The mass-luminosity relation (MLR) for intermediate-mass stars is based on data on detached main-sequence double-lined eclipsing binaries (DM-DLEB). However, there is a notable difference between the parameters of B0V-G0V components of eclipsing binaries and those of single stars. Single early-type stars are rapid rotators, whereas tidal forces produce synchronous rotation in close binaries and all such pairs are synchronized, so components of close binaries rotate more slowly. As is well known, stellar rotation changes stellar evolution and the global parameters of a star. In this work we collect data on fundamental parameters of stars with masses m>1.5m_{sun}_. They are components of binaries with P>15d and consequently are not synchronized with the orbital periods and presumably are rapid rotators. These stars are believed to evolve similarly with single stars. Modern data on masses, absolute and bolometric luminosities, radii and temperatures of detached main-sequence double-lined eclipsing binary components (i.e. presumably slow rotators) are also collected. Mass-luminosity, mass-temperature and mass-radius relations of close and wide binaries are presented, as well as their Hertzsprung-Russell diagram.
