title: [Study on variety test of Iris tectorum new variety of CSG1].
abstract: OBJECTIVE
  Iris tectorum new varieties of CSG1, CSG2, CSG4, CSG5, CSG6, CSG7, CSG8 and CSG9 were bred by system selection from abundant germplasm resources.
  
  
  METHODS
  Taking conventional variety as the control, comparison test for these new varieties was arranged in Shuangliu, Zhongjiang, Maoxian, Renshou and Anxian in Sichuan. Plot yields were measured after harvesting, yields per mu were calculated and the data were analyzed with DPS 9.50 software.
  
  
  RESULTS
  CSG1 had the highest yield which was significantly higher than the control and other varieties. This new variety had passed through the field identification by Sichuan Provincial Crop Variety Approval Committee in 2013 and would be applied for approval in 2014.
  
  
  CONCLUSIONS
  CSG1 is the first batch of Iris tectorum new variety identified by domestic authority and has great promotion potential.
