  1. Development of high yielding sunflower varieties with desirable market attributes, and appropriate crop management options 29th August 2012 Annual Review Presenter: Moses Biruma

  2. Project staff 4 Scientists • Anyanga Walter Breeder • Pius Elobu Agronomists • Gayi Denis Entomologist • Moses Biruma Pathologist/Molecular Biologists 2 Technicians • James Oumo & Betty Alepo 1 Secretary and 4 Field Assistants Numerous other support staff

  3. 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

  4. Achivements/progress

  5. 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

  6. 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

  7. 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

  8. 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

  9. 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

  10. 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

  11. Dissemination of appropriate sunflower technologies to uptake pathways • Capacity building: Farmer trainning &Student mentoring • Publication (Anyanga & Biruma) • Posters

  12. Constraints/challenges • Transport • Infrastructure; Greenhouses, Laboratory space & equipments are insuffient • High labour costs • Delayed relaese of funds • Insuffience funds • Storage facilities

  13. 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

  14. Strategies to overcome the challenges • Alternative sources of funding • Networking • Capacity building • Lobbying • Generate own germplasma

  15. Research activities in progress/Planned activities

  16. 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

  17. 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

  18. 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

  19. 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
