Parent-Progeny Relationships for Carbon Isotope Discrimination and Related Characters in Crested Wheatgrass

Improved cultivars of perennial grasses developed for natural resource conservation and forage production on semiarid rangelands of western North America must persist under extreme environmental stress and make efficient use of limited water resources. A close negative relationship has been documented between carbon isotope discrimination (Δ) and water use efficiency (WUE) in temperate ( C3) grasses, and preliminary evidence indicates that Δ...
