abstract = "Usled ljudskih aktivnosti, zaslanjenost zemljišta postaje glavni izazov za globalnu
proizvodnju hrane. Pšenica je osnovna namirnica za veliki deo svetske populacije, a
stres zaslanjenosti predstavlja značajnu pretnju njenoj produktivnosti. Stoga je stvaranje
tolerantnih genotipova pšenice na salinitet od vitalnog značaja za obezbeđivanje
održive proizvodnje hrane, posebno u područjima pogođenim stresom saliniteta zemljišta.
Proučavanje genotipova pšenice u poljskim uslovima povećane zaslanjenosti je
ključno za efikasnu identifikaciju genotipova tolerantnih na salinitet. U skladu sa tim,
procenjena je tolerantnost 27 genotipova pšenice na salinitet na solonjecu u uslovima
saliniteta i černozemu kao kontroli tokom dve vegetacione sezone. Masa zrna po klasu,
koja je smanjena za 35% u uslovima saliniteta zemljišta, najbolji je fenotipski marker
uticaja zaslanjenosti na biljku. Takođe, povećana zaslanjenost zemljišta je smanjila
vrednosti broja zrna po klasu, mase klasa i prinosa zrna za 30%. Sprovedena je klaster
hitmap analiza, koja je omogućila hijerarhijsko grupisanje genotipova, odnosno osobina.
Masa hiljadu zrna, na koju je dominantan efekat imao faktor godina, svrstana
je u posebnu klaster grupu. U uslovima solonjeca, genotipovi Harmonija, Renesansa,
Orašanka, KG-58, Bankut 1205 i Oplenka su grupisani u okviru iste klaster grupe,
dok su u uslovima černozema usko povezani genotipovi Renesansa i Jugoslavija, ispoljavajući
najveće prosečne vrednosti ispitivanih osobina. Na osnovu AMMI analize,
genotip Harmonija pokazuje visoku stabilnost prinosa zrna na solonjecu i ocenjen je
kao genotip tolerantan na salinitet. Genotip Renesansa je ispoljio visoku stabilnost u
svim agroekološkim sredinama i ostvario najveći prinos zrna na černozemu., Soil salinity is becoming a major challenge for global food production due to
human activities. Wheat is a staple food for a large portion of the global population,
and salt stress is a significant threat to its productivity. Therefore, the development
of salt-tolerant and high-yielding wheat genotypes is vital for ensuring sustainable
food production, especially in areas affected by soil salinity stress. Consideration
of wheat genotypes under field salinity conditions is crucial for effectively identifying
salt-tolerant varieties. The salinity tolerance of 27 wheat genotypes was
assessed under field conditions by establishing an experiment on Solonetz, for
salinity conditions, and Chernozem, as the control, during two growing seasons.
The grain weight per spike, which decreased by 35% under soil salinity conditions,
is the best phenotypic marker of the influence of salinity on the plant. Also,
soil salinity reduced the values of the number of grains per spike, spike weight,
and grain yield by 30%. Cluster heatmap analysis was performed, which enabled
hierarchical clustering of genotypes and traits. The thousand grain weight, primarily
influenced by year, is classified into a separate cluster group. On Solonetz, the
genotypes Harmonija, Renesansa, Orašanka, KG-58, Bankut 1205, and Oplenka
were grouped together, and on Chernozem, Renesansa and Jugoslavija were closely
grouped, showing the highest average trait values. Based on the AMMI analysis,
the genotype Harmonija exhibits high grain yield stability on Solonetz and was
identified as the salt-tolerant genotype. The genotype Renesansa showed high
stability in all environments and achieved the highest grain yield on Chernozem.",
