摘要

Novel germplasm is becoming increasingly important for developing crop varieties with high yield potential, better quality and abiotic or biotic resistance. Annual wild barleys, H. spontaneum, H. agriocrithon and H. paradoxon, which mainly exist in the Near East Fertile Crescent and Qing-Tibetan Plateau, share the same genome as cultivated barley does and are completely fertile between interspece crosses. We have systematically evaluated important agronomic, biological and quality traits from more than 200 annual wild barley accessions from QingTibetan Plateau since 1978 by integrating cytology, physiology, biochemistry, genetics, conventional breeding techniques and modern biotechnology. We have successfully identified and created germplasm with early maturity, male sterility, high protein, specific malting quality, salt and aluminium tolerance, including 69 accessions with pre-harvest spouting tolerance; 20 accessions with aluminium resistance; 7 accessions with salt tolerance and 2 accessions with drought tolerance. Some of them have been successfully used in the barley breeding programs, such as Chuanluo No. 1 (early maturity and dwarf); 88Bcms (male nucleo-cytoplasmic sterile line) and 5199 (extreme-early heading and cold-resistance). Thirteen commercial barley varieties were released with the genes from the annual wild barleys during 1992-2011, indicating the great potential of the annual wild barleys in Qing-Tibetan Plateau for the genetic improvement. The new varieties have successfully solved the land limitation issue of growing barley in the Yangtze valley and promoted the development and utilization of winter fallow field and efficient use of land resources in cotton and corn throughout the year.
