Pedigree method was adopted for development for Vallabh Basmati-22 and Vallabh Basmati-23, the varieties of specialty rice. The slow growing segregants of a cross P1121xType3 were selected on the basis of disease resistance and grain quality. As a consequence of evaluation of such selections in following generations the improved varieties of Basmati rice were developed. Introgression of genes for dwarfism and resistance against blast and blight diseases was evaluated in artificial epiphytotic condition followed by confirmation using respective molecular markers.
