Abstract: 300 pieces of idioplasm resources of the Tibetan edible cultivation spring naked barley is identified for characteristic of shape, agronomic characters, rust-resisting property and grain thick protein, β-grape polymerization sugar and Vitamin E and so on from the Tibetan different region, which are analysed result in, for one thing, multiplicity of Tibetan spring naked barley is quite rich for the variation of the awn, leaves and the grain color, and multiple property are highest; Secondly, it has some fine hereditary characters of early maturation, big spike, many grains, many arrises and the strong anti-rust quality; Thirdly, genetic potential which is used possibly is enormous for characteristic of dense spike, exiguous spike, naked grain , the hook awn, short stem, the anti-rust and so on ; Fourthly, thick protein, β-grape polymerization sugar and Vitamin E of grains are rather difference to environmental condition of the various areas. Many kinds of genetic resources of fine characteristic are filtered by studying, and provides fine idioplasm which can be used for breeding and studying genetic resources.
