SELECTION MODEL IN RICE (ORYZA SATIVA L.)

Published on

The study based on multiple selection criteria in F2 population of six rice crosses revealed
the desirable responses in most of the characters under study in F3 generation. However,
nonsignificant values of intergeneration rank correlation and best vs worst variance ratio
indicated the absence of response to selection on the basis of grain yield per se. Further
selections in two crosses, N22 X FH109 and N22 X lET 1444, are expected to give better
responses in succeeding generation.
