海南原生荔枝种质资源收集保存及主要性状评价

摘要

Based on the investigation,60 native Litchi germplasms in Hainan had been collected and conserved in the Litchi Germplasm Nursery of Hainan Academy of Agricultural Science,whose characters such as flowering rate,flower number,fruit weight,fruit maturity,yield per plant,fruit appearance,fruit interior quality etc.were evaluated.The results showed that 11 germplasm resources,Haiken 13,Yamulong,Xinqiumili,Chun 25,Nongmei 9,Dadingxiang,Haiken 26,Haiken4,Qiongshan 89-3,A4 wuheli and Nandaowuhe respectively,reached a better comprehensive performance and wider application prospects.The study provides references to the collection,evaluation and creatively utilization of native litchi germplasms in Hainan,playing an important role in selecting and breeding of litchi.%通过资源调查,海南省农业科学院热带果树研究所荔枝资源圃收集保存了60份海南原生荔枝种质资源,对这批种质成花率、开花量、单果重、果实成熟期、单株产量、果实外观、内在品质等性状进行评价。结果表明,海垦13号、鸭姆笼、新球蜜荔、春25号、农美9号、大丁香、海垦26号、海垦4号、琼山89-3、A4无核荔、南岛无核等11份种质综合表较好,具有广阔的推广应用前景。该项研究为海南原生荔枝种质资源收集、评价与创新利用提供了参考,在荔枝选育种工作中具有重要意义。
