Presentation Notes

Crossing within market classes: When both darker and lighter colors occur the paler is always genetically related to the darker color by a difference in a single enzyme. Some contrasting phenotypes are very close genetically eg, red and yellow seed color eg, small black and small red types, in adaptation in these cases the desired phenotype will segregate relatively easily

Presentation Notes

---Much has been said recently about the Product Pipeline (or Breeding Pipeline) and the stages (the Stage Gate System) that must be followed to create a new variety. But very little attention has been dedicated to the other two levels. ---As far as I know, no one has publicly suggested a scheme for Stage Gates for Trait Discovery. However, we have experienced some questioning about whether activity at this level is really integrated with breeding, and I suspect that this sort of skepticism may increase. We would be wise to organize our arguments and our presentation to show that we are orderly in our conceptualization, and that we clearly justify our efforts in these efforts. ----I am suggesting the scheme above as a series of Stage Gate steps in Trait Discovery, for our discussion. ----By any standard, these efforts need to be justified by a process of Trait Prioritization (e.g., future quantitative predictions of high temperature effects; damage by insects; demand for industrially processed beans; etc.)

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)

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

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
