“…This is particularly encouraging, considering that the superior experimental genotypes differed in pedigree; and therefore probably genotype, providing further opportunities for genetic gain through recombination of superior alleles. Previous studies suggested that since the winter wheat environments in Central and West Asia vary greatly (Braun et al 1998;Trethowan et al 2001Trethowan et al , 2003Lillemo et al 2004Lillemo et al , 2005, diversity in widely adapted wheat cultivars is needed for developing high yielding stable genotypes for the region (Ö zgen 1991; Morgounov et al 2005). Besides being higher yielding and more stable than the checks, the experimental genotypes were selected for resistance to rusts and other diseases prevalent in Tables 1 and 2 for full names of the locations and genotypes, respectively) target countries in the region, as well as for improved quality traits (information available on www.iwwip.…”

“…There are a number of parents in the pedigrees of the superior genotypes that possess combinations of high yield and resistance to leaf rust and stripe rust (Singh et al 2000). Such genotypes are especially valuable considering that leaf rust and stripe rust are the most important disease constraints in many of the target countries (Braun et al 1998). …”

“…Braun et al (1998) outlined the priorities for winter wheat breeding in Central and West Asia. High and stable yield, wide adaptation, drought tolerance, grain quality, resistances to stripe rust (caused by Puccinia striiformis), leaf rust (P. triticina) and stem rust (P. graminis tritici), cold tolerance and winter hardiness are important traits needed in winter wheat cultivars for the region (Braun et al 1998;Morgounov et al 2005). IWWIP, in collaboration with national partners, has been working to meet the winter wheat germplasm and cultivar needs, and successes were outlined by Morgounov et al (2005).…”

Improved winter wheat (Triticum aestivum L.) cultivars are needed for the diverse environments in Central and West Asia to improve rural livelihoods. This study was conducted to determine the performance of elite winter wheat breeding lines developed by the International Winter Wheat Improvement Program (IWWIP), to analyze their stability across diverse environments, and to identify superior genotypes that could be valuable for winter wheat improvement or varietal release. One hundred and one advanced winter wheat breeding lines and four check cultivars were tested over a 5-year period (2004)(2005)(2006)(2007)(2008). Grain yield and agronomic traits were analyzed. Stability and genotypic superiority for grain yield were determined using genotype and genotype 9 environment (GGE) biplot analysis. The experimental genotypes showed high levels of grain yield in each year, with mean values ranging from 3.9 to 6.7 t ha -1 . A set of 25 experimental genotypes was identified. These were either equal or superior to the best check based on their high mean yield and stability across environments as assessed by the GGE biplot analysis. The more stable high yielding genotypes were ID800994.W/Falke, Agri/Nac//Attila, ID8009 94W/Vee//F900K/3/Pony/Opata, AU//YT542/N10B/ 3/II8260/4/JI/Hys/5/Yunnat Esskiy/6/KS82W409/Spn and F130-L-1-12/MV12. The superior genotypes also had acceptable maturity, plant height and 1,000-kernel weight. Among the superior lines, Agri/Nac//Attila and Shark/F4105W2.1 have already been proposed for release in Kyrgyzstan and Georgia, respectively. The findings provide information on wide adaptation of the internationally important winter wheat genotypes, and demonstrate that the IWWIP program is enriching the germplasm base in the region with superior winter wheat genotypes to the benefit of national and international winter wheat improvement programs.

The International Winter Wheat Improvement Program (IWWIP)—a collaboration between the government of Turkey, the International Maize and Wheat Improvement Center (CIMMYT), and the International Center for Agricultural Research in the Dry Areas (ICARDA)—develops and globally distributes improved winter wheat (Triticum aestivum L.) germplasm. The Winter Wheat Eastern European Regional Yield Trial was conducted by IWWIP during 1998–2005 using elite lines and varieties from IWWIP, Eastern Europe (EE), the United States, and Central and West Asia (CWA). This study analyzed data to identify superior genotypes and key locations that could be useful for future international collaboration on winter wheat. Grain yield and agronomic traits of 422 elite breeding lines and new varieties from 17 countries were evaluated across 39 locations. Superior genotypes and key environments for grain yield were determined using genotype and genotype × environment biplot analyses. Many superior genotypes were identified for both EE and CWA, and 11 genotypes showed high, stable grain yield across the regions. The most representative and discriminating sites for grain yield were Konya and Eskisehir, Turkey (overall); Edirne, Turkey (CWA); and Dobrich, Bulgaria (EE). These findings represent a comprehensive analysis of yield and stability of a large, globally important set of winter wheat genotypes and growing locations, which may be useful for national and international winter wheat improvement programs.
