Analysis of Characteristics and Promotion of Approved Wheat Varieties in Southern Xinjiang During 2009-2018
The study clarified the characteristics of the varieties approved in the regional trials of winter wheat in southern Xinjiang since the new century,in order to provide a reference for the approval and introduction of varieties in the region.Based on the varieties that participated in the South Xinjiang regional trial of the autonomous region and approved from 2009 to 2018,the yield,some agronomic characters,disease resistance and popularization were analyzed.The result showed that yield per unit area of varieties approved in the past decade was concentrated at 450～500 kg/hm2,and the yield of the approved varieties increased significantly compared with the control variety.In terms of agronomic traits,there are extra early maturing varieties compared with the control Xindong No.20.The plant height and 1 000-grain weight of the approved varieties are higher than those of the control Xindong No.20,and the number of kernel per spike and volume weight are lower.Six varieties were popularized after approval.The annual planting area of two varieties exceeded 60 000 hm2,and the annual planting area of one variety reached 67 000 hm2.The promotion of introduced and approved varieties is low,and it is necessary to introduce varieties based on regional needs to increase the contribution of introduced varieties to regional industrial development.The variety approval process has been basically completed,but the quality indicators need to be further optimized.
