Abstract
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. Keywords : Edible Oil; Yadanno ; Linseed; Variety registration DOI : 10.7176/JBAH/9-7-05 Publication date : April 30 th 2019
Highlights
Oil crops occupy third position following cereal and pulse crops in the agricultural economy of Ethiopia
Among oil crops linseed (Linum usitatissimum L.) is one of the ancient oilseeds cultivated for oil, food and fiber (Lay and Dybing, 1989; Nozkova, et al, 2016)
Area and production of linseed dramatically decreased by 125% and 78% when we compare data of last eight years data (CSA, 2009; CSA 2017), its productivity improved by 27%
Summary
Oil crops occupy third position following cereal and pulse crops in the agricultural economy of Ethiopia. This paper presents the overall performances of the recently developed and released linseed variety (Yadanno) with the aim to play a significant role in solving the chronic edible oil shortage in the country, and to exploit its linseed production and productivity capacity for domestic uses and export purposes. AGRONOMIC AND MORPHOLOGICAL CHARACTERISTICS In an attempt to develop Yadanno, higher seed yield, oil content and resistance to major linseed diseases were important traits of consideration. YIELD PERFORMANCE Considering the overall seed yields, Yadanno (H31 X Belay-96-208) produced better seed yield (2246 kg/ha) than the standard check Kulumsa-1(1772 kg/ha) across locations (Table 2 & 3). This variety consistently performed better than the checks over three years.
