摘 要 ：对MZZ3（改良中综3号）、MZZS4（经4轮MS1改良的中综4号群体）完成了2轮改良半同胞（HS）相互轮回选择。结果表明，两群体以籽粒产量为主要选择目标，经两轮改良HS相互轮回选择，与各测验种间的测交组合产量、杂种优势都获得了逐轮提高。测交组合产量每轮增益（△G）在285 kg/hm²（5.5%）到688 kg/hm²（13.0%）之间

Abstract:Tow cycles of modified HS reciprocal recurrent selection aiming at improvement of grain yield in MZZ3 and MZZS4 maize (Zea mays L.) populations were completed in northern China. The objective was to evaluate improvement effects for MZZ3 and MZZS4 via NCⅡ mating design at four locations in 2002. Ana
