Outstanding Performance of Recently Released Linseed (Linum usitatissimum L.) Variety (Yadanno) and Other Linseed Lines in South Eastern Highlands of Ethiopia

摘要

Yadanno is a common name for the linseed variety developed through hybridization and continuous selections using pedigree method. Yadanno was selected, developed and released by Kulumsa Agricultural Research Center for Arsi and West Arsi Zones and similar agro-ecologies of linseed growing areas of Ethiopia. Specifically, it was tested at Kulumsa, Bekoji, Asasa and Kofele for three years (2010/11 to 2012/13) and verified in 2014/15 at listed locations for 2016 official release. As a result, Yadanno consistently produced better mean seed and oil yields than the standard check (Kulumsa-1) and the local check over three years. Likewise, it proved to be resistant to wilt ( Fusarium oxysporum f.sp. lini ), powdery mildew (Oidium sp.) and pasmo (Septoria linicola) diseases. The results of the multi-location trials revealed that Yadanno was superior in seed and oil yields performance across years and locations. Besides, it is stable variety based upon different stability parameters.
