High temperature is an important global issue that impedes agricultural production, especially of soybean (Glycine max [L.] Merr.) crop. Numerous studies were undertaken to estimate the effect on seed germination under low temperatures. However, effects high-temperatures and early seedling establishment various cultivars need be explored further. Therefore, current study was performed in growth chambers evaluate genetic variations among different for varying Five temperatures, i.e., 15, 20, 25, 30, 35 ◦C, four (PI408105A, PI567731, PI567690, PI416937) used. The results showed revealed substantial percentage (GP), rate index (GRI), energy (GE), vigor (SVI), length temperatures mentioned above. indicated higher [35 °C] inhibited germination. Conversely, intermediate [20, 30 ◦C] depicted good Lower declined some extent, PI408105A, PI416937 observed as 63.33%, 56.67%, 50%, 40.11%, respectively. For all cultivars, mean maximum at 25 ◦C. continued increase until ◦C . cultivar PI408105A most promising high temperature, exhibiting GP by 86.67%, highest SVI 50.95%, GRI 50% In contrast, sensitive a only 20 seeds PI567690 can germinate well conditions, making them species use hot climatic zones. According findings, it concluded should planted mild crop stand production. Moreover, recommended such could grown warm conditions.
