Variety Release
6. Current adoption of new banana varieties slow and
lower than expected
Breeders often give priority to “key traits” (Brown et al,
2017) and to lesser extent & later in breeding cycle tastes
that markets demand
Approach may fail to consider potentially important traits
and other factors (earlier in breeding pipeline) for which
economic value maybe more difficult to assess →
consumer attributes
Adoption of ‘new’ varieties
7. Project activities (Work package 4)
1. Evaluation of promising EAHB hybrids (NARITAs) developed by
NARO and IITA in UG & TZ -‘Breeding Better Bananas’ project
Multi-location participatory varietal selection (PVS)
Assess extent to which gender-differentiated preferences have been
documented in Sub-Saharan Africa (systemic lit review)
Characterize target population environments (TPEs) from a gender
perspective (baseline survey)
Assess suitability of hybrids to local farming conditions in TPEs (on
station and on farm trials, crowdsourcing )
Evaluate key criteria used by male & female farmers to adopt/reject
‘new’ cultivars; assess acceptability (sensory eval, preference ranking)
8. Project activities cont.… (RTBfoods)
2. Understanding drivers of trait preferences and development of
multi-user banana product profiles - ‘RTBfoods’ – new project
Develop gendered product profiles for cooking bananas - set of
quality criteria that meet consumer demand to inform physio-
chemical characterization and demand-led breeding programs
Ultimate goal: Develop and disseminate varieties that
meet user preferred quality traits to increase adoption
and improve food security and welfare of men, women
as well as households in target communities
9. Using the “Decision checklist
G.Smith/CIAT
Decision Checklist (Green = required
info has/will be collected)
Examples of decision(s) made/to be
made
1)Gender included in social targeting:
Have market segments been defined and
then prioritized to be targeted, with a
gender dimension?
2)Sampling: Are the data used for
targeting and for the resultant customer
profiles representative of the gender-
differentiated population(s) that the
breeding program expects will adopt its
actual or future breeding products?
3)Does the customer profile for each
social segment the program decided to
target have a gender dimension?
Baseline study in 2 target regions where
banana is grown: high banana producing
region (i.e. Western UG) and one with
high demand but prod has reduced
(Central UG)
Sampling strategy – purposive at
regional & district level; random at
village and ensured both men and
women were included
Segments to target – male and female
farmers (growers) in banana growing
communities
10. Using the “Decision checklist
G.Smith/CIAT
Decision Checklist (Green = req info
has/will be collected, red =
no/limited info)
Examples of decision(s) made/to be made
4)Has the demand for desired traits
been determined representatively –
for each customer profile, taking
gender into account? What is the
most important demand of the most
important customer?
5)Have alternative outcomes (and
impacts) for breeding been evaluated
considering the expected economic,
environmental, food security and
nutritional gains for the targeted
beneficiaries with explicit
consideration of changes in gender
equity?
Methods to better understand gendered trait
preferences, particularly ‘quality,
consumption and processing’ traits as they
seem critical for adoption
Analytical methods to provide measurable &
quantifiable traits packages
Questioning what ‘yield’ means to diff
segments: harvesting ‘reasonably’ sized
bunches throughout yr. vs bumper harvests at
peak times for commercial purposes
Need to assess breeding feasibility for some
traits?
11. Using the “Decision checklist
G.Smith/CIAT
Decision Checklist Examples of decision(s) made/to be
made
6)Which changes for which traits
are most desirable, which
changes are necessary for a
product to be of value for the
targeted customers? Have traits
been valued with a gender
dimension?
7)Have feasible trait packages
been defined considering
potential impact on gender
equality for men and women in
different customer segments?
Methodologies to collect, analyze
and collate ALL req info to develop
the ‘product profile’
→ (which traits to maintain,
maximise, minimise, reach threshold)
e.g. soft texture, yellow pulp colour
in Uganda for matooke (‘food’),
maturity time etc.
12. Decision Checklist Examples of decision(s) made/to be
made
8. Has new variation been created
or identified considering gender
differentiated trait preferences
and priorities?
9. Are gender-differentiated
preferences included in
evaluation criteria (whether by
breeders’ or participatory
evaluations)?
Evaluation of varieties by farmers on station
Methodologies for sensory evaluations &
preference ranking that will capture male &
female user’s criteria
Decide best methodology and how to
streamline process and assess cost
effectiveness
10)Are gender-responsive strategies
for seed production and
distribution in use?
Need to collect more data to support
baseline data and literature on prod.
constraints & gender inequalities in target
regions (limited info for some regions)
Using the “Decision checklist
13. Addressing Decision Points 1 and 2 –
‘who to target…? , who are the customers…?
Research progress
Baseline study in 2015/16 - 2 target regions in Uganda and 4 in Tanzania
Sex disaggregated - intra household survey & FGDs to characterize target
population environments (TPEs) & understand end users’ needs and preferences.
~1000 hhlds, 1325 respondents (52.6% women) & 95 FGDs (44 ♂only, 46 ♀only,
5 mixed)
What next?
Assess poverty levels, food security status, willingness to adopt , seed systems by
gender etc.
Identify ‘products’ (hybrids) to satisfy different regions in both UG & TZ
Emerging issues e.g. importance of cooking vs juice types and possibility of other
processing options ?
14. Addressing Decision Point 3 – ‘demand for
desired traits, taking gender into account for customer profile, impact on
breeding…’
Research progress
Systematic literature review, submitted to Agric and Food Security
Few studies documenting gender disaggregated trait preferences – only 4 from 44
Farmers prefer traditional cultivars with superior consumption attributes, even if
prone to pests & diseases
Women & men value similar traits related to cooking quality, prod. constraints (e.g.
resistance to pests), income enhancement, cultural use; women stated traits related to
prod. (high suckering ability, early maturity)
Long list of traits- not detailed, not ranked → challenging for breeders to prioritize
Baseline data analysis
Prelim results: potential complexity for breeding → large no. of factors (products,
traits before & after processing, location, varieties)- need biochemical quantification
Consumption & processing attributes critical, but poorly understood in terms of:
assessment (measurement), inheritance & their physicochemical nature (NARL,
Uganda -analysing NARITAs)
15. Addressing Decision Point 3 – ‘demand for
desired traits, taking gender into account for customer profile, impact on
breeding…’
What next?
Assess gender differentiated trait preferences,
reasons for preferences, impact of different
attributes on adoption
Further analysis on relative importance of
consumption & processing attributes for
adoption in the diff agro- ecological zones:
are there gender differences, who has the
knowledge/expertise → multilocation
sensory eval.
Evaluations with other value chain actors in
the different agro-ecologies and social
contexts
16. Protocol and tool development
Impromptu meetings - lessons learnt from both breeding and
social science side
Field visits together e.g. to determine which of the hybrids to take
on farm, Robooni showed how farmers/other actors check
characteristics that determine the potential end use of the banana
Participated together in the Gender & Breeding Post-Doctoral
Fellow (PDF) Study Design Workshop
Report and paper writing (co-authorship) – submitted literature
review
Interdisciplinary dialogue
17. Final remarks
Collaboration between breeders, social
scientists, food scientists etc. extremely
important
Need to probe further and use methodologies
that can tap into tacit knowledge
Use methodologies that rank traits in order of
importance, instead of long lists of traits.
Breeders need measurable and quantifiable traits
Traits demanded by men and women may
converge in some instances hence gender
differences not always important
Should not just narrowly look at gender – go
beyond the binary sex disaggregation
yield gap is the difference between attainable and actual yields
“The primary objective of most banana breeding programs is the uniform production of large bunches that meet the regional qualitative and quantitative demands of growers. These demands include superior fruit quality, high suckering ability, short stature, and enhanced root systems that provide effective soil anchorage and efficient uptake of water and minerals. Other agronomic traits such as photosynthetic efficiency and rapid cycling are also important breeding objectives for increased yield. The relative importance of these objectives varies across geographic regions, among subgroups.” In recent years, the anticipated and realized threats of pests and diseases have resulted in increased emphasis placed on identifying and utilizing improved sources of host-plant
Resistance to pests and diseases, particularly in regard to the Sigatoka complex, multiple races of Fusarium wilt, bacterial wilt, bunchy top, nematodes, and weevils.

Physicochemical analyses - properties for the quality, high throughput phenotyping platform development, product testing and varietal evaluation
Highlighted in green in first column are the decision points being addressed by research.
In general will refer to background info for some of the questions
*Product profile of the product concept notion.
“…marketers will look into a product concept before marketing a product towards their customers. While the "product concept" is based upon the idea that customers prefer products that have the most quality, performance, and features, some customers prefer a product that is simpler and easier to use.”

Recap of decision checklist point 1 and 2
1) Gender included in social targeting: Have market segments been defined and then prioritized to be targeted, with a gender dimension?
2) Sampling: Are the data used for targeting and for the resultant customer profiles representative of the gender-differentiated population(s) that the breeding program expects will adopt its actual or future breeding products?
3) Does the customer profile for each social segment the program decided to target have a gender dimension?
Recap of decision checklist 3
4) Has the demand for desired traits been determined representatively – for each customer profile, taking gender into account? What is the most important demand of the most important customer?
5) Have alternative outcomes (and impacts) for breeding been evaluated considering the expected economic, environmental, food security and nutritional gains for the targeted beneficiaries with explicit consideration of changes in gender equity
- Farmers are producers, processors & consumers
Studies documenting end users’ preference in order of importance or highlight end users’ priority traits limited

Post docs w/shop objective – deepen shared understanding and jointly design a cross-CGIAR Research Program (CRP) study on gender and breeding that will enhance ability of CGIAR breeding programs to be more effectively end-user targeted and gender-responsive building on existing CGIAR Post-Doctoral Fellow projects
Methodologies- repertory grip, sensory profiling - aassessment of sensory attributes related to cooking and consumption not easy. Often the descriptors/traits and the data collected is vague and not detailed enough for use in breeding programs e.g. ‘nice taste’, ‘good texture’
