Therefore, the chiru attracted a lot of attentions of the Chinese government, conservation scientists and other conservative organizations in the world.In the present study, 57 chiru individuals were sampled from Arjin Shan Nature Reserve in Xinjiang, Chang Tang Nature Reserve in Tibet and Kekexili Nature Reserve in Qinghai. The present study, based on the analyses of the chiru mitochondrial control region with MEGA, DnaSP and ARLEQUIN programs, investigated into the genetic diversity background, evolutionary history and population relationships and aimed to provide scientific basis for the protection of the chiru.

The content of mineral elements in ripe fruits of M.sieversii from 78 seedings at Mohe Town,Gongliu Country were analyzed using Atomic Absorption Spectrophotometer.The results indicated that M.sieversii seedings presented considerable genetic variations in content of mineral elements with the range of variation coefficients from 24.2% to 54.0%.So it has large potential for further selection.Four elite seedlings were selected,namely large fruit type,high Ca content type,high Zn content type and high damascenone content.As the predominant component of Ily wild fruit tree forest,Malus sieversii had occupied an area of 9300ha.But the inherent reproduction system of M.sieversii and genetic diversity of the species were destructed in different degrees,as a result of farming assart,over grazing and damage by Agrilus mali.

上述结果支持"新疆野苹果可能是栽培苹果祖先种"的结论；②对巩留县莫舍乡的新疆野苹果78个实生株系果肉组织Ca、Mg、Fe、Zn、Cu、Mn6种矿质营养元素进行测定的结果表明，每种矿质元素含量单株间差异显著，变异系数在24.2％～54.0％，遗传多样性丰富，进一步选择的潜力很大；③根据新疆野苹果果实形态、香味物质和矿质元素含量等的测定结果，初步筛选出了大果型、高钙型、高锌型和大马酮型等4个特异性状单株；④调查发现，由于农田开垦、过度放牧以及苹果小吉丁虫的蔓延危害，目前伊犁野果林面积逐年减少，野苹果固有的繁育体系和遗传多样性受到不同程度的破坏。
