Faba bean breeding for waterlogged vertisols of Ethiopia by Gemechu Keneni. Download PDF EPUB FB2
Soil acidity and waterlogging are among the common problems that limit the production of faba bean in Ethiopia (Keneni, Assefa, & Prabu, ). The variety ‘Walki’ was developed for waterlogged and vertisols areas and is gaining popularity in the central highlands of Ethiopia Cited by: 7.
About 29 improved faba bean varieties have been developed and released for different recommended domains, including the mid- and high-altitude agro-ecologies and Vertisols (waterlogged areas) up until Of faba bean growers, 19 percent are full adopters (all plots use improved varieties), percent are partial adopters (one or more plots.

Waterlogging is a major constraint of faba bean (Vicia faba L.) production in the highland vertisols of Ethiopia. Genotypes are currently evaluated under both the drained conditions of Broad Bed.
Faba bean (vicia faba L.) is one of the major pulse crops grown in the highlands ( – m asl) of Ethiopia (Temesgen and Aemiro, ). Faba bean is a valuable protein-rich leguminous crop cultivated and consumed as human food in the specified areas.
In addition, its straw is used as animal : Birhanu Amare Gidey. In Ethiopia, faba bean is the crop that has the highest absolute production, and the largest area cultivated. Ethiopia is also the second largest producer of faba bean in the world after China (Ronner, E.
and Giller, K.E.,). Faba bean is the most important pulse crop in terms of area coverage and total annual production in. High moisture level limits faba bean (Vicia faba L.) production in Vertisols, as the crop is sensitive to waterlogged conditions. In the central highlands of Ethi opia farmers t raditionally.
Faba bean breeding in Ethiopia was started in the ’s with the prime objectives of improving grain yield, seed size and resistance to important diseases, particularly chocolate spot (Botrytis fabae) (Keneni et al., ). ecologies and Vertisols (waterlogged areas) up until Of faba bean growers, 19 percent are full adopters (all plots use improved varieties), percent are partial adopters (one or more plots use improved varieties), and the remaining percent are non-adopters (all faba bean plots use local varieties).
However, only. In Ethiopia, Vertisols account for million hectares, of which about million ha found in the highlands and are generally waterlogged due to abundant rainfall during the growing period.

Field survey was conducted in south eastern Ethiopia to determine the disease intensity of chocolate spot and rust and to investigate the association of disease intensity (incidence and severity) with environmental factors and crop cultural practices.

Faba bean (Vicia faba L.) also referred to as broad bean, horse bean and sometimes field bean, occupies nearly million ha faba bean production is concentrated in nine major agro-ecological regions: the Mediterranean basin, the Nile valley, Ethiopia, central Asia, east Asia, Oceania, Latin America, northern Europe, and North America.

Proceedings of the 10th Annual Conference of the Crop Sci. Society of Ethiopia, JuneEARO, Addis Ababa, Ethiopia, Faba bean (Vicia faba L.) is one of the earliest domesticated food legumes of the world.
This study was designed to reveal the genetic diversity existing among 32 Ethiopian faba bean varieties grown at three locations (Sinana, Agarfa and Selka) using 23 phenotypic traits and 11 inter simple sequence repeat (ISSR) primers.
The combined analysis of variance across the three locations. Despite the difficulties, plant breeders accepted improved response to stresses as achievable plant breeding goals. For instance, different varieties of barley and linseed were developed for frost-prone highlands of Ethiopia, while that of tee, noug and faba bean were bred for waterlogged black soils (vertisols).
Improved Adaptation. Abstract. Faba bean (Vicia faba L.) is an important food legume crop in Ethiopia, and its production and productivity are decreased by biotic and abiotic the biotic stresses, chocolate spot disease is the major and the most destructive disease in faba bean-growing areas.
Experiences from breeding faba bean for waterlogged vertisols, where black root rot is a severe associated problem, showed that indirect selection under Broad Bed and Furrow (drained environment) may be useful to identify better genotypes for flatbed conditions (waterlogged environment), but the.
Faba bean (Vicia faba L.) is a major food and feed legume, because of the high nutritional value of its seeds, which are rich in protein and starch. Seeds are consumed dry, fresh, frozen or canned.
The main faba bean producer countries are China, some in Europe, Ethiopia, Egypt and Australia. 1. Introduction. Faba bean (Vicia faba L.) is a major food and feed legume crop worldwide, and the main faba bean-producing countries are China, Europe, Ethiopia, Egypt and Australia (Duc et al., ; Jensen et al., ).Faba bean is produced in diverse agro-ecologies and farming systems in Ethiopia (Asfaw et al., ; CSA, ; Mussa et al., ), and covered more.
Introduction. Faba bean (Vicia faba L.) is one of the most important legume crops used as food for human consumption in developing countries and as animal feed in advanced is the fourth important pulse crop in the world after dry bean, dry peas, and chickpeas (Kumari and Van Leur ).Its value as a food and feed crop lies in its high lysine‐rich protein, vitamins, minerals.
poor soil fertility and waterlogged conditions, and in areas receiving only – mm of annual rainfall. In Ethiopia, grass pea is commonly cultivated on heavy clay soils (mostly vertisols). Planting is done in late August to early September, and as such, the crop is supposed to take advantage of the residual soil moisture.
It is an eﬃcient. Faba bean is an important grain legume grown on vertisols of central high lands in Ethiopia, and is constrained by low yielding varieties, soil acidity, besides scanty information on optimum plant density and phosphorus nutrition. Several varieties with a high-level resistance to chocolate spot, derived directly or indirectly from the ICARDA breeding program, were released by EIAR.
In addition, because of the high prices of faba bean in Ethiopia, farmers are expanding faba bean production on vertisols that are confronted with root rots favoured by stagnant water. 12 Faba bean status and prospects in Tunisia (M.

Kimber and J. van Leur) 18 Breeding priorities for improved nutritional value of Vicia faba. Chickpea (Cicer arietinum L.) is an economically and ecologically important food legume ia has a large collection of chickpea germplasm accessions; but, it has not been extensively characterized for desirable sources of agronomic and symbiotic significance for use in breeding programs.
Faba bean (Vicia faba L.), also referred to as broad bean, ﬁeld bean, tick bean, windsor bean and horse bean, is one of the oldest crops grown by humans and is a valu-able protein-rich food and animal feed (Link et al., ; Duc, ; Zong et al., ).
Large-seeded faba bean grain is usually used as food, while medium-sized grain. Plant breeding is one way to confront the challenge of bridging the widening gap between the demand and supply of food.
Despite the importance, however, plant breeding has its own negative side effects. The replacement of landraces with a few genetically uniform varieties depletes genetic diversity and provides ideal conditions for diseases and insect pests that called genetic vulnerability. The well-established relative deficiency of faba bean in essential sulfur-containing amino acids, cysteine and methionine, can of course be balanced in food, and feed processing, but amelioration of the balance of essential amino acids would be a valuable breeding target which has not yet been addressed (Multari et al., ).
Finally, in order.Also, Ethiopian Vertisols occur on a wide range of slope up to 15% (Jutzi et al., ) though the majority occurs on slopes less than 5%, against the claims of Mohr et al. () and Debele (At present faba bean is the third most important cool-season food legume in the world (Torres et al.,).It is grown as field crops throughout the highlands and is most common in woina dega between the altitudes m.a.s.l and m.a.s.l (Asfaw Telaye,).
In Ethiopia, faba bean is the leading protein source for.
