    U cilju procene tolerantnosti pÅ”enice na stres saliniteta, sproveden je dvogodiÅ”nji ogled sa 27 genotipova pÅ”enice, gajenih na dva lokaliteta: Kumane (solonjec, povećana zaslanjenost) i Rimski Å ančevi (černozem, kontrola). Stres zaslanjenosti je uticao na smanjenje prinosa zrna po klasu za oko 30%, Å”to ovu osobinu čini dobrim fenotipskim markerom uticaja stresa zaslanjenosti na razvoj pÅ”enice. Selekcija zasnovana na vrednostima indikatora SP, ITS i IP favorizuje odabir genotipova Bankut 1205, OraÅ”anka, KG-58, Jugoslavija, Renesansa i Harmonija. Iz grupe genotipova sa visokim vrednostima SP, ITS i IP (klaster A), genotip Harmonija ima nisku vrednost parametra IOS (0,52) i visoke vrednosti ISP (0,84), IP (1,66) i prinosa zrna po klasu na solonjecu (1,50 g), Å”to ga čini veoma tolerantnim genotipom na salinitet. Parametri IOS i ISP identifikuju genotipove koji se, bez obzira na nizak prinos, odlikuju malom osetljivoŔću na stres (Å umadija, Rujna i Premija), zbog čega mogu biti koristan genetički resurs u oplemenjivačkim programima.In order to assess the tolerance of wheat to salinity stress, a two-year trial was conducted with 27 wheat genotypes, grown on two soil types: Solonetz (salinity stress) and Chernozem (control). Salinity stress reduced grain yield per ear by about 30%, which makes this trait a good phenotypic marker of salinity stress. Selection based on SP, ITS and IP indicators favors the selection of genotypes Bankut 1205, OraÅ”anka, KG- 58, Jugoslavija, Renesansa, and Harmonija. From the group of genotypes with high values of SP, ITS and IP, the genotype Harmonija has a low value of the parameter IOS (0.52) and a high value of ISP (0.84), IP (1.66), and grain yield per ear on the Solonetz (1.50 g), which makes it salinity-tolerant genotype. The parameters IOS and ISP identify genotypes that, regardless of low yield, are characterized by low sensitivity to stress (Å umadija, Rujna, and Premija), because these genotypes could be a useful genetic resource in breeding program
