Cultivar replacement-induced genetic improvement is considered an important factor in enhancing crop grain yield. However, the effect of cultivar replacement of foxtail millet, an important crop in arid and semi-arid regions, on grain yield and drought resistance has rarely been considered. In the present study, we grew five millet cultivars, representative of widely cultivated varieties released from the 1950s to the 2010s in Shaanxi Province, China, in an open rainout shelter (closed during rain events) under two contrasting water treatments (35 ± 5% field water capacity (FWC), and 75 ± 5% FWC) with an aim to detect yield-related parameters, biomass accumulation, water use efficiency (WUE), and plant water-related indices.
