摘要: 为挖掘海南普通野生稻耐旱资源,分别在长期自然条件下和防雨透光薄膜棚内对海南普通野生稻材料进行耐贫瘠和苗期、抽穗期耐旱性鉴定。结果发现672份普通野生稻耐贫瘠;25份苗期材料表现1级高耐旱且存活率大于80%,占5.1%;2份材料萎蔫率和耐旱空壳率皆≤5%,表现1级耐旱,占60份抽穗野生稻材料3.33%。这些耐旱普通野生稻资源分别来自文昌市、海口市、万宁市、澄迈县等地。

关键词: 海南普通野生稻, 耐旱, 苗期, 抽穗期, 鉴定, 筛选

Abstract: To collect samples and information, the drought-resistant germplasms of Oryza rufipogon Griff, which are indigenous to Hainan, at the seedling stage underfield conditions as well as at heading stage in a plastic shed were indentified.The results showed that 672 accessions were drought resistance under field conditions,and 25 accessions and 2 accessions respectively were high drought resistance at the seedling stage and heading stage.They were collected from Wenchang,Haikou, Wanning and Chengmai. The results would provide a reference for further study and breeding of new drought-resistant rice varieties in the future.

Key words: Oryza rufipogon Griff in Hainan, drought resistance, seedling stage, heading stage, identification, selection
