Wheat varieties development strategies in Rwanda

  1. 1. Wheat Variety Development Strategies in Rwanda 1 I. Habarurema, 1A. Musabyisoni, 1 A. Hategekimana, 1 G. Gumisiriza, 1 M. A. Ingabire, 1 M. Uwamahoro, 1 A. Kayumba and 1 G. Nshimyimana 1 Rwanda Agriculture Board (RAB), Kigali, Rwanda Northern Agriculture Zone Division (NAZD), P.O Box 73, Musanze, RwandaBackgroundWheat (Triticum æstivum L.) is currently grown in three agro-ecological zones ofRwanda, namely Congo-Nile Crest, Volcanic soils and Buberuka highlands, circled red,blue and purple respectively (Fig.1) at altitudes above 1,900 masl. An estimated 40,000ha have been planted to wheat in Rwanda during the current 2012B season. With grainyield ranging from 3 to 3.5 tons/ha, the total wheat production is expected to shift from72,250 tons obtained in season 2011B to 124,500 tons in 2012B. The major constraintsto wheat production in Rwanda include lack of appropriate varieties, pests and diseases,low soil fertility and limited agricultural land due to high population pressure. Therefore, abreeding program to improve productivity is regarded as a sustainable approach toovercome these constraints.Mission Fig. 1. Wheat growing areas of RwandaTo develop and disseminate holistic technology packages to improve breadwheat productivity and income of small-holder farm households in Rwanda. Introductions (CIMMYT, Regional & others)Objectives Screening nurseries• Evaluate and select promising wheat lines from CIMMYT & national wheat Preliminary yield trials programs introductions on-station and in farmers’ fields under Rwandan conditions; Advanced yield trials & gluten testing• Release and promote the best lines with good milling and baking qualities for commercial production in Rwanda; Comparative yield trials & characterization• Promote production and dissemination of improved wheat seed to farmers. Multilocation & farmer participatory evaluationCurrent activities Variety release1. Participatory variety selection: Wheat breeding activities are mainly Fig.4 Participatory breeding scheme followed by Work done so far based on selection among introduced materials from CIMMYT-Mexico & RAB wheat program national wheat programs of Burundi, Kenya, Tanzania, Ethiopia, Sudan, 2. Release and promotion of superior genotypes Uganda and Australia. The germplasm from CIMMYT is in form of stabilized Demonstration plots for one promising line have lines from nurseries that include HRWYT, HRWSN, ASWSN, HTWYT, been established in farmers’fields in different AEZ IBWSN, SAWSN, ECAWIN and BWME2HR. for subsequent release by the end of the current About 330 genotypes have been evaluated at different stages for yield, pest season 2012 B. and disease tolerance and general adaptation at Rwerere, Kinigi and 3. Production and dissemination of improved Nyamagabe Research Stations under environmental conditions conducive seed for wheat production and pests and diseases development (Fig. 2). A Four varieties including EN161, KS Mwamba, participatory evaluation of 13 lines selected from on-station has been EN48 and Musama are currently under conducted in farmers fields of Musanze, Burera, Rulindo and Nyamagabe commercial seed production. Both basic and Districts during the seasons 2012 A and B (Fig. 3), to select superior line (s) foundation seeds have been produced on station for release to farmers. The selection scheme followed by RAB wheat for subsequent dissemination to seed growers for program is shown in Fig. 4. certified seed production. This activity is motivated by the Crop Intensification Program (CIP). Way forward Initiating a crossing program using existing materials to select higher yielding progeny resistant to rusts and other diseases; Using conventional and appropriate molecular techniques to assess milling and baking quality early in order to select and disseminate more competitive and profitable bread wheat varieties.
