“…no relationship between the stability and TKW was found among durum wheat genotypes Lama et al (2023). reported that some spring wheat genotypes with the highest stability had the lowest mean values for TKW.The results of TW, opposite to PC, showed increasing stability as the level of TW increased.…”

Wheat (Triticum aestivum L.) has become the most widely grown cereal crop in the Nordic-Baltic region, however, due to climate change its yields are under increasing risk. Here we present results of international effort harnessing available wheat germplasm in the region for identification of tools and genotypes for breeding wheat varieties with improved yield stability. We formed a panel comprising 300 spring wheat genotypes from Nordic-Baltic region and studied their phenotypic diversity across different environments to identify genotypes with high potential for adaptation to changing climate. Field experiments were carried out in 2021 and 2022 in Estonia, Latvia, Lithuania and Norway. The performance and stability of yield (GY), protein content (PC), thousand kernel weight (TKW), test weight (TW), length of growing period (GP), and nine other traits – were studied. Drought and excessive rainfall occurred in the Baltic countries in 2021–2022, whereas weather was more stable in Norway. High variability for most, and significant GxE effect for all the studied traits was identified. We found out genotypes combining yield and quality with stability using the AMMI model-based Weighted Average of Absolute Scores index (WAASB). Finally, we selected nineteen superior genotypes that combined high yield with high values of important quality traits. Thus, combining broad Nordic-Baltic wheat germplasm with extensive field phenotyping, we identified promising breeding material to develop climate ready spring wheat varieties for the region.

The results of the studies of photosynthetic activity of the seedlings of spring soft wheat three varieties and their adaptive responses to the combined effect of infection with the pathogen of common root rot of cereals Bipolaris sorokiniana Shoem. (B. sorokiniana) and chloride salinization on the parameters of chlorophyll fluorescence (ChlF) are presented. The seedlings were grown from pathogen-infected 3-day-old germinated seeds on sodium chloride solution (experiment) and on tap water (control) under specified climatic conditions. ChlF was recorded in 10, 12, 14, and 16-day-old seedlings using a Dual-PAM-100/F fluorimeter in a Slow Kinetics mode. The studies were carried out in 2022, 2023. The informativeness of the ChlF parameters Y(II), ETR, qP, Y(NPQ), qN and Y(NO) as biomarkers of photosynthetic activity and assessment of the resistance of the varieties to the combined effects of B. sorokiniana and chloride salinity was confirmed. The Fv /F0 and Fv /Fm parameters turned out to be less sensitive. The maximum significant intervarietal differences (from 1.8 to 4.3 times) were detected in six parameters of the ChlF. The smallest changes in ChlF parameters relative to the control were found in the more resistant variety Sibirskaya 21 compared to the less resistant varieties Novosibirskaya 41 and Novosibirskaya 29. Severe stress condition on the 16th day of cultivation of the Novosibirskaya 29 and Novosibirskaya 41 seedlings resulted in a synchronous increase in the parameter of unregulated non-photochemical quenching of ChlF Y(NO) by 45.8 and 59.9% and a decrease in the parameters of the regulated photochemical quenching Y(NPQ) and qN from 44.5 to 58.9%, respectively. This indicates a decrease in the efficiency of protective regulatory mechanisms during photosynthesis, which can serve as a diagnostic indicator in assessing the stress tolerance of varieties. It is concluded that it is possible to use ChlF parameters to assess photosynthetic activity, identify adaptive components and phenotyping of wheat varieties for resistance under the combined action of B. sorokiniana and chloride salinity.
