Mahoor, A New Barley Cultivar for Semitropical Dryland Conditions

Some parts of semitropical regions in Khouzestan, Fars, Kohgiloyieh-va-Boyrahmad, Lorestan, Golestan, Ardabil, Kermanshah and Boushehr provinces specified to spring barley cultivation which local or a few improved cultivars are grown there. Barley breeding activities in Dryland Agricultural Research Institute(DARI) are continuously undertaken in Gachsaran, Kouhdasht, Gonbad and Moghan to introduce new cultivars for these regions. Obtained results during 11 years (1993-2003) showed that genotype Wi2291/Wi2269//Er/Apm originated from ICARDA, had good adaptation, yield stability and good agronomic traits in dryland areas with semitropical climate. The average yield of this genotype in all locations was 3.556 tha-1 which was 12 percent more than the yield of Izeh as improved check. Higher thousand kernel weight (more than 10 gram in some locations) is a remarkable trait of this genotype. The new genotype is a spring type barley with an average plant height of 72cm and resistant to lodging. This genotype was introduced through Agricultural Extension, Education and Research Organization under the name of Mahoor in 2008
