“…CIAT and partners have contributed proactively to developing reliable and affordable phenotyping protocols to overcome bottlenecks in the breeding process. The use of near-infrared spectroscopy (NIRs) on fresh root samples greatly facilitated quantification of carotenoids contents (Sánchez et al 2014 ; Belalcazar et al 2016 ; Alamu et al 2021 ). It is now widely used in different biofortification projects.…”

“…The project RTBfoods: Breeding Roots, Tubers and Banana products for end-user preferences ( https://rtbfoods.cirad.fr ) is an ambitious initiative to elucidate basic information regarding root quality traits. Several research articles regarding root quality traits and post-harvest processing have recently been published (Alamu et al 2021 ; Bechoff et al 2018 ; Dufour et al 2021 ; Escobar et al 2021 ; Goddard et al 2015 ; Iragaba et al 2021 ; Luna et al 2021 ; Ndjouenkeu et al 2021 ; Teeken et al 2018 , 2021 ; Thiele et al 2021 ; Tran et al 2021 ). The availability of this critical knowledge and reliable high-throughput phenotyping protocols will improve the efficiency of breeding for root quality traits.…”

This paper reviews and analyzes key features from cassava breeding at the International Center for Tropical Agriculture (CIAT) over 50 years and draws lessons for public breeding efforts broadly. The breeding team, jointly with national program partners and the private processing sector, defined breeding objectives and guiding business plans. These have evolved through the decades and currently focus on four global product profiles. The recurrent selection method also evolved and included innovations such as estimation of phenotypic breeding values, increasing the number of locations in the first stage of agronomic evaluations, gradual reduction of the duration of breeding cycles (including rapid cycling for high-heritability traits), the development of protocols for the induction of flowering, and the introduction of genome-wide predictions. The impact of cassava breeding depends significantly on the type of target markets. When roots are used for large processing facilities for starch, animal feeding or ethanol production (such as in SE Asia), the adoption of improved varieties is nearly universal and productivity at the regional scale increases significantly. When markets and relevant infrastructure are weak or considerable proportion of the production goes for local artisanal processing and on-farm consumption, the impact has been lower. The potential of novel breeding tools needs to be properly assessed for the most effective allocation of resources. Finally, a brief summary of challenges and opportunities for the future of cassava breeding is presented. The paper describes multiple ways that public and private sector breeding programs can learn from each other to optimize success.

“…Near Infrared Spectroscopy (NIRS) offers possibilities to link root and food characteristics (Alamu et al, 2021). This requires following rigorous SOPs for NIRS scans on fresh roots from breeding trials, on the intermediate food products (if applicable) as well as on the final food products as prepared in food science labs following processing and preparation steps that have been externally validated by participatory processing of contrasting clones (new clones and processor preferred clones) in the working environment of the users (village cottage processing, or larger scale using mechanized processing depending on the product profile).…”

Towards Responsible Plant Data Linkage: Data Challenges for Agricultural Research and Development

Quality phenotype and genotype data are important for the success of a breeding program. Like most programs, African breeding programs generate large multi-disciplinary phenotypic and genotypic datasets from several locations, that must be carefully managed through the use of an appropriate database management system (DBMS) in order to generate reliable and accurate information for breeding-decisions. A DBMS is essential in data collection, storage, retrieval, validation, curation and analysis in plant breeding programs to enhance the ultimate goal of increasing genetic gain. The International Institute of Tropical Agriculture (IITA), working on the roots, tubers and banana (RTB) crops like cassava, yam, banana and plantain has deployed a FAIR-compliant (Findable, Accessible, Interoperable, Reusable) database; BREEDBASE. The functionalities of this database in data management and analysis have been instrumental in achieving breeding goals. Standard Operating Procedures (SOP) for each breeding process have been developed to allow a cognitive walkthrough for users. This has further helped to increase the usage and enhance the acceptability of the system. The wide acceptability gained among breeders in global cassava research programs has resulted in improvements in the precision and quality of genotype and phenotype data, and subsequent improvement in achievement of breeding program goals. Several innovative gender responsive approaches and initiatives have identified users and their preferences which have informed improved customer and product profiles. A remaining bottleneck is the effective linking of data on preferences and social information of crop users with technical breeding data to make this process more effective.

“…Papers address key problems in the breeding of RTB crops in SSA: inadequate understanding of requirements for different end uses, missing information on the physicochemical factors determining these requirements and absence of high‐throughput screening protocols. The review papers provide a broad overview of RTB production and use trends (Scott, 2021), describe case studies of varietal change (replacing old varieties with new ones) (Thiele et al ., 2021), summarise analytical methods for rapid quality assessment of yam and cassava using near‐infrared spectroscopy (Alamu et al ., 2021), describe gari end‐user preferences (Awoyale et al ., 2021) and review the literature to develop a product profile for fried sweet potato in West Africa (Carey et al ., 2021).…”

Summary “Consumers have their say: assessing preferred quality traits of roots, tubers and cooking bananas, and implications for breeding” special issue, brings together new knowledge about quality traits required for roots, tubers and bananas (RTB) varieties to successfully meet diverse user preferences and expectations, along the variety development and RTB value chains (production, processing, marketing, food preparation, consumption). Key RTB crops in sub‐Saharan Africa are cassava, yams, sweetpotatoes, potatoes and bananas/plantains. They are mainly consumed directly as boiled pieces or pounded in the form of smooth, not sticky, and stretchable dough. They are also stewed, steamed or fried. Cassava, the most widely grown RTB, is generally boiled, stewed or steamed in Eastern and Southern Africa, and in West and Central Africa is usually processed directly into derivative products, e.g. whole root fermentation through retting or heap fermentation; fermentation/dewatering of the mash. Biophysical and social knowledge presented in this issue help elaborate goals for both the processing unit operations (food scientist control) and variety traits (breeder control).
