HULL-LESS BARLEY: THE STATE OF STUDY AND PROSPECTS OF USE

Blog Article

The main places of growing of hull-less barley varieties are considered to be the South-East Asia, mountainous Central and West China with its lowlands.These are the places where there is a great variety of hull-less barley.The data received with a radio isotope method show that hull-less barley dates back to 7900 years B.C.Thus, hull-less Beast Wars barley appeared significantly later than chaffy barley, which grew in the Pre-Pottery Neolithic (9700-9300 years B.

C.).Barley grain is used for making different groats.Barley groats is grain with removed hulls, processed according to a kind of groats.The volume of groats depends on a structure of starch and amount of hulls.

The grain of hull-less barley is free from the hulls and mostly glassy, so the volume of groats received from hull-less barley is much more than from chaffy barley.Barley and pearl barley are made from barley grain.Besides hull-less barley is used as a valuable fodder, especially for monogastric animals.Nowadays the breeding of hull-less barley varieties is being carried out in Canada, Japan, US and Sweden.Comparing chemical structure of hull-less and chaffy barley, we must Doll note that hull-less barley prevails the other one, except in a content of cellulose.

In the foreign scientific works the prior tasks for study are the problems of domestication of hull-less barley, its varieties, tolerance and resistance to pests and diseases.Native literature is devoted to the problems of practical breeding, study of green mass and grain of hull-less barley.
