An Overview of Chickpea Improvement Program of Ethiopia
Introduction ■ Chickpea is grown by over 1 million households on 13.2% of the total crop acreage and forms 14.8% of the total production in Ethiopia
■ The current national chickpea productivity is 1.91 t/ha, way lower than the crop potential of 6t/ha
■ Some of the challenges in chickpea production include:• use of low yielding local landraces• susceptibility to a/biotic stresses• poor crop management practices • use of low quality seed
■ The national chickpea crop improvement program works with local and international partners to address these constraints.
Methods ■ The crop improvement program uses the following approaches
• Collection of local germplasm and selection,• Germplasm introductions (ICRISAT through TL I, II & II/ICARDA)
■ Hybridization followed selection ■ Preliminary variety trials ■ National variety trials ■ Variety verification trial ■ Lines that successfully go through these processes are released as new varieties and recorded in the national register.

Results ■ The chickpea improvement program released 24 improved varieties (17 national and 7 regional)
■ The released/pipeline varieties have traits such as
• large seed (64 g/100 seed weight)• Disease resistance (Ascochyta blight/Fusarium wilt)• Drought tolerance (MABC)• Early maturing• High yielding• Machine harvestable• Heat tolerant
■ The average yield gain due to these varieties is 2-3 fold over landrace varieties ■ Projects such as TL II have aggressively supported variety development, release and dissemination through integrated seed systems
■ Integration of the formal and informal seed production and distribution system has enhanced availability
■ With the uptake of these varieties and associated production packages, the national productivity has been on steady increase.

Conclusions ■ Ethiopian chickpea breeding program has enormously benefited from international collaborative research.
■ The most notable example was the response to wilt/root rot shown by Arerti (FLIP 98-84C) and Shasho (ICCV 93512) varieties.
■ AB resistant varieties such as Habru (FLIP 88-42C) were a solution to fungal disease problems.
■ Increasing genomic resources together with capacity building and support of projects such as TL III will revolutionize breeding with advanced breeding techniques.
■ Next steps will include exploitation of the existing indigenous genetic diversity and improvement of local landraces.
