摘要/Abstract

摘要： 红肉蜜柚系选育于琯溪蜜柚园中的优变株系,其果实成熟期、汁胞呈色显著不同于琯溪蜜柚,而其它生物学特性则与琯溪蜜柚难于区别;两者混栽或人工授粉均表现不亲和性,而授两者以外品种花粉,果实均能形成大量发育或发育不完全的种子,同时,两者花粉形态特征相似;ITS-PCR扩增片段大小一致、条带单一,进一步证实两者亲缘关系相近,不存在种间、近缘属间差异。由此推测,红肉蜜柚源自琯溪蜜柚芽变。

关键词: 红肉蜜柚, 琯溪蜜柚, 亲缘关系

Abstract: Red-fleshed sweet pomelo was originated from the high-quality bud sport of Guanxi sweet pomelo.The fruit mature period and the color of juice vesicle were different from Guanxi sweet pomelo, but other biological characteristics were similar to Guanxi sweet pomelo.They showed incompatibility when used the methods of mixed culture or artificial pollination each other.But pollinated with other cultivars' pollen, the fruits of red-fleshed sweet pomelo and Guanxi sweet pomelo could form many developed seeds or rudimentary seeds.Their pollen morphological characteristics were similar.Amplified fragment length of ITS-PCR was accordant, and bands were single in the two cultivars.These indicated that they have close genetic relationship, and red-fleshed sweet pomelo was originated from the bud sport of Guanxi sweet pomelo.

Key words: red-fleshed sweet pomelo, Guanxi sweet pomelo, genetic relationship
