2016-2018 年“第三次全国农作物种质资源普查与收集行动”广东省项目组对省内 59 个县(市、区)的水稻地方品 种资源进行了系统调查与收集,共收集到水稻资源 269 份,并对其中的 261 份进行了鉴定评价。调查发现,收集到的水稻地方 品种资源基本遍布整个广东地区,在珠三角周边的深圳市、东莞市、中山市和珠海市等 4 个地级市未收集到水稻地方品种资 源。对收集的水稻资源进行农艺性状鉴定,结果表明:收集到的水稻地方品种主要以籼稻为主,鉴定评价获得抗水稻白叶枯 病与稻瘟病资源 23 份(中山 12、包选 2、银湖香占等)。综合表型性状筛选出海稻 86、地禾粘、兰溪选、三饶香米等 4 份分别具 有耐盐、耐旱、高直链淀粉与香味等特性的水稻地方品种资源,对水稻育种种质改良,选育高产、优质、广适的新品种有较高的 利用价值。
From 2016 to 2018,the project team of Guangdong province of the Third National General Survey and Collection Action of Crop Germplasm Resources conducted a systematic investigation and collection of rice germplasm resources from 59 counties(cities and districts)in the province. A total of 269 rice landraces were collected and 261 of them were identified and evaluated. The rice landraces were collected from almost throughout Guangdong province,with the exception of four prefecture-level cities around the Pearl River Delta: Shenzhen,Dongguan,Zhongshan and Zhuhai,where no rice germplasm resources were found. The agronomic traits of the collected rice resources were identified. The results indicated that the collected rice landraces were mainly indica rice,and 23 rice germplasm resources(Zhongshan 12、Baoxuan 2、Yinhuxiangzhan,etc)resistant to bacterial blight and blast were evaluated. Finally,4 rice germplasm resources with salt and drought tolerance, high amylose and aroma:Hai Dao 86,Di He Nian,Lanxi Xuan and Sanrao Xiangmi,were selected based on the overall phenotypic traits,which had high utilization value for improving rice breeding for high yield,high quality and wide adaptability in the future.
