摘　　要：‘桂荔1号’是从广西荔枝优良实生变异单株中选育出的荔枝新品种,2015年6月通过广西农作物品种审定委员会审定。该品种表现外观好、适应性强、品质优和丰产稳产,果肉质地软滑、不流汁,平均单果质量为29.0 g,可食率为68.0%,可溶性固形物含量18.0%。在广西平南县1月下旬开始出现花序原基,抽穗期为2月中下旬,开花期4月上中旬,果实成熟期为7月上中旬。该品种适宜在广西荔枝产区推广种植。＇ Guili No. 1＇ is a new litchi cultivar selected from the mutant progeny of excellent Guangxi litchi . This cuhivar was originally named ＇Champion Red＇, and was a litchi mutant seedling produced by litchi Team 2 from Guaneheng village, Guancheng town, Pingnan county, Guangxi province. Since 1994, robust bud sticks have been obtained from the ＇Champion Red＇ litchi parent plant and used for grafting, followed by investigations of the resulting plants＇ biological characteristics and fruit quality for several years. The results showed that their genetic traits were stable. SSR molecular markers was performed on the plant materials of ＇Guili No. 1＇ and 14 other litehi varieties to analyze their phylogenetic relationships. The results revealed that ＇Guili No. 1＇ was a new litchi cultivar that was different from the other tested cultivars, but had the highest similarity coefficient with ＇Guiwei＇. The cultivar was reviewed and approved by the Guangxi Committee of Crop Variety Registration in June 2015. In Pingnan County, Guangxi, ＇Guili No. 1＇ begins to develop inflorescence primordia in late January. The heading date occurs in mid- to late February, the flowering stage occurs in early to mid-April, and the fruit maturation stage occurs in early to mid-July. This litchi cuhivar has superior fruit quality and a higher and more sta- ble yield compared to the local dominant late-maturing cultivar ＇Heli＇. ＇Guili No. 1＇ has heart-shaped fruits that have a red rind. The edible flesh is wax-white, with a creamy texture, uniform color, and dry aril. The average weight of individual fruits is 29.0 g, and these have an edible portion of 68% and soluble solids content of 18%. In addition, the fruits have a clear and sweet taste, and are tolerant to storage and transportation. Fruiting generally starts 3-4 years after grafting, and each plant can produce 180-200 kg of fruit during periods of high yield. There were no significant fluctuations in production rates from year to year. ＇ Guili No. 1
