Abstract

Mahtab barley variety (line CB-84-10) was initially selected from International Winter Barley Crossing Block Nursery received from ICARD in 2001-2002 cropping season. During observational evaluation, preliminary yield trial and advanced yield trial during 2002-2005 cropping seasons based on its considerable grain yield compared to the other studied genotypes, this line was selected for final evaluation in the elite barley lines yield trial which was conducted in Karaj, Mashhad, Jolge rokh, Miandoab, Tabriz, Ardabil, Hamadan and Arak research stations during 2005-2007 cropping seasons. The average grain yield of Mahtab cultivar in this experiment was 7167 kgha-1, that was 591 kgha-1 (9%) higher than the grain yields of check variety Bahman. Mahtab has facultative growth habit, plant height of 88 cm, thousand kernel weight of 44 grams and exhibits lodging resistance and non-shattering rachis as well as wide adaptability across cold regions of the country. In addition, this variety has moderately-resistant (MR) to moderately-susceptible (MS) infection responses to yellow rust and powdery mildew and MR infection response to barley stripe and barley net blotch. The protein content of this variety is 11.5% that indicates its appropriate quality for animal feeding. Based on high biomass of Mahtab variety in the soft dough stage, this cultivar can be also used as green forage for animal feeding. Agricultural lands located in the cold regions of Alborz, Khorasan Razavi, Fars, East Azarbaijan, West Azarbaijan, Ardabil, Hamadan, Zanjan, Ghazvin, Markazi, Kurdistan, Kermanshah, Lorestan, Chaharmahal and Bakhtiari, Isfahan and Kerman provinces are appropriate areas for cultivation of the new cultivar.
