A rotor blade (10) for a gas turbine includes a blade airfoil (11), a blade tip (15), a blade root (14), and a platform (12) which is formed between the blade tip (15) and the blade root (14), and is assembled from a plurality of individual sections (16, 17, 18), the material of which is adapted in each case to the intended purpose of the individual section concerned. With such a rotor blade, a simplified production is achieved as a result of each of the individual sections (16, 17, 18) from the dimensions being significantly smaller than the assembled rotor blade (10).
