2017-2018年西藏春小麦新品种(系)比较试验与评价分析

Comparison and Evaluation of New Varieties(Series) of Spring Wheat in Tibet from 2017 to 2018

筛选适合西藏一江两河地区种植的春小麦新品种。选择13个新品种(系),与对照品种山春一号和藏春951进行对比试验,以生育特性、抗病性、考种结果及产量性状为依据,筛选适合西藏一江两河地区种植的高产优质和综合抗性强的春小麦新品种。结果表明,综合各因素表现较好的品种(系)依次为品比11、品比18、品比24,产量分别较CK1和CK2增产14. 5%、19. 5%,9. 9%、14. 7%和0. 7%、5. 2%,增产显著。其它没有达到显著水平。由此可得,品比11、品比18、品比24这3个品种(系)综合抗性好,丰产性好,产量稳定,整齐度好,增产潜力大,可推荐到下一轮的全区区域试验。

The present paper aims to select new varieties of spring wheat suitable for planting in Tibet,one river and two rivers. 13 new varieties( lines) were selected and compared with the control species Shanchun No. 1 and Zangchun No. 951,based on fertility characteristics,disease resistance,seed test results and yield traits. New spring wheat varieties with high yield,high quality and strong comprehensive resistance suitable for planting in two rivers and one river areas of Tibet were selected. The results showed that the varieties( lines) with better performance of various factors were in order of grade ratio 11,grade ratio 18,and grade ratio 24. The output increased by 14. 5 %,19. 5 %,9. 9 %,14. 7 %,0. 7 %,and 5. 2 %,respectively,compared with CK1 and CK2,which increased significantly. Others did not reach significant levels. It is concluded that Pin ratio 11,Pin ratio 18,Pin ratio 24,these three varieties( lines) have good comprehensive resistance,good yield,stable yield,good tidiness,and great potential for increasing production. They are recommended to the next round of regional trials.
