Improving production potential of sorghum and finger millets through genetic improvement and participatory farmer research for development
- 1. Improving production potential of sorghum and finger millets through genetic improvement and participatory farmer research for development Biruma M., Dramadri I., Liri C., Mayada M. Beshir, Bombom A. and Okori P.
- 2. Why sorghum & finger millet • Widely cultivated throughout the East African region • Well adapted for dry and semi-arid tropical regions • Earmarked as critical crop investment vehicles that can help deliver the millennium development goals
- 3. • Major drawback to increased sorghum and millet production • Low competitiveness of both crops in terms of yield and market penetration due to limited value added products
- 4. Biotic and abiotic stresses further compromises the yield
- 5. • Exploiting genetic diversity through crop genetics provides one of the most effective ways to address both challenges • The goal of our work is to improve yield performance of both crops by: 1. Developing sorghum genotypes with multiple resistance (focus foliar diseases [Anthracnose & TLB], drought and striga 2. Development of niche specific sorghum varieties 3. Utilise wild finger millet relatives to improve cultivated finger millet
- 6. • Both field and green house experiments under controlled environments were used
- 7. Reaction of sorghum genotypes to Striga, foliar diseases and drought Head Striga wt 100gr. Height DTF GLA Vigour Ant.

- 8. • To promote variety adoption a participatory variety selection is being used
- 9. Development of niche specific sorghum varieties • Nutrient analysis of promising lines • Trials on poultry and piggery feed formulations
- 10. Overview of finger millet work: See poster for details • Focus drought, tillering ability, blast resistance and grain yield improvement • Crosses between the cultivated and wild relative (E. africana & E. kigeziensis)
- 11. • Crosses between cultivated finger millet and wild relatives(allotetraplo ids) of diverse origins are possible producing superior fertile hybrids. • Potential for tillering, earliness, drought and high grain yield improvement
- 12. • Reaction of F2 plants to drought stress
