重庆成功育成两个高产优质玉米自交系品种

    市农业科学院昨日传出喜讯,我市再育成渝8954和渝38两个高产优质的玉米自交系品种,其最高亩产可达到500公斤以上,同时能够在生长状况下全程抗击青枯病、丝黑穗病等多种玉米常见病虫害。
  近年来,我市在水稻、玉米等农业领域共育成通过国家和重庆审定品种23个,且我市主要农作物自育品种的推广面积不断增大,使“渝育”品种的国内市场占有率不断提升,扩大了我市育种研究、成果转化等方面的影响力。但我市特殊的气候环境,使得我市玉米的种植面临着病虫害、高产不优质等困惑。对此,我市除了在甜糯玉米等品种上加大良种创新力度,在一些能够作为育种材料的自交系玉米品种上也不断进行创新改良。
  而我市最新育成的渝8954和渝38这两个自交系品种,就实现了高配合率、高抗病性、高自产量的“三高”目标。农科院玉米研究所所长杨华说,目前,该品种已与玉米渝39、渝单19、渝单25等国家审定的优质高产品种配种,玉米亩产达到500公斤以上。其高抗病性的特点,能使其在重庆高温时间长等环境下,抗击大小斑病、青枯病、丝黑穗病等玉米常见疾病。此外,这两种自交系玉米品种还能实现高自产量,即在不杂交配种的情况下,还能使自身的亩产量达到200公斤以上。
  据悉,目前这两个品种已在四川、贵州等七个省市开展了大面积推广种植。
