摘　　要：采用自然实生选种的方法,选出了高商品性荔枝新品种—‘荷花大红荔’。果巨大、单果重在精细管理条件下多为47.5-65.3g,最大果重90.0g,平均重52.9g。果正心形、龟裂片宽而平、皮色鲜红艳丽、肉质嫩滑、汁多味清甜,可食率79.0%。丰产稳产性能较好,幼年树1年可发6次梢,3月中下旬开花,果实发育和落果各有3个高峰期。根据RAPD分析及性状表现比较后发现‘荷花大红荔’综合经济性状优于现有的鹅蛋荔、紫娘喜、钦州红荔等巨大果型荔枝品种。因其果型巨大,栽培上应特别注意培养健壮的枝梢、合理的水肥供应及控制挂果的数量。Hehua Dahongli' is a high quality litchi cultivar, selected from litchi seedlings grown at Hehua Township, Gaozhou. Results from RAPD analysis and trait investigation indicated it had markedly different genetic background from other large-size-fruit cultivars like Edanli, Ziniangxi and Qinzhouhongli. It matures in late June. The fruit are straight heart in shape, with wide and flat segments and bright red skin, weighing 47.5-65.3 g and TSS around 17%. The flesh is tender, juicy and sweet with an edible rate of 79%. The trees are very productive. It is considered as the most ideal large fruit-sized and high quality cultivar in China. Judged by overall economic traits it is much better than the large fruit-sized cultivars, Edanli and Ziniangxie. Because of its large fruit size, it is important to foster strong fruiting shoot, manage water and fertilizer rationally, keep adequate loading, prevent fruit from cracking, and select suitable rootstock.
