    摘要:

    2017—2018年“第三次全国农作物种质资源普查与收集行动”福建项目组对省内74个县(市、区)开展农作物种质资源的全面普查和征集,经过系统调查共收集到水稻地方品种资源148份,并进行了表型性状和稻瘟病抗性鉴定评价。调查发现,在福建闽西和闽北地区收集到的水稻资源数量远比闽东南沿海地区多,海拔4-1000m地区均有收集到水稻地方品种;表型鉴定结果表明:收集到的水稻地方品种中籼稻、粳稻,粘稻和糯稻数量相当;大多数品种表现为种皮白色、叶鞘绿色、颖尖秆黄色、颖色黄色,谷粒形状以阔卵形、椭圆形为主;收到的水稻地方品种数量性状遗传变异丰富,具有较大的挖掘潜力。鉴定评价获得抗稻瘟病资源有下洋粳稻、罗洋粳稻、丹阳糯稻、香春优种、宫占同安本、红米、红壳糯、黑米和红米仔9份。经综合评价筛选出香春优种、红米、红米仔、428、K28和长龙时谷6份优异水稻地方品种。本研究可为福建水稻地方品种的有效保护提供科学依据。

    Abstract:

    From 2017 to 2018, the Fujian team of the “Third National Crop Germplasm Resources Census and Collection Action” carried out a comprehensive survey and collection of crop germplasm resources in 74 cities/counties in the Fujian province, P.R. China. A total of 148 rice landraces were collected, followed by the characterization of phenotypic traits and rice blast resistance. The rice resources collected from western and northern was far more than that in the southeastern coastal areas of Fujian. Rice landraces have been collected in areas from 4 meters to 1000 meters altitude. Phenotypic character identification showed that indica rice and japonica rice, the non-glutinous rice and glutinous rice were found with similar amount. Most germplasms showed the characters such as white brown, green leaf sheath, yellow apiculus and yellow glume, and wide ovum or oval grain shape. The collected rice landraces were rich in genetic variation of quantitative traits and have great potential for mining. Nine landraces including Xiayangjingdao, Luoyangjingdao, Danyangnuodao, Xiangchunyouzhong, Gongzhantong’anben, Hongmi, Hongkenuo, Heimi and Hongmizi, were identified with rice blast resistance. Based on the phenotype, we screened out six superior varieties of Xiangchunyouzhong, Hongmi, Hongmizai, 428, K28, Changlongshigu. Collectively, this study would provide a scientific basis for the effective protection of Fujian rice landraces.
