摘　　要：莞福红荔枝是从东莞荔枝自然实生群体中选育出的优质荔枝新品种。其果实心形,果皮鲜红色,肉厚多汁,果肉蜡白色,浓甜微香,风味浓郁,品质优;单果质量29.3 g,可食率78.8%,可溶性固形物含量(w,后同)为19.6%,可滴定酸含量为1.09%,维生素C含量为264.0 mg·kg^(-1),比糯米糍迟熟7~10 d。果实品质优,不易裂果,丰产稳产性好,适合在广东省晚熟荔枝品种栽培区种植。Guanfuhong,a new litchi cultivar with excellent characteristics,was selected through the seedling selection.In 1993,maternal tree of Guanfuhong was initially selected for its large fruit size,a high and steady yield,a bright red pericarp,excellent quality,late-marurity and high quality in Dong-guan city,Guangdong province.After many-year regional trials,it was found that the genetic character-istic was stable.The new plant variety right was obtained in January 2023.The cultivar is a tall tree,with spreading growth habit and semi-circular canopy shape.Leaves are lanceolate,16.7 cm long and 3.9 cm wide.Inflorescence is conical;the main axis of inflorescence is 26.1 cm long and 13.9 cm wide.Flower is white with medium size.Guanfuhong can sprout new shoots all round the year,with young shoots growing about 5-6 times,while with fruiting trees they grow about 3-4 times.Fruit is mainly heart-shaped and the peel is red.The flesh is white with sweet flavor and aroma.The average fruit weight is 29.3 g;the horizontal diameter of fruit is 40.70 mm,the longitudinal diameter of fruit is 39.35 mm,and the number of seed is 1.The eatable rate of fruit is 78.8%.The soluble solids content is 19.6%and soluble acid is 1.09%.The content of vitamin C is 264.0 mg·kg^(-1).The fruit quality of Guan-fuhong is excellent.The fruit development period is about 80 d.And its maturity period is from late June to early July in Dongguan city,Guangdong province.It is resistant to both drought and water log-ging.The grafting compatibility between Guanfuhong and Huaizhi,Guiwei or Nuomici is high.In the third year after high-grafting,this cultivar can bear fruits,and the yield potential is high.The orchard should be established on acid red loam soil,which has good ability of moisture and fertilizer retention.Spacing in the rows and between rows is 6 m×8 m.The trunk is 0.3-0.4 m high with 3-4 main scaffold limbs,which are uniformly distributed with good growth vigor.Pruning should be carried out immedi-ately after fruit picking with adult fruiting tre
