  • Yield stability analysis of winter wheat genotypes targeted to semi-arid environments in the international winter wheat improvement program
    (Global Science Books, 2012) Sharma, R.; Morgounov, A.; Braun, H.J.; Akin, B.; Keser, M.; Kaya, Y.; Khalikulov, Z.I.; Van Ginkel, M.; Yahyaoui, A.; Rajaram, S.
    Improved winter wheat (Triticum aestivum L.) cultivars for semi-arid environments in Central and West Asia are needed to increase wheat productivity. This study was conducted to determine the performance of winter wheat genotypes for semi-arid environments, analyze their stability, and identify superior genotypes that could be valuable for winter wheat improvement or varietal release. One hundred thirty three advanced breeding lines and four check cultivars were tested over a 6-year period (2005-2010). Grain yield stability and agronomic traits were analyzed. Many genotypes produced higher grain yield and were more stable than one or more of the checks in each year. By and large, different genotypes showed superior performance under low and high productive environments, demonstrating their specific adaptability. However, 11 out of 30 highest yielding genotypes were common both under low and high productive environments. This shows that while in general different sets of genetic materials are needed under strictly semi-arid and irrigated environments, a few lines targeted towards stressed conditions possess yield plasticity resulting in superior performance both under dryland and irrigated conditions.

  • International cooperation for winter wheat improvement in Central Asia: Results and perspectives
    (The Scientific and Technology Research Council of Turkey, 2005) Morgounov, A.; Braun, H.J.; Ketata, H.; Paroda, R.S.
    Crop production in Central Asia has long history going back to 2000-3000 years BC. The farming in the past was mainly concentrated in irrigated areas along the two main river basins: AmuDarya and Syr-Darya. Wheat cultivation in Central Asia in the 20th century concentrated primarily in rainfed area. The breeding work conducted at several stations in the region was initially based on local landraces and resulted in adapted varieties. However, the breeding work was not consistent and interrupted. Since 1991 the wheat became an important crop due to food security concern and replaced cotton in some areas. The modern varieties developed in the region are well adapted and combine yield potential, grain quality and disease resistance. At the same time a number of foreign varieties from Mexico, Russia, Turkey, USA and other countries are cultivated in the region. The international cooperation with centers like CIMMYT and ICARDA resulted in the establishment of international network of researchers sharing the germplasm, knowledge and experience. New jointly developed varieties are being officially tested and some already reached the farmers. Support provided to wheat variety development and promotion in the region from international agencies and organizations like FAO, German Agency for Technical Cooperation, US Department of Agriculture, Washington State University, Winrock International, and others is fundamental for the wheat grain production in Central Asia.
