6个特种稻新品系在龙岩市的适应性评价

    Adaptability Evaluation of the 6 New Special Rice Strains in Longyan City

    • 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7 257.45 kg·hm-2,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6 565.05 kg·hm-2,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 7 257.45 kg·hm-2, 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 6 565.05 kg·hm-2, 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.
