International Winter Wheat Improvement Program (IWWIP) was established in 1986 between the Government of Turkey and CIMMYT with three main objectives: (1) develop winter/facultative germplasm for Central and West Asia, (2) facilitate global winter wheat germplasm exchange, and (3) training wheat scientists. ICARDA joined the program in 1991 making it a three-way partnership that continues to work effectively. The germplasm developed by IWWIP as well as the winter wheat cultivars and lines received from global cooperators are assembled into international nurseries. These nurseries are offered annually to public and private entities (IWWIP website) and distributed to more than 100 cooperators in all continents. IWWIP impact has primarily been in new winter wheat cultivars combining broad adaptation, high yield potential, drought tolerance and disease resistance. A total of 93 IWWIP cultivars have been released in 11 countries occupying annually an estimated 2.5–3.0 Mha. IWWIP cooperation with researchers in Turkey, Central and West Asia and several US universities has resulted in a number of publications reviewed in this paper. Important IWWIP impacts include national inventories of wheat landraces in Turkey, Tajikistan and Uzbekistan, their collection, characterization, evaluation and utilization.

于2005—2006年在中国科学院封丘农田生态实验站研究了不同水分处理下冬小麦光合产物分配格局及其动态。实验设全生育期干旱处理和充分供水处理以及干旱后拔节期、孕穗期、开花期复水处理。结果显示:不同生育期复水对冬小麦由于干旱胁迫引起的生物量下降有补偿作用;干旱和复水能改变器官水平上光合产物的分配格局;干旱胁迫引起叶、穗分配降低,并使茎、叶鞘和根分配指数上升;拔节期复水使叶光合产物分配指数增加、茎分配指数下降;孕穗期和开花期复水能提高光合产物在茎和穗中的分配;不同时期复水对干旱胁迫引起的产量下降均有不同程度的补偿作用,拔节期复水主要提高小麦单株穗数、孕穗期和开花期复水以提高千粒重为主。

研究选用19个冬油菜早熟品种和1个春油菜品种进行小区分期播种试验,探索南方冬油菜早熟品种的生长发育特性。结果表明,综合考虑播种期与单位面积产量,冬油菜早熟品种全生育期应控制在180 d左右;应选择春性、对光温反应较迟钝的早熟品种;播种期应安排在10月中下旬,这样既可防止早花,又可确保油菜在次年4月中下旬成熟;早熟品种的生育特性优于半冬性中熟品种,一般苗期约40 d,蕾苔期约70 d,开花期约40 d,成熟期约30 d;出苗-终花天数与出苗-成熟天数呈正相关(r≥0.90)。青海春油菜品种属春性、弱感光类型,可作冬油菜早熟品种应用,尤以苗期较长、蕾苔期与开花期较集中的品种为佳。

Effects of urban river conditions on phytoplankton community were investigated. Nitrate utilization and hydrodynamic condition affected phytoplankton distribution. A winter bloom was induced by abundant ammonia, total phosphorus and organic matters. The diatoms and euglenoids dominated in an urban beheaded river ecosystem.
