions

“…e baking value of grain and flour describes many traits, most importantly those which characterize its enzymatic complex (falling number) and protein complex (the content of total protein and wet gluten and sedimentation value). A comprehensive evaluation, however, is only provided by a baking test, including the bread volume evaluation [20,21]. e content of macronutrients and micronutrients as well as other grain quality traits are genetically determined.…”

Transcriptome changes triggered by a short-term low temperature stress in winter wheat

“…The experiment was carried out at the Institute of Agriculture, Lithuanian Research Centre for Agriculture and Forestry in 2019. Lithuanian winter wheat (Triticum aestivum L.) cultivar 'Gaja DS', characterized as winter-hardy and well-adapted to temperate climate conditions (Ruzgas, Koppel, 2017), was used in this study. Pre-germinated seeds were planted in peat moss potting substrate.…”

Effects of different sowing time to phenology and yield of winter wheat

“…For this experiment winter wheat cultivar 'Skagen' was selected. It has notable winter hardiness and relatively high productivity compared to other cultivars which made it popular among farmers not only in Lithuania but across Europe (Ruzgas et al 2017, Feledyn-Szewczyk et al 2018.…”
