ABSTRACT: Sorghum breeding significantly relies on the understanding of genetic diversity dynamics. Despite its importance, research on the geographical distribution of essential agro-morphological and phenological traits for achieving targeted breeding outcomes has been limited. This paper presents an analysis of five key traits—stem flavor, days to 50% maturity, plant height, grain color, and grain size—across 483 germplasm samples from 71 villages in Niger, based on data collected during a 2003 survey. The primary aim is to map the geographical distribution of these traits. The findings, illustrated on a map of Niger, provide insights into the regional distribution of these characteristics, aiding breeders and agronomists in understanding trait combinations for developing new sorghum varieties.
