‘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3.27 m,冠径2.83 m;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43 290 ~ 57 330 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 2.1 cm 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 43 290-57 330 kg · 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.
