Abstract: Three cycles of half-sib recurrent selection (HS) have been completed in a maize (Zea mays L.) population zhong zong 2(ZZ-2). The results indicated that this mathod was equally effective in improving both grain yield and general combining ability (GCA). The increase per cycle in grain yield was 7.4%

Key words: Maize, Population improvement, Half-sib selection
