AB  - Environmental stresses such as drought, cold and heat in Pannonia Basin significantly endanger the cell activity, plant growth and yields in wheat, which is one of the most strategic cereal grain crops in the world. As science and technology advance, new tools are developed while old ones are refined for use by breeders. Higher agronomical efficiency is possible by combining new and old tools to bridge the abiotic stress issues. Five cultivars of winter wheat (Simonida, Petrija, Ljubica, Zvezdana and NS Mila), were used in the study carried out at our experimental field (Novi Sad as a center of Pannonia Basin) across three consecutive growing seasons to assess genetic interaction and the level of tolerance and adaptability of different cultivars to abiotic stresses like drought conditions, cold and heat. Four quantitative yield components and grain yield were analized to assess expression of adapted genotypes in the region. Among the cultivars, Simonida, which has been in use for the longest period, exhibited the most consistent yield response. Additionally, it demonstrated some degree of partial tolerance to abiotic stress conditions, possibly due to the integration of stress memory into its genetic code, supported by statistical analysis findings.
AB  - Stres izazvan ekološkim činiocima kao što su suša, niske i visoke temperature u Panonskom basenu značajno ugrožavaju ćelijsku aktivnost, rast biljaka i prinos pšenice, koja predstavlja jednu od najvažnijih strateških žitarica u svetu. Kako nauka i tehnologija napreduju, novi alati se razvijaju, dok se stari usavršavaju i stoje na raspolaganju oplemenjivačima. Ipak, postizanje veće agronomske efikasnosti je moguće ako se napravi zajednička veza između njih, kako bi se premostili problemi nastali pod uticajem abiotičkog stresa. U ovom istraživanju, koje je sprovedeno na našem oglednom polju (Novi Sad kao centar Panonskog basena), je korišćeno pet sorti ozime pšenice (Simonida, Petrija, Ljubica, Zvezdana i NS Mila), u tri uzastopne vegetacione sezone, kako bi se procenila genetička interakcija i nivo tolerancije i prilagodljivosti različitih sorti pšenice na abiotičke stresove kao što su suša, niske i visoke temperature. Prinos i četiri kvantitativne komponente prinosa su analizirane kako bi se procenila ekspresija prilagođenih genotipova u ovom regionu. Rezultati statističke obrade podataka su potvrdili da sorta koja je najduže u upotrebi, Simonida, ima najkonzistentniju reakciju na prinos, i da poseduje određeni stepen delimične tolerancije na uslove abiotičkog stresa, koju je ugradila preko stres memorije u svoj genetički kod.

AB  - Climate change projections for the 21st century pose great threats to semi-arid regions, impacting seed production and the quality of sunflowers. Crop yields are negatively affected by climate variability, especially in the event of droughts during the crucial growth stages. Understanding the relationships between agrometeorological, genetic, and agronomic factors is crucial for maintaining crop sustainability. Optimal sowing dates are an essential condition for maximizing crop genetic potential, but challenges come from annual weather variations. This study analyzes how sunflower genotypes respond to different sowing dates under climate change and focuses on the conditions for obtaining maximum seed yields and favorable agronomic traits. From 2020 to 2022, the experiment featured six genotypes sown across four different dates at two-week intervals, simulating seed sunflower production. The results obtained by ANOVA indicated that the seed yield and oil yield were significantly affected by the sowing date, the genotype, and their interaction, with coefficients of variation ranging from 7.6% for oil yield to 41.1% for seed yield. Besides seed yield and oil yield, LDA biplot and Discriminant Functions confirmed that seed germination energy also played a significant role in separating genotypes into clusters. A Visual Mixed Model showed that shifting the optimal sowing date (mid-April) to early May allows a reduction in the number of days the plants spend in critical growth stages, thereby escaping stressful conditions during pollination and seed filling. The findings resulted, on average, in increased yields and improved seed quality, which are the primary goals of seed production, but not in increased 1000-seed weight. Notably, high temperatures during the critical sunflower growth stages negatively affected the measured parameters of seed production. The increased precipitation during seed filling boosted the  1000-seed mass and seed yield. Extended flowering reduced the growth rate and seed germination, but longer seed filling increased the 1000-seed mass and seed yield. Our future breeding goals will be to create genotypes with a shorter flowering period and an extended seed-filling period to better respond to climate change.
