Abstract：From 2020 to 2024，a folk-based selection of Ziziphus jujubeLingwu resources was carried out in Lingwu City，Ningxia.Indicators such as fruit size，moisture content， soluble solid content，hardness，sugar-acidratio，vitaminC，yield，maturityperiod，andjujubethorns traitswere measured and11 excellnt clones of Ziziphus jujubeLingwu were selected.In 2024，comparative tests were continued on the 11 re-selected excelent clones of Ziziphus jujube Lingwu.Various fruit indicators were tested，and through significance analysis and comprehensive evaluation using principal component analysis，the excellnt clones that were initially screened out for their high quality，high yield，large single fruit weight，earlymaturitywere 038，039，032，022，002，033，030 and 016.Meanwhile，clones showing the characteristic of extra-early maturity were OO2， O33 and 034;those without jujube thorns traits were O16，032 and O34;those with small and few jujube thorns traits were O33，O39and O30;and those with good high yield potential and large fruit-setting amountwere038，032，033，039，002，015，022 and 070.
