Abstract
Field pea (pisum sativum L.) variety ‘Bursa’, with a pedigree (EH 04053 × EH 04051) and breeder ID designation of ‘EH05027-2’ was released in 2015 for highland areas of the country. The variety has been registered by Kulumsa Agricultural research center and it was tested at better representative environments (Kulumsa, Bekoji, Asassa, Kofele, Adet, Adadi, Jeldu and Sinana) representing mid-highland and highland (1800 to 3000 mean above sea level) agro-ecologies during 2012- to 2013- cropping season. The variety produced 2.78% and 3.09% seed yield advantage over the standard checks Burkitu and Letu, and produced 8% seed size advantage over the shiro-type standard check Letu respectively. It also had comparable resistance/tolerant level to major field pea diseases as checks. The variety is mainly characterized by superior mean grain yield as compared from standard check both Burkitu and Letu based on different yield measurement and stability testing parameters across location and over year yield recorded data from national variety trials.
