“…Breeding efforts for understudied crops greatly benefit from the exploration of global germplasm within local testing environments to assess available genotypic diversity (Wang et al., 2017). Such assessments of diversity in exotic and adapted materials is an effective method to identify suitable plant materials in breeding programs (Jackson et al., 2020), identify novel alleles (Gao et al., 2017), and evaluate genotype × environment interactions (Ayalew et al., 2019). Plant breeding requires a strong comprehension of available materials, knowledge of potential bottlenecks, and the development of effective breeding schemes.…”

Exploration of global faba bean germplasm for agronomic and nitrogen fixation traits

The growing regional and global interests in legume crops for cover cropping and sustainable agriculture has provided new opportunities for growers to incorporate faba bean (Vicia faba L.) into their production systems. Much of faba bean's potential, especially in the western United States, is rooted in its high N fixation potential compared with other cultivated legumes. However, faba bean production is currently hindered by existing markets, regional agronomic extension guides, and availability of regionally adapted cultivars. This experiment began the effort to bridge one of the three gaps by evaluating 63 regionally and globally derived plant materials for agronomic and N fixation traits in four environments in California's Central Valley. The experiment observed significant (P ≤ .05) genotype × environment interactions for all faba bean N and agronomic except % of N derived from the atmosphere, harvest index, and 100-seed weight. Further, we found opportunities to leverage global germplasm to increase or decrease the 100-seed weight and days to flowering in locally adapted plant materials. Finally, this experiment identified trait-trait-associations that provide both opportunities and challenges to improving screening efficiencies (e.g., link between N yield and 100-seed weight in Chico2019 [r = 0.57; P ≤ .001] and in Fresno2020 [r = 0.51; P ≤ .001]). This work sets a framework for regional faba bean cultivar development work in the western United States. INTRODUCTIONA deeply intertwined interest in sustainable food systems and compatible specialty markets continues to grow in the western United States which opens the door for the plant breeders to reassess the potentials of once orphaned food crops. Among crop species, legumes have great potential for sustainable agricultural systems due to their value for human consumption Abbreviations: %Ndfa, N derived from the atmosphere.This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.

“…Similar results were reported by Alc antar-Mej ıa et al ( 2012), who studied the altitudinal distribution of the genus Ipomoea in the state of Michoac an, Mexico, where they managed to collect accessions from sea level to 3,000 masl but found the greatest amount of materials in the 0-299 and 1,800-2,099 masl ranges. Sweet potato is a complex species due to the great genetic and morphological variation (Carranza 2007;Jackson et al 2020;Wadl et al 2018). It exhibits a wide natural distribution and adaptation to different environmental conditions.…”

Sweet potato is a valuable staple crop that guarantees food security to a large segment of the world population. The wide phenotypic and genetic variability of this species is an indication of its high adaptation capacity to diverse environmental conditions. In Colombia, it is a neglected and underutilized crop, mainly managed by traditional knowledge. The aim of this study was to recognize the contribution of in situ conservation and to characterize the habitats and the traditional uses to shed light on the design of their management and conservation strategies. Germplasm and data collection were conducted in the Caribbean and Andean regions of the country. This collection resulted in 750 accessions from 131 municipalities, belonging to 19 departments of the two regions. In these regions, sweet potato has been conserved in situ in a wide spatial and altitudinal distribution. The major collection sources were wild and cultivated habitats, which highlight the invaluable contribution of farmers and communities in the preservation of this species and its associated knowledge. In situ conservation seemed to be an efficient strategy for conserving and using plant genetic resources; therefore, it should be considered by conservation efforts.

“…Cold-tolerant species such as garlic, potato and most Mentha species can be kept viable at temperatures from 0 to 5 • C and 2 to 4 µmol m −2 s −1 for up to 24 months [46], whereas cold sensitive species such as many tropical plants should be stored at relatively high temperatures. Examples are Musa [47] (Figure 3, see Box 2) and sweet potato [48] both requiring a temperature of 15 • C or higher; for pineapple this is 21 • C [49]. Such higher storage temperatures result in shorter sub-culture intervals (six to twelve months).…”

The conservation of crop genetic resources, including their wild relatives, is of utmost importance for the future of mankind. Most crops produce orthodox seeds and can, therefore, be stored in seed genebanks. However, this is not an option for crops and species that produce recalcitrant (non-storable) seeds such as cacao, coffee and avocado, for crops that do not produce seeds at all; therefore, they are inevitably vegetatively propagated such as bananas, or crops that are predominantly clonally propagated as their seeds are not true to type, such as potato, cassava and many fruit trees. Field, in vitro and cryopreserved collections provide an alternative in such cases. In this paper, an overview is given on how to manage and setup a field, in vitro and cryopreserved collections, as well as advantages and associated problems taking into account the practical, financial and safety issues in the long-term. In addition, the need for identification of unique accessions and elimination of duplicates is discussed. The different conservation methods are illustrated with practical examples and experiences from national and international genebanks. Finally, the importance of establishing safe and long-term conservation methods and associated backup possibilities is highlighted in the frame of the global COVID-19 pandemic.
