  • Wheat germplasm screening for stem rust resistance using conventional and molecular techniques
    (Czech Academy of Agricultural Sciences, 2011) Kokhmetova, A.; Morgounov, A.; Rsaliev, S.; Rsaliyev, A.S.; Yessenbekova, G.; Typina L.
    In Central Asia, stem rust (Puccinia graminis f.sp. tritici) causes considerable damage, especially during growing seasons with high rainfall. Ug99 is a race of stem rust that is virulent to the majority of wheat varieties. To develop disease-free germplasm, wheat material was screened using the predominant stem rust races of Kazakhstan and tested in two nurseries; CIMMYT-Turkey and the Plant Breeding Station at Njoro, Kenya. A total of 11 pathotypes of P. graminis f.sp. tritici were identified in Kazakhstan from the stem rust samples collected in 2008?2009. In particular, pathotypes TDT/H, TPS/H, TTH/K, TKH/R, TKT/C and TFK/R were highly virulent. Of the 170 advanced lines of wheat, 21 CIMMYT lines resistant to 5 aggressive Kazakhstani pathotypes of P. graminis were identified. A high level of resistance was observed in 11 wheat cultivars and advanced lines: Taza, E-19, E-99, E-102, E-572, E-796, E-809 (Kazakhstan), Ekinchi (Azerbaijan), Dostlik, Ulugbek 600 (Uzbekistan) and Umanka (Russia). Based on data obtained from Turkey-CIMMYT and the Plant Breeding Station Njoro, Kenya nurseries, out of 13 tested entries, 6 wheat breeding lines which were resistant to both stem and yellow rust and 10 wheat lines which showed high and moderate levels of resistance to Ug99 were selected. Using the sequence tagged site (STS) molecular marker Sr24#12, associated with Sr24/Lr24, seven wheat entries resistant to stem rust were identified. These results will assist breeders in choosing parents for crossing in programmes aimed at developing varieties with desirable levels of stem rust resistance in Kazakhstan and they will also facilitate stacking the resistance genes into advanced breeding lines.

  • 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.

  • Evaluation of grain yield stability, reliability and cultivar recommendations in spring wheat (Triticum aestivum L.) from Kazakhstan and Siberia
    (Journal of Central European Agriculture, 2006) Gomez-Becerra, H.F.; Morgounov, A.; Abugaliyeva, A.I.
    The investigation was carried out to determine the stability and adaptability patterns of a set of 40 promising spring wheat genotypes from Kazakhstan and Siberia evaluated in a multievironment yield trial across 22 environments. Some of the most widely known parametric stability parameters were used as well as the less frequently cited reliability index (I). Grain yield correlated significantly and positively with the stability parameters b and S2 and the reliability index (I); but did not correlate with AMMI ASV. However, the stability parameters failed in detecting adaptability patterns. In contrast, the reliability index (I) was probed to be more useful in supporting practical decisions. With regard to the genotypes, cultivars Lutescens 54, Lutescens 30-94, Lutescens 29-94, Tertsia, Omskaya 35, and Shortandynskaya 95 showed to be the widest adapted and the most reliable cultivars.

  • 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.

  • Spring wheat in Kazakstan: current status and future directions
    (CIMMYT, 1998) Morgounov, A.; Satybaldin, A.; Rajaram, S.; McNab, A.
    The Republic of Kazakstan is an important grain producer. Spring wheat constitutes 90% of total wheat production. The temperature profile, dry climate, and soil conditions in the main grain producing regions favor the production of high quality wheat grain. The quality of durum wheat varieties produced in Kazakstan was once unique in the world. The wheat of Kazakstan is highly valued on both the domestic and international markets for making bread, biscuits, and alcohol. Today the domestic market consumes only one third of Kazakstan's total wheat production; the rest is exported. Kazakstan is a full member of the Grain Trading Committee and has the status of an observer in the International Grain Council's Committee for Food Assistance. This is also the contribution of Kazakstan's agricultural scientists, who developed and released highly productive wheat varieties for the country's different climatic zones, organized seed production, and developed regional cultivation technologies. However, due to the strong competition on the international market, it is necessary to speed up the development and release of high yielding wheat varieties with good grain quality that are well adapted to the harsh soil and climatic conditions, pests, and diseases that prevail in our country. The quality of our bread wheat varieties must meet international standards so that we can sell Kazakstan grain on the international market. It is not possible to solve the problems of wheat production in Kazakstan without utilizing world experience and global plant genetic resources, and without cooperating closely with foreign scientists. This is why I support the development of a collaborative spring wheat research program with CIMMYT, which works under the auspices of the United Nations and cooperates with scientists from countries all over the world.
