Abstract: To understand the high yield, adaptability and quality characters of different naked barley varieties in the region along the Yangtze River and the coastal areas in Jiangsu Province, and select new naked barley varieties with good-quality and high-yield which are suitable for planting in these regions, we compared the biological properties, yield and its composition factors, stress resistance, amd quality of seven naked barley varieties and one barley variety. The results showed that: (1) as to growth stage, 7 naked barley varieties were suitable for planting in barley areas of Jiangsu Province,‘Tong mai 6’was a semi-winter variety, its sowing time was less flexible and it should be sowed early; (2) as to yield and stress resistance,‘Dong chen naked barley’was a six-rowed variety with less yield and poor lodging resistance, it was not suitable for being planted in Jiangsu Province,‘Su luo mai 2’had good yield, but was lightly infected by barley yellow mosaic disease, thus it could be planted in the field with less yellow mosaic disease in Jiangsu,‘Qing naked barley’ and‘Su luo mai 1’had good stable yield, resistance to barley yellow mosaic disease and were suitable for being cultivated in barley producing areas of Jiangsu; (3) as to quality,‘Qing naked barely’contained highβ - glucan, low crude fiber, higher starch and had good quality, it could be developed and used as special grains; ‘Su luo mai 1’and‘Su luo mai 2’contained higherβ -glucan, low crude fiber, higher starch, and had better quality, and could be developed and used as good-quality grains.
