摘　　要：采用抗性强且丰产性较好的7个品种进行田间小区试验,评价和筛选抗(耐)连作大豆品种。试验结果表明,抗线5号较其它6个品种出苗率高,根表胞囊线虫雌虫数量较少,产量最高,为2298kg/hm2,各项产量构成因素表现得也最好。合丰47的大豆根腐病和黑农48的叶部灰斑病发病程度最轻,但产量较低。In order to evaluate and screen varieties against continuous cropping soybean, seven varieties with good resistance and high yield were adopted in by compared plot in the field in 2007. The results showed that the seeding rate of Kongxian 5 was higher than other six varieties, the number of soybean cyst nematode females on the roots was fewer, its yield was highest in seven varieties which reached 2 298 kg per hectare and the characters of soybean yield were better. Soybean root rot of Hefeng 47 and frogeye leaf spot indexes were lower than other six varieties, but their yields were lower.
