Abstract
Truncation selection in F4 and F5 Iines derived from F2 population of rice plant was conducted to cornpare the expected with observed genetic gains. The expected and observed direct responses to selection were substantially large in all traits measured. Correlated responses obtained in all traits measured were smaller than direct responses. There was comparatively good agreement between the expected and observed responses. It is estirnated that an expected genetic gain is available to develop an effective selection method in the rice breeding programme.
