摘　　要：‘中石榴5号’是以‘中石榴1号’为母本,‘突尼斯软籽’为父本杂交选育而成的超软籽新品种。果实近圆形,特大果型,平均单果质量494.7 g,纵径89.30 mm,横径96.6 mm;果皮光洁明亮,果面鲜红色,果皮厚度3.52 mm;籽粒红色,汁多味甜酸,百粒重53 g,核仁超软(硬度1.22 kg·cm^-2);可溶性固形物含量17%,可溶性糖13.74%,抗坏血酸含量18.0 mg·100g^-1,总酸(以柠檬酸计)2.26 g·kg^-1,氨基酸总量7.30 g·kg^-1,品质优良。河南郑州9月下旬成熟,容易成花结果。该品种树势强健,树姿开张,树冠半圆形,枝条半直立,主干灰褐色。‘Zhongshiliu 5’,selected by ZhengZhou Fruit Research Institute of Chinese Academy of Agricultural Sciences,is a new super soft-seed pomegranate variety.We selected it from cross-fertilize between‘Tunisiruanzi’which was introduced to China in 1986 and‘Zhongshiliu 1’which was selected in 2000.Cross-fertilize were proceeded in 2004.Hybrid fruits were obtained on September 2004,and then seeds of fruits were hid in sand for the winter.Seeds were germinated and sowed in April 2005.1163 hybrid seedlings were obtained eventually.The hybrid seedlings were planted in resources nursery of ZhengZhou Fruit Research Institute of Chinese Academy of Agricultural Sciences with 0.5 m×2 m distance between plants in March 2006.They were managed under conventional management.Fruits were observed firstly in 2008,The plant growth characteristics and fruit traits were investigated in 2008—2010.One pomegranate superior stain numbered‘03-01-103’was selected which has the advantage of super soft-seed,high yield and other aspects of outstanding performance temporarily named‘Zhongshiliu 5’officially.In 2011 more than 2000 seedlings were obtained by grafting and rapid propagation technology.The experimental orchard of‘Zhongshiliu 5’superior line was established.In the spring of 2013,170 pomegranate trees were grafted in Gaochun town of Xingyang city.The distance between them was 3 m×4 m.Then regional adaptability testing of this optimal system was at Xinan district in Luoyang city,Shanyang district in Jiaozuo city,and Xichuan district in Nanyang city with more than 300 strains,spacing 2.5~3 m×4 m.Moreover,‘Tunisiruanzi’was cultured as control.After continuous observation for many years,the characters of‘Zhongshiliu 5’were fruit large,super soft-seed,high yield,and perfect appearance.Fruit average weight was 494.7g.The appearance of the strain was pretty.The fruit was nearly round,and the fruit peel was bright and clean.The fruit surface was red.The coloring rate was over 85%,and fruit cracking was not obvi
