            1

Aim. Detailed examination of different studies showed that the thickness of the straw second internode of soft winter wheat is not sufficient investigated. Methods. The article presents the results of an experiment for the study of the formation and the variability of the trait thickness of the straw second internode (TS-2M) in different soft winter wheat (Triticum aestivum L.) varieties and breeding lines. There are forty one wheat varieties of different origin presented in this study. Results. It was established that the trait TS-2M significantly correlated with the main yield traits. Therefore, the selection of productive genotypes in the selection process based on TS-2M is effective. Conclusions. The statistical analysis of winter wheat varieties based on the trait TS-2M showed that the level of formation and variability of this trait is genetically determined. Keywords: winter wheat, the second internode (ТS-2М), genetic coefficient of variation (CV%).

Yield Test

Valor is a new, medium-hard, red winter feed wheat (Triticum aestivum L.) that is adapted to the Maritime Provinces of Canada. Valor was licensed in July 1981. Compared with Lennox, the principal winter wheat of the area, Valor has slightly higher yield, test weight and 1000-kernel weight, as well as greater winter survival and more resistance to powdery mildew. Valor has slightly weaker straw and lower grain protein.

Wheat Varieties

For food security, it is essential to identify stable, high-yielding wheat varieties with lower disease severity. This is particularly important due to climate change, which results in pressure due to the increasing occurrence of Fusarium head blight (FHB). The objective of this study was to evaluate the stability of winter wheat (Triticum aestivum L.) grain yield under different environmental conditions. Twenty-five winter wheat varieties were evaluated under two treatments (naturally-disease infected (T1) and FHB artificial stress (T2)) during two growing seasons (2018–2019 to 2019–2020) in Osijek and in 2019–2020 in Tovarnik. The interaction between varieties and different environments for grain yield was described using the additive main-effects and multiplicative interaction (AMMI) effects model. The Kraljica and Fifi varieties were located near the origin of the biplot, thus indicating non-sensitivity to different environmental conditions. Principal component analysis (PCA) was used to understand the trait and environmental relationships. PC1 alone contributed 42.5% of the total variation, which was mainly due to grain yield, 1000 kernel weight and test weight in that respective order. PC2 contributed 21.1% of the total variation mainly through the total sedimentation value, test weight, wet gluten and protein content ratio (VG/P) and wet gluten content, in descending order.
