The present work was carried on Bougainvillea spp at the Experimental Farm of Agriculture, Zagazig University, during the two successive seasons of 2005 and 2006.The aim of this investigation was to study the response of two cultivars of Bougainvillea; i.e, B. glabra (white flowering variety) and B. buttiana Mrs Butte (red, flowering variety) to physical mutagen gamma, ray (0.0, 2.0, 4.0 and 6.0 Krad.) and chemical mutagen (N-nitroso-N methyle Urea) NMU 0.000, .010, 0.015, 0.020 and 0.025% . Mutations in growth traits, i.e., (compact plants and dwarfness), bracts colour, delay flowering, flower bearing, leaf shape and chlorophyll mutation, flower cluster, length and fasciata were appeared. In M2, NMU was efficient than gamma radiation and the variation and the mutations in B. buttiana Mrs Butte (red flowering variety) were higher than that of B. glabra (white flowering variety).
