Another strategy is to develop new forage legume production systems for improved livestock productivity with better nutrition. The system introduces vetch in rotation with a cereal to replace monocropping. Vetch provides good-quality feed for sheep and goats, besides raising yields of the following barley or wheat crop because of improved soil fertility and breaking the cycle of cereal diseases and pests. Vetch has been successfully introduced in China, Jordan, Morocco, Syria and Turkey. Participatory research, involving farmers in selecting crop genotypes, is increasingly used by ICARDA. For example, in Eritrea where farmers are selecting barleys for further development, the likelihood of variety adoption is much improved. More than 100 cultivars of barley developed from ICARDA-supplied germplasm have been released in 34 countries. Improving the nutritional and technological quality of wheat is another important objective in ICARDA's crop improvement work. Biotechnological tools permit the efficient use of the enormous amount of variability existing in the Center's collection of landraces. ICARDA's biotech team is working on Hessian fly-resistant durum varieties through the Dryland Durum Wheat Improvement Program, a joint effort with sister center, CIMMYT, and national partners in the region. Morocco has developed new durum cultivars resistant to Hessian fly, and is addressing the problems of root rot, leaf rust and wheat aphids; Tunisia is working on improving durum for resistance to drought; Algeria focuses on crop adaptation to the Atlas high plateau and on grain quality; while Turkey focuses on adaptation to severely-cold areas of the Anatolian plateau, crop nutritional disorders and grain quality.
