“…For example, rapid cycling can be used to advance lines quickly as shown in an F 2 population derived from a cross between L. culinaris Medik. and L. ervoides (Lulsdorf & Banniza, 2018). Past research shows marked genetic variability for desired traits among landraces and wild lentils.…”

Legumes represent the second most important family of crop plants after grasses, accounting for approximately 27% of the world's crop production. Past domestication processes resulted in a high degree of relatedness between modern varieties of crops, leading to a narrower genetic base of cultivated germplasm prone to pests and diseases. Crop wild relatives (CWRs) harbor genetic diversity tested by natural selection in a range of environments. To fully understand and exploit local adaptation in CWR, studies in geographical centers of origin combining ecology, physiology, and genetics are needed. With the advent of modern genomics and computation, combined with systematic phenotyping, it is feasible to revisit wild accessions and landraces and prioritize their use for breeding, providing sources of disease resistances; tolerances of drought, heat, frost, and salinity abiotic stresses; nutrient densities across major and minor elements; and food quality traits. Establishment of hybrid populations with CWRs gives breeders a considerable benefit of a prebreeding tool for identifying and harnessing wild alleles and provides extremely valuable long-term resources. There is a need of further collecting and both ex situ and in situ conservation of CWR diversity of these taxa in the face of habitat loss and degradation and climate change. In this review, we focus on three legume crops domesticated in the Fertile Crescent, pea, chickpea, and lentil, and summarize the current state and potential of their respective CWR taxa for crop improvement.

“…Nature BiotechNology around 15 d when compared with harvesting mature seeds. A similar approach has also been applied in lentil (Lens culinaris) 66 . Even earlier harvesting is possible by using embryo rescue; from 12 d post-anthesis, a germination rate of 100% can be achieved after 2-3 d of culture 67 (Fig.…”

“…Protocols have also been developed for grass pea (Lathyrus sativus; Fig. 1b), lentil and quinoa to expedite breeding and research, which could soon lead to new varieties (Mobini et al 2015;Ghosh et al 2018;Lulsdorf and Banniza 2018). carried out parental crosses and grew F1 plants in the field, and then successfully used speed breeding to inbreed the F2, F3 and F4 generations within 12 months.…”

“…Techniques for rapid cycling can include any combination of the following approaches: optimising the plant growth environment (e.g., plant density, photoperiod and temperature), genetic engineering targeting the flowering pathway, grafting juvenile plants to mature rootstocks, applying plant growth regulators and harvesting immature seed 6 (O'Connor et al 2013;van Nocker and Gardiner 2014;Ceballos et al 2017;Ghosh et al 2018;Lulsdorf and Banniza 2018).…”

This review explores how speed breeding protocols that hasten plant growth and development could be applied to shorten breeding cycles and accelerate research activities in orphan crops. Authors' contribution: LTH and WP conceived and outlined the review; TC and WP contributed technical knowledge of breeding orphan crops; SK contributed concepts and technical knowledge for converting shipping containers into speed breeding capsules; LTH contributed technical knowledge of speed breeding; TC, SK, WP, and LTH wrote the manuscript. Acknowledgements: We are grateful to Graeme Wright (Peanut Company of Australia) for providing a photograph of peanut plants growing under speed breeding conditions (Fig. 1a) 2 and Cathie Martin and Abhimanyu Sarkar (John Innes Centre) for providing a photograph of grass pea growing under speed breeding conditions (Fig. 1b). The authors would like to thank the Australian Research Council for support through an Early Career Discovery Research Award to Lee Hickey (DE170101296).
