Morphological Variation and Basic Characteristics of Selected Indigenous
Rhizobia Isolated from Major Chickpea (Cicer arietinum L.) Growing in
Regions of Ethiopia
Author(s): Zehara Mohammed Damtew*
Chickpea (Cicer arietinum L.) is a major legume crop in Ethiopia and provide multiple benefits, due to high nutritive
value as well as the ability of the crop to enrich nitrogen poor soils due to biological nitrogen fixation with different Rhizobia isolates. However, the effectiveness of the isolates varies due to inherent feature, stress tolerance and substrate
utilization characteristics of the isolates. This necessitates the screening of the basic properties of the isolates under in vitro laboratory conditions. To this effect, 15 indigenous isolates from chickpea growing regions were tested for in vitro basic features, stress tolerance and substrate utilization properties. There were variations in morphological
features, stress tolerance and nutritional diversity among isolates. The isolates also formed colony with circular
shape,.. View more»
