Q6优28是重庆中一种业有限公司和重庆市农业科学院选育的三系籼型高产杂交水稻新组合,2016年通过国家农作物品种审定委员会审定(国审稻2016016)。不育系Q6A对授粉期温度敏感,35℃以上高温影响不育系结实。通过对近3 a Q6优28在不同区域制种试验,总结了通过基地选择、始穗期安排、群体构建、肥水管理、“九二○”施用、病虫防治等方面控制获得高产优质种子的制种技术。为Q6优28的大面积生产提供依据。
Q6 You 28 is a new combination of three lines indica high yielding hybrid rice selected by Chongqing Zhongyi Industry Co., Ltd. and Chongqing Academy of Agricultural Sciences. In 2016, it was approved by National Crop Variety Approval Committee (State Examination Rice 2016016). The sterile line Q6A is sensitive to the temperature during pollination period. The high temperature above 35 ℃ affects the CMS lines. Through the test of seed production in different regions in recent 3 years, we summarized the control of high yield and quality through base selection, initial heading stage, population construction, fertilizer and water management, application of “920” and pest control Seed production technology. Provide the basis for large-scale production of Q6 excellent 28.
