Agro-morphological diversity of Ethiopian sorghum [Sorghum bicolor (L.) Moench] landraces under water limited environments

Drought stress is one of the major constraints affecting sorghum [ Sorghum bicolor (L.) Moench] production in rain-fed regions of the Semi-Arid Tropics. Ethiopia is the suspected center of origin for sorghum and as such has tremendous variability for a wide range of traits. Ironically, there has bee...

Description
Summary:Drought stress is one of the major constraints affecting sorghum [ Sorghum bicolor (L.) Moench] production in rain-fed regions of the Semi-Arid Tropics. Ethiopia is the suspected center of origin for sorghum and as such has tremendous variability for a wide range of traits. Ironically, there has been little systematic characterization of Ethiopian sorghum for traits of agronomic interest including drought tolerance. Hence, the objectives of this study were to evaluate the phenotypic diversity of 315 sorghum accessions (314 landraces plus 1 standard check) collected from farmers’ fields of diverse geographic regions in Ethiopia, and to identify potential sources of drought tolerance for future breeding programs. We phenotyped these accessions for ten agro-morphological traits at two water limited environments (Kobo and Mieso). Significant ( p
