Abstract
We discuss the properties of the Wolf-Rayet (WR) stellar population in the most metal-deficient blue compact dwarf (BCD) galaxies. It is shown that massive stars with stellar wind are present in several BCDs with oxygen abundance 12 + log O/H < 7.6. In particular, a variety of late nitrogen (WN7 – WN11) and early carbon (WC4) Wolf-Rayet stars are detected. This finding has an impact on the understanding the evolution of the massive stars in low-metallicity environment.
