Abstract
Evaluation of S lines per se is a popular method of recurrent selection for improving quantitatively inherited traits in maize. To evaluate the efficacy of S, line recurrent selection for yield and yield related traits in maize under maydis leaf blight (MLB) stress, one cycle of S line recurrent selection was conducted in maize variety Sarhad White (SW) at the Plant Breeding and Genetics Research Farm, NWFP Agricultural University, Peshawar during 2007. In spring (March-June), the base population from the third cycle of S line recurrent selection was sown in the field and manual self pollination was carried out for S line production. During the following season (July-October), the S, lines were evaluated for resistance to MLB under artificial inoculation for yield and yield components. Highly significant differences (P
