摘　　要：‘Sc5’是由‘黄海棠’与‘SH5’杂交选育的苹果矮化砧木新品种。树冠较小,树势中庸,节间长2.1 cm。嫁接‘红富士’盛果期树高3.27m,冠径2.83m;树体嫁接口生长平滑,无气生根,嫁接品种与矮化中间砧干周比为0.97。嫁接‘长富2号’第2年结果株率65.3%,第5年进入盛果期,6~9年生树产量43290~57330 kg·hm^(-2),果实可溶性固形物含量16.8%,果肉硬度9.34 kg·cm^(-2)。该砧木矮化性与‘M26’相似,抗寒性优于‘M26’,适宜于黄土高原或类似气候地区栽培。‘Sc5’is a new cultivar of dwarf apple rootstock derived from Malus spectabilis×M.honanensis SH5.Its conopy size was small and the vigor was moderate.The length of internode was 2.1cm on average.The‘Red Fuji’cultivar in its adult stage on the interstock had a tree height of 3.27 m and a canopy diameter of 2.83 m.Its grafting position was smooth without air root.The ratio of trunk circumferences of scion and interstock was 0.97.There was 65.3%of‘Nagafu 2’on the interstock started fruiting in the second year.Mean yield of the‘Nagafu 2’from the 6th to 9th year was 43290–57330kg·hm^(-2)and the soluble solids content of fruit was 16.8%,the fruit hardness was 9.34 kg·cm^(-2).Compared to those of‘M26’,the degree of dwarfing of‘Sc5’was similar and the cold hardness was greater.‘Sc5’is suitable for apple production in the Loess Plateau and regions with similar climate.
