IWWIP冬小麦优良品系产量试验结果分析及利用评价

Analysis and Valuation on the Results of Winter Wheat Elite Yield Trial of IWWIP (The International Winter Wheat Improvement Program)

2004年兰州商学院小麦研究所引进国际冬小麦改良项目(IWWIP)半干旱地和水地兼性及冬小麦优良品系产量试验(8THEYT-SA,2004—2005和9THEYT-IRR,2004—2005)两套。每套试验实际参试品种(系)20个。试验结果表明,旱地试验中9906、9914、9916、9920和9921等5份材料在生产上有直接利用价值。水地试验中9806和9825等2份材料虽然产量低于对照,但与对照的产量差异不显著,可以考虑在生产上直接利用。试验中对在不同方面(抗锈性、抗旱性、丰产性和品质等)表现突出的材料,应扬长避短进行研究利用。

8^TH Facultative and Winter Wheat Elite Yield Trail for Semi-Arid Areas and 9^Th Facultative and Winter Wheat Elite Yield Trail for Irrigated Areas of The International Winter Wheat Improvement Program were introduced by our institute in 2004. 20 advanced wheat lines were on each site. Results show that 9906, 9914, 9916, 9920 and 9921 of Semi-Arid can be used in wheat production. 9806 and 9825 of irrigated may be used in production, though their yields are lower than Local cheek, and yield diversity isn＇t remarkable to local cheek. Those are good at yellow rust resistance, drought resistance, high yield and quality, will be studied and used by material character.
