SH系列苹果矮化砧木系国光×河南海囊种间杂交育出的苹果无性系自根砧,对照为M_9,M_7,MM_(106)无性系自根砧和山定子实生砧,嫁接品种为羽红(3号 红星)、金冠、富士等.1987年杂交,1982年秋定植于鉴定圃.经过5年的生物学特性、物候期及园艺学性状观察,以及矿质营养,净光合效率,气孔阻力,蒸腾强度,ABA含量等分析测定,4100个砧木杂交单系中选出SH系列苹果矮化砧木.本文报道的是SH系列中SH_3、SH_4、SH_5、SH_9、SH_(12)、SH_(14)、SH_(15)、SH_(20)、SH_(21)、SH_(29)等10个突出的优系砧木.它们的共同性状表现为早花早果,树体矮化、半矮化,抗逆性强(抗旱、抗倒伏、抗抽条),早期丰产稳产,果实着色浓红艳丽,含可溶性固形物高,风味浓,品质好,果实硬度大耐贮藏,容易繁殖,综合性状超过对照M_9、M_7、M_(106)和山定子的苹果矮化砧木新系列.
SH series apple dwarfing rootstocks Guoguang × Henan sea buckthorn interspecific hybrid clones of self-rooted apple clones, the control M_9, M_7, MM_ (106) clones of self-rootstocks and mountain statins, grafting varieties for the feather Red (No. 3 Red Star), Golden Delicious, Fuji etc .. 1987 hybridization, planted in the identification garden in autumn 1982. After 5 years of biological characteristics, phenological and horticultural traits observed, as well as mineral nutrition, net photosynthetic efficiency, stomatal resistance, (SH), SH_5, SH_9, SH_ (12), SH_ (14), SH_4, SH_4, SH_4, SH_4, SH_4, SH_4, SH_4, SH_4 and SH_4 in the SH series were selected from 4100 rootstock hybrids. SH_ (15), SH_ (20), SH_ (21) and SH_ (29), etc. The common traits of them were early flowering early fruit, dwarf tree, semi-dwarf, Strong resistance (drought resistance, lodging resistance, anti-drawing), early high yield and stable yield, fruit coloring thick red gorgeous, with soluble solids, rich flavor, good quality, fruit firmness and storage, easy to breed, M_7, M_ (106) and the mountain of apple dwarf rootstock new series.
