ABSTRACT: Segregating progenies for the flesh colour of tetraploid potatoes were developed by hybridization of contrasting parents Bareilly Red (Red skin, round shape, deep eyes, cream flesh with red broad vascular ring) and CP3770 (Red

skin, round shape, medium deep dark red eyes, yellow flesh). Molecular profiling (ISSR and SSR markers), agronomical performance and nutritional profiling were undertaken on 64 coloured progenies. A highly polymorphic and diagnostic SSR marker (STM2005) was identified in the parents for tuber flesh colour and accordingly it showed segregating profiles in the progenies. Advanced stage clones like MSP/15-26 (yellow flesh with red vascular ring), MSP/15-44 (Yellow flesh with red vascular ring), MSP/15-51 (red purple flesh), MSP/15-56 (yellow flesh with red vascular ring/medulla, multi-coloured chips) and MSP/15-64 (purple red scattered flesh) showed superiority for nutritional components and are potential clones for use as elite germplasm and release as variety under speciality potato sector.
