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.
