Comparison of the degree of inhibition of growth processes of pea (Pisum sativum) accessions which were obtained by the method of laboratory heat test (heat resistance) and by the method of germination on PEG-6000 solution (simulation of soil drought). Germination of pea genotypes on PEG-6000 solution was carried out at a solution concentration of 8.6%, control - on distilled water. During the thermal test, a water-filled thermostat was used, the temperature regime was 50°C and the exposure time was 40 minutes. The seeds were germinated at 21°C for 6 days. Roots and shoots were then measured. For experiment 8 samples of peas were used - Camelot, Maskara, Efektnyy, Malakhit, SL 12-20, Kharkivskyy yantarnyy, SL 11-25 and Damyr 2. According to the results of germination on PEG-6000, the lowest level of depression of the indicators "root length" and "shoot length" was found in the Camelot (+47.1%/18.7%), Mascara (+32.0%/44.4%), Kharkivskyy yantarnyy (+7.73%/+34.1%) and SL11-25 (+96.3%/11.9%) cultivars. These accessions showed root growth on the PEG-6000 solution compared to the control. Damyr 2 (50.2%/53.7%), Efektnyy (19.9%/56.2%), Malakhit (+4.4%/30.6%) and SL 12-20 (+4.7/64.8%) did not show high resistance. The level of depression indicators obtained during the thermal test was higher for Maskara variety (68.8%/75.8%) and SL 11-25 (69.4%/53.0%). The Camelot (38.2%/+31.9%) and Kharkivskyy yantarnyy (65.7%/38.9%) varieties showed high resistance to the action of the thermal test. And, on the contrary, the varieties that did not have a high level of resistance to the action of PEG-6000 turned out to be resistant to elevated temperatures - Damyr 2 (29.9%/+7.4%) and Effectnyy (47.4%/31.2%). The genotypes Malakhit (57.6%/63.5%) and SL12-20 (76.0%/84.8%) did not show high resistance to high temperatures. Variety Camelot stands out, showing a high level of resistance in both studies, both to the effect of osmotic fluid and to the conditions of the thermal test. The calculated Spearman coefficient (rs= - 0.48, tfact= 1.34 with ttab= 2.44) for the rows of the matrices was insignificant. This means that the results obtained reflect completely different mechanisms of response to these stress factors.
