BRÍO – rapid and market-focussed crop breeding for sustainable and superior genetic gain What is BRÍO?
BRIO breeding
B BLUP analysis, exploiting pedigree and genomic relationships and correlated traits across cycles
R Rapid cycles of recurrent selection on inbred or non-inbred progeny, or both
I Index selection based on economic value of traits
O Optimised mating designs for sustainable and superior genetic gain
BRÍO is being developed in collaboration between African and Australian crop breeders in ACIAR project CROP/2018/132
Traditional crop breeding
Phenotypic analysis based on recent trial data; disconnected across years, cycles and traits
Associative mating designs increase genetic drift and risk of premature yield plateau
Slow cycles (6 to 10 years) with selection on inbred progeny
Truncation selection and independent culling reduce long-term genetic gain
con brio: with vigour, vitality, energy, strength.
Optim
ized Breeding methods
Multi-actors approach for enhanced seed production and access
Multi-stakeholders platforms for:• Annual planning and reviews (MLE)• Identification of variety demand • Linking value chain actors• Forums for training and skills
enhancement• Enhancing efficiency and
effectiveness in technologies’ promotion
Basic seed (NARS & Accredited seed enterprises)
Certified seed (large and small packs) using market and non market channels
Certified/Quality Declared Seed (Farmer organizations & Individual entrepreneurs)
Breeders seed (NARS & Accredited seed enterprises
Mechanization: time/labour saving technologies• reduce drudgery, increase production/quality of post-harvest products

Bean yield obtained by farmers who did not use climate information (kg ha-1)
(a) Generally, farmers who used climate information got higherbean yield than those who did not (Fig. a). Data were collected in 8 districts representing 4 agro-ecological zones in Rwanda (Fig. c)
In more 95% cases, farmers who used climate information in bean production had additional bean yield ranging between 0.1 and 1.5 t/ha compared to those who did not use climate information in bean production (Fig. b)
(C)
Location of 120 farmers who participated in bean production study on the impact of using climate information for increased
resilience to climate related risks in Rwanda for two seasons in March to May 2018 and
2019
Deployment and impact of climate information services on bean productivity e.g. Rwanda
Initiative being expanded in 10 countries
Multiple crop threshing services
Benefits Several business in the manufacturing (USD800 per machine) Employment and income to the owner (youth): USD14 /hour Quality products 99% (minim breakages etc.) Reduce women and children drudgery Cost of threshing beans (50% reduction)

Catalyzing small and medium youth and women enterprises while delivery nutritious products
(1) Rural based industrialization- processing and valueaddition to develop value added products bean flours,precooked beans, etc
Inclusive economic growth by providing reliable marketopportunities to farmers women empowerment,employment all along the value chain, especially foryouth
(2) Nutritional benefits: especially for women and children(e.g Iron and Zinc); health benefits by preventing non-communicable diseases (obesity),
(3) Contribute to sustainable school feeding programme
