国际冬小麦观察圃试验结果分析与利用评价

Analysis and Evaluation of International Winter Wheat Observation Nursery

1997—2004年甘肃省冬小麦研究所引进国际冬小麦改良项目(IWWIP)半干旱地冬小麦观察圃、水地冬小麦观察圃和兼性及冬小麦观察圃等试验材料17套2091份。通过试验发现在IWWIP观察圃中有许多材料高抗条锈病,丰产性好,抗旱性强,品质优良。但多数材料植株偏高,穗部性状较差,抽穗期偏晚,不宜在生产上直接利用。作为品种资源,育种中对综合性状表现优良的材料可重点进行研究利用;对某些方面表现突出的材料,也可根据材料特点有针对性地加以利用。

17 sets trail 2091 entries material of International Winter Wheat Program （IWWIP）were introduced by our institute from 1997 to 2004, include winter wheat observation nursery for irrigated areas, winter wheat observation nursery for semi-arid areas, facultative and winter wheat observation nursery. The result shows that there are many material of high resistance to stripe rust, high yield, fight a drought and high quality in International Observation Nursery. Majority are high height, late heading, and small spike. They were not used in production. They may be used as resources. Good material that their synthesis characters are good, and may be used as stress. Those materials which are outstanding on some sides should be used by their trait.
