INTRODUCTION Orphan crops have been underutilized in modern agriculture and are cultivated in a limited number of regions (Ye and Fan, 2021). Compared with staple crops, orphan crops possess many beneficial traits, such as being more nutritious and well adapted to unfavorable environments, and therefore have great potential for sustainable agriculture (Yaqoob et al., 2023).

Abstract Breakdown of reproductive isolation facilitates flow of useful trait genes into crop plants from their wild relatives. Hybrid sterility, a major form of reproductive isolation exists between cultivated rice (Oryza sativa) and wild rice (O. meridionalis, Mer). Here, we report the cloning of qHMS1, a quantitative trait locus controlling hybrid male sterility between these two species.
