Abstract only
Drought is the most important environmental constraint that reduces the crop yield in Central West Asia and North Africa (CWANA). Because it is not predictable in the region that makes it difficult to take measurements in advance or develop drought genotypes for a certain type of drought as it may come in early or late growth stage of the crop. Winter Facultative Wheat (WFW) has been grown around 18 million ha in CWANA, starting from Atlas Mountains in North Africa to highlands of Afghanistan where primary target of the International Winter Wheat Improvement Program (IWWIP). IWWIP is a joint program carried out by Turkey, CIMMYT and ICARDA that operates since 1986 and develops and provides WFW germplasm to about 150 collaborators in around 50 countries in the world. Within 25 years, more than 40 cultivars selected from the germplasm provided by IWWIP have been released in 12 different countries covering around 1.7 million ha. One of the main aims of the IWWIP is to develop drought tolerant germplasm that performs well under CWANA agroecological conditions and provide that germplasm to its collaborators. For this purpose, one site in each location, Konya and Eskisehir in Turkey has been established to test the material under field conditions. The diverse and advanced germplasm have been planted in the fields of each location after safflower. Safflower consumes most of the soil moisture that allows us to control the soil moisture by applying drip irrigation. While grain yield difference of same genotypes between Supplemental Irrigation (SIR) and Rainfed plots is 2-3 times in 2009-2010 growing season, dry season, it is around 40-50 % in 2010-2011 growing season, rainy year. The other approach for selecting drought tolerant germplasm is to test the material in multilocation trials where the amount and distribution of precipitation differs in time and space. By doing so, IWWIP compiles diverse and advanced germplasm and distributes to IWWIP collaborators.
