Morpho-physiological and yield traits for selection of drought tolerant grass ecotypes.

Drought has become more recurrent and causes a substantial decline in forage yields leading to strain on feed resources for livestock production. This has intensified the search for drought-tolerant forages to promote sustainable livestock production. The objective of this study was to identify drought-tolerant grasses and to discern their morpho-physiological and yield traits to water stress as well as the relationship between these traits and indices of drought resistance.
