摘　　要：‘红日梨’是由‘红茄梨’和‘苹果梨’杂交选育出的中熟梨新品种。果实扁圆形,果皮红色,果面光滑,具蜡质,果肉白色,采收时果肉脆,后熟后肉质变软,风味酸甜,香味较浓;平均单果质量280 g,最大单果质量520 g,果形指数0.89;每果实含种子7粒。可溶性固形物含量13.5%,总糖含量9.366%,可滴定酸含量0.38%,糖酸比24.6,维生素C含量38.9 mg·kg-1;品质上。果实生育期130 d,在辽宁熊岳地区(东经122°8′55″、北纬40°10′34″)9月上旬果实成熟;每花序8.7朵花,萌芽率70.2%,成枝力2.8。抗逆性较强,抗枝干病害能力较强。货架期5 d,冷藏5个月。适合鞍山以南地区栽培。‘Hongri＇ is a new mid-ripening pear eultivar released by Liaoning Institute of Pomology result- ed from a cross of ‘Red Clapp＇s＇ x ‘Apple-pear＇. Two hundred and thirty hybrid seeds were harvested from above cross combination in the fall of 1993 and 119 seedlings were bred in 1994. Young seedlings were replanted in 1995. One seedling was selected and identified as primary selected line coded as 93-6- 50. Branching grafting and propagation were carried out in 2002. Twenty five seedlings were replanted in reselection site of our institute and tested in the regions in Tieling, Shenyang, Liaoyang, Anshan and Yingkou of Liaoning in 2004. The trees of ‘Hongri＇ are vigorous and semi-spreading with scaled, rough and dark brown trunk. One-year-old branches are maroon with internode at 3.6 cm length and the leaf buds are oblique. Young leaves are pale red and ripe leavesare ovoid with petiole 3.22 cm in length, The average length of leaves is 11.84 cm and width is 5.46 cm with apiculate tips and serrated margins. There are 8.7 flowers in each inflorescence, and the average number of stamens is 20. Stigma and anthers have similar length with pale purple anthers. Fruit are oblate and smooth with white flesh and small core. Above 50% fruit surface are red （without bagging） with red sunny side from the young fruit period and yel- low-green ground. Flesh is crisp, juicy, sweet and sour 3 to 4 d after harvesting and begin to soften with less stone cells and slight fragrant after 3 to 4 d ripening. The average fruit weight is 280 g with the largest fruit is 520 g and fruit shape index is 0.89. The quality of fruit is good with soluble solid content at 13.5%, titration acid content at 3.8 g.L-1 and vitamin C content at 38.9 mg·kg^-1. The fruit ripened in early Septem- ber with 125 d development period. The germination rate of one-year-old branches is 70.2% with the ex- tend of branching at 2.8. Axillary buds accounted for 24%. Each inflorescence have 1.8 fruit in average.The tree of ＇ Hongri＇ begin to fru
