【摘要】 陆稻是山区及干旱地区最适宜种植的稻种类型,亦是水稻抗旱育种的宝贵资源。为了更充分研究及利用陆稻资源,通过对广西陆稻主要种植地区隆林各族自治县的陆稻进行调研、实地考察、宝贵陆稻资源收集以及性状鉴定,基本查清了隆林县陆稻的生产概况、类型、分布及生态环境,发现隆林县陆稻种质资源具有品种多样性丰富、耐贫瘠、适应性广、抗病虫性强、千粒重高、大粒种多等特点。此外,对陆稻今后的研究重点及应用前景进行了探讨,为进一步挖掘和利用陆稻资源,培育优良陆稻品种及抗旱水稻品种打下良好基础。更多还原

【Abstract】 Upland rice is not only the most suitable rice type for upland and drought areas,but also the valuable resources for drought tolerance breeding in rice.The present study was conducted to investigate the upland rice resources planting areas of Longlin County,Guangxi.The situation for production,type,distribution,and ecological environment for upland rice was found out.The results showed upland rice in Longlin County was characterized by plentiful varietal diversity,tolerance to infertility,wide adaptability,strong resistant to diseases and insect pests,higher 1000-grains weight,many varieties with large grain,etc.Further,in order to explore the upland and drought resistant rice for breeding,the research application prospects have been discussed.更多还原
