Twenty-three varieties further evaluated in Nobewam dry season. Data being processed
Makassane
Seeds of ALL lowland varieties given to GAFCO, Sogakope for field testing (after approval from PASS coordinator) Vish, GAFCO rice breeder
Seeds of all 30 lowland varieties further evaluated by Wilson Dogbe of SARI at Libi. Terminal drought
Seeds of all 30 lowland varieties also evaluated by George Acheampong at Hohoe under Rice Sector Support Project Data to be incorporated for multi-locational analyses
Selections are being made from over 3,000 F1, F2 and BC1F1 populations in Nobewam
2. Africa Rice Breeder’s Task Force Regional Trial – 100 varieties, 3 reps Data being processed
UPLAND 116 upland rice varieties from CRI and AfricaRice evaluated Nobewam rainy season. Data being processed
11 upland rice varieties also evaluated in AYT in Nobewam. Data being processed
11 upland rice varieties evaluated in AYT in Fumesua. Terminal drought
Upland Advanced Yield Trial – Nobewam dry season 22 varieties. To be harvested
9 lowland and 10 upland varieties evaluated for grain quality Milling Potential Scores (MPS), Milling Yields and Milling Yield Classification Physico-Chemical Properties: Grain dimensions, size and shape classification, chalkiness, grain hardness & gelatinisation temperature Cooking Properties: Cooking time, swelling and water absorption ratios Varieties have low gel temp and acceptable hardness, but some are chalky Grain quality tests to be repeated 2012 GRAIN QUALITY – courtesy John Manful, AfricaRice
3. Public-Private Partnership for Improving Rice Productivity in Nitrogen-Deficient and Saline Environments of Sub-Saharan Africa (NEWEST RICE PROJECT) Aim: Transform Nerica4 for Nitrogen use efficiency, water use efficiency and salt tolerance Transformed Nerica 4 for NUE delivered to CIAT, Colombia, by Arcadia Biosciences, US Approval given for importation of same into Uganda CRI’s application being reviewed by IBC before submission to NBC
Maize variety Abontem on in Nobewam. To deplete soil Nitrogen.

THANK YOU
LAYT-1 at maturity, Aframso. Floods prevented temporary access to field. Note late maturity of traditional Mr Moore variety
