摘要/Abstract

摘要： 用半姊妹轮回选择法完成了对中综2号三轮改良，结果表明：该法对群体产量和配合力均有显著的改良效果。经三轮选择后平均每周期获得量为7.4；一般配合力从C0的-10 081增长到C3的15.924。二者每周期的获得量与选择轮数之间均呈显著的正相关。本研究第一轮的选择用遗传基础广泛的非亲缘综合种做测验种，二、三轮的选择用自交系

关键词: 玉米，群体改良，半姊妹轮回选择

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
