The morphological diversity of fruits in 3 intraspecific populations(Daxigou in Houcheng county,Kuerdening in Mohe town Gongliu county and Jiaowutuohai in Xinyuan county,all the sites are in Ily State) of Malus sieversii was investigated,as well as the existence status.Combining Content of volatile compounds and mineral elements,we selected 4 elite seedlings from all 132 seedlings.The aim of this study was to provide original data for consideration of origin and evolution of Malus domestica and scientific theory of conservation and utilization of M.sieversii.The results indicated that fruit shape,size,color and length of carpopodium have great morphological diversity with the variation coefficient of more than 10%.The range of fruit weight was from 9.95 to 47.47g in Mohe population in Gongliu county,while the variation coefficient was 29.71%.The results above support the conclusion 'M.sieversii was assumed progenitor of domesticated apple M.domestica'.The content of mineral elements(Ca,Mg,Fe,Zn,Cu,Mn) 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.So we suggested establishing a multi conservation system which combines original site,non-original site,ex-situ conservation and utilization conservation on M.sieversii.
