In sub-Saharan Africa and in Madagascar, upland rice is mostly grown for subsistence by resource-poor farmers in low-input production systems with low yields. In this context, soil nitrogen availability is a major limiting factor. To determine the appropriate breeding strategy to improve nitrogen use efficiency (NUE), the genetic variability and the level of G × N interaction of NUE need to be ...
