Barley mutants for fodder production
Abstract
Barley is the fourth most important cereal crop and has the greatest agro-ecological range of any annual crop. It is an important food for humans and an important feed for a wide range of animals. Barley is an important crop in many parts of the world. The development of dual purpose varieties for food and feed holds great potential for alleviating hunger and poverty. Generally, barley provides an excellent balance of protein, energy, and fiber. The proposed research study should on the one hand compare diverse mutation methods (Gamma- and X-rays, and EMS treatments) in regard to induction of valuable food and feed quality traits. On the other hand existing barley mutants should be used to develop via rapid backcrossing isogenic lines with the desired characters into existing adapted varieties. The target mutant traits are: (1) hooded (Kap1) whereby the awns of barley are replaced by a hooded (a nutritious inverted spikelet) whereas the awns have no nutritional value and have negative feed effects as they cause lacerations in the mouths of animals, and (2) low-lignin content (rob1) as lignin inhibits the digestion of fodder.
