OBJECTIVES/TARGETS
• Develop high yielding sunflower varieties (Hybrids & OPVs) resistant/tolerant to drought and major diseases with high oil content
• Develop appropriate agronomic practices for production of sunflower
• Develop integrated diseases management options for control of major diseases
• Disseminate appropriate sunflower technologies to uptake pathways and end users
Development of high yielding sunflower varieties resistant/tolerant to drought and major diseases
• Evaluated & identified 2 candidate Hybrids from EASL for release later this year
• 60 Lines were evaluated on-station
out of which 26, were identified as being superior
• The 26 lines are now being evaluated at 3 TVCs (Ngetta, Kumi & Kuju)
• 75 Crosses were made and are being evaluated
Development of high yielding sunflower varieties resistant/tolerant to drought
and major diseases
• 43 restorer lines were developed from imported hybrids
• Acquired 7 inbred lines with high oleic from germany
• Acquired 5 inbred lines with resistance to scretonia from germany
Development of appropriate agronomic practices for production of sunflower
• Tested two foliar fertilizers (Megacol, Push & New Suryamin)
• Inter-cropping regimes on-station ie Sunflower vs pigeon peas, cowpeas, green grams, beans, groundnuts, soybeans and cotton were conducted
• Sunflower-bean intercrop in a ratio of 1:1 gives the best results
Development of integrated diseases management options for control of
major diseases
• Surveys to identify distribution of major diseases, in different agro-ecologies were conducted
• 108 diseased sunflower samples/materials collected for identification and characterisation
• 26 advanced lines were identified being resistant to majar diseases onstation & were recomended for multilocational trials
• Two parental lines (CMS 372 and CMS 433) & their maintainers (HA 372 and HA 433) were identified with moderate resistance to leafspot
Dissemination of appropriate sunflower technologies to uptake pathways
• Multiplied and distributed 1200Kg & 200Kg of Sesun2H & Sesen1H, respectively to;
Seed companies (Pearl, EASL), Farmer Grps (P’KWII, UOSPA &
Amuria Farmers grp Mukwano grp of Companies
• Sunflower production manuals to be launched
Dissemination of appropriate sunflower technologies to uptake pathways
• Capacity building: Farmer trainning &Student mentoring
• Publication (Anyanga & Biruma)
• Posters
Constraints/challenges• Transport
• Infrastructure; Greenhouses, Laboratory space & equipments are insuffient
• High labour costs
• Delayed relaese of funds
• Insuffience funds
• Storage facilities
Constraints/challenges• Bereaucracies involved in
procurement
• Access to new germplasm sources
• Weather uncertainities; Drought, High Rainfall
• Emerging pests and diseases
• Rapid loss of viability in storage
• Bird damage
• Irregular power
Strategies to overcome the challenges
• Alternative sources of funding
• Networking
• Capacity building
• Lobbying
• Generate own germplasma
Development of high yielding sunflower varieties
resistant/tolerant to drought and major diseases
• Multi-location adaptation trials at 3 sites
• Multiplication of parental lines for hybrid sunflower seed
• Maintenance breeding
• On-farm evaluation of atleast 15 lines
Development of high yielding sunflower varieties
resistant/tolerant to drought and major diseases
• Widen germplasm base through collection (local and introductions)
• Continue with hybridization
• Oil content analysis
• Evaluation of the new introductions
Develop appropriate agronomic practices for production of sunflower
• Evaluation inter-cropping trial on-station and at various locations including farmers’ fields
• Determining the effects of sunflower on soil nutrient status
• Testing the effect of foliar and seed dressed fertilizers on sunflower yields
Integrated diseases management options for control of major diseases
• Screening for resistance (Advanced and introductions)
• Characterisation (physical & molecular) of the different pathogens
• Evaluate efficacy of different fungicides & botanicals
• Evaluate cropping systems in disease management
