U cilju procene tolerantnosti pšenice na stres saliniteta, sproveden je
dvogodišnji ogled sa 27 genotipova pšenice, gajenih na dva lokaliteta:
Kumane (solonjec, povećana zaslanjenost) i Rimski Šančevi (černozem,
kontrola). Stres zaslanjenosti je uticao na smanjenje prinosa zrna po klasu
za oko 30%, što ovu osobinu čini dobrim fenotipskim markerom uticaja
stresa zaslanjenosti na razvoj pšenice. Selekcija zasnovana na
vrednostima indikatora SP, ITS i IP favorizuje odabir genotipova Bankut
1205, Orašanka, 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), što ga
čini veoma tolerantnim genotipom na salinitet. Parametri IOS i ISP
identifikuju genotipove koji se, bez obzira na nizak prinos, odlikuju
malom osetljivošću na stres (Šumadija, 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, Orašanka, 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 (Šumadija, Rujna, and Premija), because these
genotypes could be a useful genetic resource in breeding program
