Single and multi source selection indices were developed in M-93 generation `M' strain of WLH using the traits AFE, PEP, PBW, MBW and EW in different combinations. The study revealed superiority of multi source selection indices in improving expected genetic gains of component traits and index efficiency {rTi). However, aggregate economic gain (o H) did not improve in all the indices when supplemented with additional sources of information. Supplementingadditional sources of information only to lowly heritable trait was more useful
