An attempt was made to develop dwarf high yielding scented varieties with long slender grains. Crossing was made between high yielding lines and Basmati rice varieties. Desirable lines were identified from the segregating generations of IR30 x Basmati 370 cross only. Fifty two F₄ lines, selected from sixteen F₃ families, were evaluated for nine biometrical characters viz. panicle number plant-1, panicle weight, panicle length, grain number panicle^-1, grain length (L), grain breadth (B), grain L:B ratio, 1000 grain weight and grain yield plant^-1. The analysis of variance revealed significant differences among the lines for all the Parameters studied. Four lines showed significantly superior performance in respect of grain yield and some other yield related characters. Mean grain length of the selected lines was 7.45 mm and nine lines showed significantly superior performance in respect of grain yield and some other yield related characters. Mean grain length. More than sixty percent lines had>4.0 grain L:B ratio. High genotypic coefficient variability(GCV) and Phenotypic coefficient variability (PCV) were observed for grain yield plant-1, grain number panicle^-1, panicle weight and panicle number plant-1. High heritability was observed for panicle weight, grain number panicle^-1, grain length, grain L:B ratio, 1000 grain weight and grain yield plant^-1 while panicle number plant^-1, panicle length and grain breadth and moderate heritability. Grain yield plant^-1 showed maximum genetic advance as percentage of mean followed by panicle weight, grain number panicle^-1, 1000 grain weight and panicle number plant^-1, respectively.
