Efficiency of nitrogen and phosphorus utilization in progenies of factorial crosses between European and exotic cultivars of spring barley (Hordeum vulgare L.).

Abstract excerpt

Previous observations suggested that some landraces, primitive cultivars and other barleys originating from the harsh conditions of the Middle East, North Africa and Tibet might serve as interesting sources of adaptation to low-input agriculture. This opportunity was verified in field experiments performed under reduced rates of nitrogen (N) and phosphorus (P) fertilization. Genetic variation in major components...
