introduction of new varieties of durum wheat by the private sector in cooperation with the international maize and wheat improvement center (cimmyt)

The cultivars introduced from among the improved genotypes of international cereal research centers (cimmyt and icarda) have played an effective role in increasing iran wheat yield. on the other hand, the bilateral cooperation between the country s research institutions by using the facilities of the private sector leads to the improvement and acceleration of the research findings. for this purpose, from the special gene treasury of durum wheat from the international wheat and corn research center (cimmyt), with the aim of obtaining new varieties of high-yielding durum wheat, a split plot experiment was conducted based on randomized complete block design with three replications, in the research farm of baladarband company and located in kermanshah. the main factor consisted of two levels of irrigation (stress and irrigation), and the secondary factor consisted of four genotypes of durum wheat d1, d2, d3, d4, and sana cultivar as a control. the results showed that genotypes d1 and d2 are suitable for drought stress conditions at the end of the season with a positive reaction to additional available water, and genotypes d3 and d4 produce better yield exclusively in drought stress conditions at the end of the season and have a negative response to irrigation at the end of the season.
