In each breeding station, we maintain a set of germplasms relevant for both parental improvement and product
development. This consists of wild diploids, improved diploids and tetraploids and landraces sourced from the international transit centre (ITC), national partners and other international Musa breeding programs. Routine cross-pollinations are carried out to develop new varieties and improve parental lines. In parallel, we genotype the germplasm and breeding populations for QC/QA in the breeding pipeline and to generate SNP markers that are used in genome-wide association studies and QTL mapping. Markers tightly linked to traits are converted into KASP assays for routine marker assisted selection. We have also developed a medium density marker panel and pangenome to facilitate diversity studies, gene discovery for gene editing and genomic selection.
We conduct both field (on station, multi-location and on-farm) and controlled conditions (screen house and glass house) phenotyping using well
established and approved SOPs. We measure traits such as yield, agronomic performance, pest and disease resistance and quality in both the germplasm and hybrids to select superior parents and new varieties. Image based phenotyping is under development for all traits.
We operate an end-to-end digitalized breeding program where data is digitally captured using FieldBook and BTracT
and stored in MusaBase, enabling easy access, retrieval and traceability using a barcoding system. We have transferred this to 3 NARS and plan to transfer to all NARS partners of the banana breeding network for use in multi-location and on-farm verification trials. All our trials are established using appropriate statistical designs through consultation with biometrics and B4T quantitative genetics team and the data generated is analyzed in approved analytic pipelines in Bioflow to enable genetic gain estimation and other key results needed for breeding decision.
In collaboration with NARES partners and other stakeholders, the program conducts annual product advancement meeting
(PAM) to select elite parents and potential breakthrough products for the next stage of evaluation. On-farm verification trials and national performance trials are conducted in accordance with harmonized protocols and national guidelines towards registration and release.
The program has well-established tissue culture laboratories with technical staff in all breeding stations to multiply breeder’s seed to
facilitate dissemination and delivery of improved varieties. This is done in collaboration with IITA genetic resource centre and germplasm health unit for global distribution. The program for seed systems innovation for vegetatively propagated crops in Africa (PROSSIVA) helps to coordinate private tissue culture laboratories and community-based seed entrepreneurs (CSE) that have been trained in macro-propagation technologies to ensure delivery of clean planting materials to the farmers. Social Economists are engaged to assess the adoption rate and socio-economic impact resulting from the new varieties.
The key activities of the IITASBP have been:
The program in collaboration with ABI-Transform and currently Breeding for Tomorrow AoW ENABLE has conducted several country-specific product design team meeting with stakeholders across the banana and plantain value chain and defined market segments (MS), target population of environments (TPE) and target product profile (TPP) to align breeding objectives with market demands. The TPP define value propositions such as high yield and low risk and loss to biotic stresses.
The program also conducts trait discovery and deployment under pre-breeding by conducting GWAS analysis, QTL mapping, diversity analysis, karyotyping, development of QA/QC markers, and low-density markers such as KASP for marker assisted selection (MAS), leveraging available genomics tools and genotyping platforms.
The main activities of the program include cross pollinations to generate new hybrids that are evaluated for yield, agronomic performance, pest and disease resistance and quality, selected and advanced through different stages of the pipeline including early evaluation trial (EET), preliminary yield trial (PYT), multi-locational evaluation trials (MET), on-farm verification trials (OFVT) and national performance trials (NPT). All these operations are digitalized using tools like FieldBook and BTracT, and the data made available to the Musa community through MusaBase.
The program is also involved in some fundamental research such as floral biology to enhance seed production and hybrid recovery, through projects such as RTB pollen storage to enhance breeding efficiency, 2n gamete induction to facilitate diploid by diploid breeding to generate sterile triploid varieties, RTBFoodomics to understand metabolites responsible for food quality. In all these research activities, capacity building is embedded giving opportunities for master’s and PhD students.
The program is also exploring the use of digital phenotyping and use of AI models to improve data quality and phenotyping efficiency to enhance the precision of breeding decisions. Digital phenotyping has been developed to screen for weevil resistance using Image J and Machine Learning models. This is being extended to Fusarium (Foc R1) and nematode necrosis screening. We are also exploring estimation of bunch weight using images and ML-models.
In Kagera, the 48% adoption rate of FHIA hybrids has boosted production of bananas by 15%, resulting in US$ 7 million per annum for the region. It is important to note that it took nearly 15 years to achieve this.
The recently released NARITA 17/NAROBAN 6 in Uganda has a yield advantage of 243% when compared to local landrace check Mbwazirume. It is resistant to Black Sigatoka, Foc R1, TR4, and
nematodes but also tolerant to weevils and has good table quality attributes surpassing earlier releases.
The released improved plantain variety yields up to 30 t/ha in Côte d’Ivoire. It is resistant to Black Sigatoka and tolerant to nematodes with a yield advantage of 64% over local landrace Agbagba.
