摘　　要：在衡阳县进行品种筛选试验,以考查新引进的20个粳稻品种在当地的适宜性和生产性能,筛选耐低温品种,为晚粳稻在湘南推广种植提供依据。结果表明:与迟熟组对照丰源优299比较,杂粳2号、南粳47、晚粳29、晚粳19、晚粳博5、杂粳5号均有7%以上的增产幅度,与中熟组对照湘丰优9号相比较,杂粳2号、南粳47、晚粳29均有4%以上的增产幅度。综合主要经济性状与抗性表现,杂粳2号、南粳47、晚粳29、晚粳19等品种产量高,生育期适宜,抗性好,适合在衡阳推广种植。To examine the suitability and production performance of 20 newly introduced rice varieties, to screen low tem- perature resisting varieties, a screening test was carried out in Hengyang County. The results show that： compared with the late maturing group Fengyuanyou 299, varieties including hybrid Zajing 2, japonica Nanjing 47, late japonica Wanjing 29, late japonica Wanjing 19, late japonica Bo 5, japonica Zajing 5 all have more than 7% increase in yield, compared with the middle - season rice Fengxiangyou 9, hybrid japonica Zajing 2, japonica Nanjing 47, late japonica Wanjing 29 all have more than 4% increase in yield. In conclusion, the major economic traits and resistance performance of hybrid Zajing 2, japonica Nanjing 47, late japonica Wanjing 29, late japonica Wanjing 19 are suitable for planting in Hengyang.
