摘 要：为掌握岩红301、岩黑302、岩紫787、连城黑糯、岩黑305、岩黑306等6个特种稻新品系的特征特性与产量表现，以宜优673为对照，采用单因素随机区组设计，对各品系的农艺性状、抗病性、抗倒伏性和产量表现进行了综合考察。结果表明：岩紫787产量达7257.45 kg·hm2，抗病性好，抗倒伏，在所有参试品系中表现最好，岩黑302次之，两个品系均可作进一步开发利用，连城黑糯产量6565.05 kg·hm2，产量尚可，但抗病性稍差，需作进一步考察，岩黑305、岩黑306产量低、抗病性差，直接开发利用价值小，建议作为育种中间材料使用。

Abstract： In order to understand the characteristics and yield of the six new special rice strains including Yanhong 301， Yanhei 302， Yanzi 787， Liancheng Heinuo， Yanhei 305 and Yanhei 306， by taking Yiyou 673 as the control group， the agronomic traits， disease resistance， lodging resistance and yield performance of each strain were comprehensively investigated by using the single factor randomized block design. The results showed that the yield of Yanzi 787 reached 7257.45 kg·hm2， with good disease resistance and lodging resistance， which was the best among all the tested strains. And the second was Yanhei 302. Both of the strains could be further developed and utilized. The yield of Liancheng Heinuo was 6565.05 kg·hm2， which was acceptable， but the disease resistance was a little poor， which needed to be further investigated. Yanhei 305 and Yanhei 306 had low yield and poor disease resistance， and their direct development and utilization value was small， so they were recommended to be used as the intermediate material for breeding.Key words： Special rice; Strain; Screening; Longyan City

我國从20世纪80年代开始广泛关注特种稻种质资源研究[1]。至今以丰富的特种稻种质资源为基础，在积极开展特种稻特殊性状遗传分析的同时，将常规育种与生物技术相结合，创新出了黑米、红米、软米、巨胚米、甜米等一系列特种稻新种质[2-14]，并在水稻育种和生产上提供应用，为经济社会发展做出了积极贡献[15-16]。但是，综观前人的研究成果，仍然存在育成的特种稻品种产量不高、病虫害抗性普遍较差、米质适口性一般等问题。为此，龙岩市农业科学研究所特种稻育种课题组近年来一直专注于优质、多抗、高产特种稻新品种选育工作，并成功培育出了一批特种稻新品系。为加快这批特种稻新品系的推广应用进程，课题组对岩红301、岩黑302、岩紫787、连城黑糯、岩黑305、岩黑306等6个强优势特种稻新品系进行了较为系统的对比筛选，以期为这些品系的进一步开发利用提供科学依据。……
