1. RESEARCH FOR DEVELOPMENT IN-HOUSE REVIEW 2012 Stress Tolerant Rice for Africa and South Asia (PVS on Rice varieties tolerant to Fe Toxicity) E. Annan-Afful

2. It’s an on-going project Funded by AfricaRice (formerly WARDA) Collaborating Institutions CSIR-Soil Research Institute MoFA

3. Introduction STRESS- Fe Toxicity What is Fe toxicity? Fe toxicity is a widespread nutrient disorder that affects lowland rice growing areas, especially, in the humid tropical regions of Africa. Causes of Fe toxicity It is brought about by the excessive Fe absorption by the rice plant in the form of Fe 2+ rather than Fe 3+

4. Symptoms of Fe toxicity

5. Some effects on plants/yield It aggravates disease severity Average yield loss amounts to about 50% in affected areas (range 50-100%) In most affected areas, farmers sometimes abandon their land in search of new areas or change their cropping pattern eg. Oil palm

6. The Project-STRASA Goal: To reduce poverty and hunger and increase food and income security of farm families and rice consumers in South Asia and Sub-Saharan Africa through the development and dissemination of rice varieties tolerant to abiotic stresses. Objectives Develop and disseminate stress tolerant germplasm for Fe toxicity Promote seed exchange and varietal release through INGER and other mechanisms Up-scaling seed production and delivery of improved technologies

7. What has been done Yr 1: Seed garden establishment at the 3 selected hotspots (Adansi-Atwereboana in the Adansi North District, Agyareago in the Asante-Akim District and Assin Akonfudi, Assin North District) Consisted of 80 lines each at the 3 sites PVS was done and 10 out of the 80 were selected Yr 2: Seeds of the 10 lines selected were multiplied in the dry season for Mother and Baby trial in 2011 Yr 3: Evaluation of the 10 lines in 2011

8. Activities carried out in 2011 Establishment of trials at the three sites (Assin- Akonfudi, Adansi-Atwereboana, Nobewam) 12 lines, including 2 local varieties were evaluated at the 3 sites Farmers were invited to the field to make their selection
