Evaluation of salinity stress tolerance in various wheat genotypes
U cilju procene tolerantnosti pŔenice na stres saliniteta, sproveden je
dvogodiŔnji ogled sa 27 genotipova pŔenice, gajenih na dva lokaliteta:
Kumane (solonjec, poveÄana zaslanjenost) i Rimski Å anÄevi (Äernozem,
kontrola). Stres zaslanjenosti je uticao na smanjenje prinosa zrna po klasu
za oko 30%, Å”to ovu osobinu Äini dobrim fenotipskim markerom uticaja
stresa zaslanjenosti na razvoj pŔenice. Selekcija zasnovana na
vrednostima indikatora SP, ITS i IP favorizuje odabir genotipova Bankut
1205, OraŔanka, 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), Ŕto ga
Äini veoma tolerantnim genotipom na salinitet. Parametri IOS i ISP
identifikuju genotipove koji se, bez obzira na nizak prinos, odlikuju
malom osetljivoÅ”Äu na stres (Å umadija, Rujna i Premija), zbog Äega mogu
biti koristan genetiÄki resurs u oplemenjivaÄkim 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, OraŔanka, 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
