Data on 13 S2 and S3 lines from the synthetic variety BS5 and test crosses of these lines with BS5 and A632 X A639 were analysed. Results indicated that in early inbred generations, selection based on grain yield of lines per se would improve not only the productivity of lines, but also their combining abilities.
