TextPublication details: Tbilisi (Georgia) CIMMYT : 2004Description: p. 236Subject(s): Summary: Diverse soil-climatic conditions of Azerbaijan require widely adapted, high-yielding wheat varieties ofthe winter/facultative growth habit combining high yield with high drought tolerance and resistance to fungal diseases. Obtaining of widely adapted vari- eties is also important because of high variability of the crop management practices and conditions in Azerbaijan varying from dryland to irrigated systems. Right choice of the variety and its allocation in terms of environments and farming systems contributes to increase of grain output in the country. The objective of the present study is to evaluate adaptability of improved germplasm to various agro-ecological conditions of Azerbaijan. For this purpose, a multi-location trial ofthe selected lines and varieties was established in 5 different soil- cljmatic areas of Azerbaijan: Tartar Zonal Trial Station (irrigated), Gobustan ZTS, Jalilabad ZTS, Zagatala ZTS and Shekj Base Site (all rainfed). Three-year data has already been collected. Each variety was planted on a 5-m2 plot in three replications. The trial material included 3 check varieties (used in different regions), 4 advanced varieties and 11 lines of bread wheat, 1 released and 1 advanced variety of triticale. The obtained data showed that the bread wheat check varieties, which are widely cultivated in the republic, were affected by yellow rust (20MS- 80S) in all regions. In contrast, advanced varieties Azamatli 95, Gobustan, Nurlu 99 and Aran showed resistance to yellow rust (0-20 MR). Under irrigated conditions (Tartar ZTS), advanced variety Gobustan was found rather susceptible to yellow rust (30 MS). The reactions of the entries to yellow rust varied from R to 40S, depending on the environment. The responses of released triticale variety Samur and advanced variety Shirvan to yellow rust ranged within 20MR- 70S and 1 OMR-90S respectively. The table below shows that advanced bread wheat variety Azamatli 95 produced high yield under the both irrigated and rainfed farming systems. The other promising bread wheat variety Nurlu 99 demonstrated high performance under the irrigated conditions mostly. New promising variety Aran has demonstrated yield advantage under the both irrigated and humid rainfed conditions. The obtained data allow for identification of the best lines and varieties per the most important traits and performance in various environments for their subsequent adoption. In addition, based on the trial data establishment of a small-scale seed production ofthe selected promising varieties is possible at the local level prior to their wide introduction into industrial practice in order to facilitate their fast promotion.
