Theoretical isochrones, in the interval 3 to 25 106 y., have been obtained from the grid of stellar models with mass loss computed by Maeder (1980, 1981). They cover the main sequence evolution, the red supergiant region and the first blue loop. These isochrones have been compared to composite colour magnitude diagrams of young open clusters drawn by Mermilliod (1981).
