摘　　要：优良玉米自交系新01A3及其姊妹系新6是以优良玉米杂交种为基础材料,利用热带种质资源8085泰杂交,用昌7-2回交后,经多代自交选育而成的优良自交系,属于塘四平头类群,具有中早熟、高抗、高配合力、质优等突出优点。直接利用新01A3、新6及其改良系,选育出多个通过省审和国审玉米杂交种,其中新单68为河南省第一批审定机收组品种,新单58、新单65、新单68、新单88为国审机收品种,适宜黄淮海夏玉米种植,适宜玉米全程机械化操作。新单33、新单36、新单38、新单61及豫单606为普通玉米品种,具有优质、高产、高抗等特性。Xin01A3 and sib-line Xin 6 were both elite inbred lines in maize,which were breeding by used maize hybrid(production test variety A in 2000)as basis material,hybridization with the tropical germplasm 8085 Thai,backcross with Chang7-2,and then selfing through many generations.Xin01A3 and Xin 6 belong to TangSiPingTou heterosis group,with the characters of mid-early maturity,high resistance,high combining ability,good quality and so on.Directly using Xin01A3,Xin 6 and their improved inbred lines as parents,many excellent maize hybrids were breeding which were approved by the provincial and national test.Among them,Xindan 68 is the first group variety suitable for mechanized harvesting approved by Henan province.Xindan 58,Xindan 65,Xindan 68 and Xindan 88 are all approved by the national test,these varieties are suitable for Huang-huai-hai summer maize planting,and suitable for mechanized operation in the whole maize production.Xindan 33,Xindan 36,Xindan 38,Xindan 61 and Yudan606 are all ordinary maize varieties with the characteristic of good quality,high yield,and high resistance.
