Sadegh, a New Indian Mustard Cultivar Suitable for Drylands of Iran

Cultivar Sadegh was generated from inter-specific hybridization and subsequent backcrosses between Brassica napus and B. juncea genotypes in Dryland Agricultural Research Institute (DARI). After identification of low glucosinolate and low erucic acid lines among backcross families and also after evaluating of backcrosses in the preliminary trials, adaptability tests were conducted during 2008-2011 in Maragheh (East Azarbaijan), Kangavar (Kermanshah), Ghamloo (Kurdestan) and Shirvan (North Khorasan). Stability parameters showed that line DARI-4-2 with average of 700 (kgha-1) grain yield had the highest stability over years and locations. Quality assessments showed that two Indian mustard linesDARI-4-1 and DARI-4-2 were highly resistant to shattering and also had good oil quality compared to canola cultivars. After evaluation of promising lines under on-farm trials, it was concluded that Sadegh (line DARI-4-2) could be introduced as a suitable oil crop for drylands of the country.
