Abstract. The purpose of the study was to identify the genotypes of spring grain crops resistant to the action of aluminium. The work was performed on 5-day-old seedlings of roll cultures (30 varieties and breeding lines of each of the following cultures: spring oat, spring triticale, spring wheat, spring barley). Distilled water (pH 6.0) was a control; the experimental options were aqueous solution of Al2(SO4)3 at concentrations of 0.5 mM, 1.0 mM, 1.5 mM, 2.0 mM, and 2.5 mM (pH 4.3). We determined the following indicators: root length index (RLI, %), root index (RI, units), stability coefficient (SC, %). Cluster analysis (Ward’s method) was used to rank the samples. In the control option, the greatest length of seedlings and roots as well as the mass of dry shoots and roots were noted in triticale; it surpassed other cultures in terms of these indicators by 14.1–55.0%. The cultures most resistant to the action of aluminium in the concentration range of 0–2.5 mM Al were spring oat and spring triticale (RLI=22–65%). They were followed by wheat (RLI=14–51%); barley turned out to be the least resistant (RLI=10–48%). We identified the samples of grain crops, which formed separate clusters on dendrograms with the maximum resistance to the action of aluminium ions in the experiment. These were oat varieties Tigrovy, Premier, Peredovik, Kardinal, Marshal, 547-12, 318-14, 510-15, 437-05, 474-17; wheat varieties Dalira, Anfeya, Elizaveta, Zaryanka, Lira-98, Priamurskaya, Khabarovchanka, 42/1-14, 65/2-11, 26/2-14; barley varieties Ya-211, Ya-115, Ya-96, Musson, Yerofey, Rus’, and Khabarovsky; triticale varieties 205-20, 185-20, 128-20, 226-20, 188-20, 117-20, 104-20, 184-20, 206-20, 182-20, 109-20, 106-20, and 103-20.
