Abstract

Avan (line DW-93-5), a new durum wheat cultivar, was initially introduced as a breeding line through 43rd International Durum Yield Trial Nursery (43rd IDSN) received from the International Maize and Wheat Improvement Center (CIMMYT) and was evaluated in two research stations of Dezful and Darab in warm agro-climate zone of Iran. In this step, DW-93-5 (Avan) was selected for the further studies based on its high grain yield (5834 kgha-1). This line with 6922 kgha-1 average grain yield was selected in the regional preliminary yield trial in 2012-2013 cropping season. Line DW-93-5 had an average grain yield of 8094 kgha-1 in the advanced yield trials and was selected for the further evaluations. The regional elite yield trial was conducted in four stations of Ahvaz, Darab, Dezful and Khorramabad in 2014-15 and 2015-16. This line with 6449 kgha-1 had higher yield than Behrang check cultivar with grain yield of 5959 kgha-1 and was selected as superior line based on its grain yield and yield stability. Avan also has high quality of semolina, high protein content (12.4%). The results of on-farm trials showed that this cultivar exhibited a higher grain yield than Shabrang and Behrang in Kerman, Kermanshah and Khoozestan provinces. In total, based on its high grain yield, yield stability, quality of semolina and its good level of resistance to yellow and leaf rusts, line DW-93-5 was released as a new durum wheat cultivar with the name of “Avan” for warm agro-climate zone of Iran.
