The aim of this work was to investigate the possibility of using winter wheat genetic resources tolerant or sensitive to low pH and Al3+ ions. At two pH levels of nutrient solution (pH 4 plus Al3+ and pH 7 without Al3+), after hydroponic way of cultivation (12 days) juvenile plants of winter wheat (phase of 2nd leaf) have been tested for tolerance to low pH and Al3+ ions. There were evaluated varieties and hybrid populations of F2 generation of tolerant and sensitive varieties Albota and Scout-66 with varieties (Torysa, Barbara, Livia, Ilona, Py-11). As a check varieties were cultivated foreign tolerant varieties Albota and Atlas-66 and as a sensitive variety Scout-66. There were evaluated following traits: length and weight of roots, length and weight of above ground parts. The results have shown that the check varieties are more tolerant respectively more sensitive as our registered varieties. More tolerant and more sensitive are also hybrid of these variety combinations what confirm differences mainly between length and roots weight of plants cultivated in the acid medium with Al3+. From these results follows, that tolerant variety Albota could be used in breeding process as a donor for transmission of tolerance property
