摘　　要：“田润189”是河池市农业科学研究所以“河自BC-12”为母本,以“河自869”为父本选育组配的杂交组合。2019年、2020年均通过了广西玉米试验,667 m2产量幅度为378.3~662.8 kg。“田润189”植株持绿期长,第一叶鞘紫色,株型平展,穗筒型,籽粒黄色半硬粒型,穗轴白色;2019年粮用生育期春季平均为110 d、秋季平均为113 d,幼苗长势中上;在后期田间评定中抗(MR)纹枯病,中抗(MR)南方锈病,中抗(MR)大斑病,抗(R)小斑病,感(S)轮枝镰孢穗腐病,高抗(HR)轮枝镰孢茎腐病;在“河玉848”(生产试验代号)品质测定结果中,“田润189”品质指标优于国家食用玉米和饲料用玉米一级质量标准。“田润189”适应性广,春季气温稳定在12℃以上即可播种,秋季7月下旬至8月上旬均可播种。苗期注意防治小地老虎等地下害虫;大喇叭口时期应及时施肥;全生育期注意防治草地贪夜蛾,而玉米螟及玉米蚜虫等害虫可放赤眼蜂进行生物防治;根据种植目的适时采收。“Tianrun 189”is a hybrid combination of“Hezi BC-12”as the female parent and“Hezi 869”as the male parent by the Hechi Agricultural Science Research Institute.In 2019 and 2020,it passed the maize test in Guangxi,and the yield per 667 hectares was 378.3-662.8 kg.“Tianrun 189”plants stay green for a long period of time with purple first leaf sheaths.The plant type is flat and tubular,and its grain is yellow and semi-stiff with a white rachis.The average growth period of grain in spring is 110 d and 113 d in autumn.The seedlings grow moderately.In the late field evaluation,it showed medium resistance(MR)to sheath blight,medium resistance(MR)to southern rust,medium resistance(MR)to northern leaf blight,resistance to southern leaf blight,sensitivity(S)Fusarium verticillioide disease,high resistance(HR)to Fusarium graminearum.The quality of“Heyu 848”in the quality measurement results exceeded the national standards for fiest-class food corn and feed corn.“Tianrun 189”can be sown above 12℃when the temperature is stable in spring,and can be sown from late July to early August in autumn.Attention should be paid to the control of underground pests such as cutworm seedling stage.Fertilizer should be applied in a timely manner during the period of V12.Throughout the entire growth period,should be given pay attention to the biological control of corn grass armyworm,while insect pests such as corn borer and corn aphids can be controlled by trichogramma.Corn is harvested in a timely manner according to planting purpose.
