优质中籼新品系262在1984,1985年对多种病虫害的抗性鉴定结果是高抗白叶枯病,兼抗稻瘟病、纹枯病和褐稻虱。而且在年度间、不同氮肥用量及不同生育期的接菌试验结果表明,抗性稳定。经本省各地多点试种,一般每公顷产量在7500公斤以上,个别高达9900公斤,产量接近或略高于杂交稻,比常规稻增产1—2成。该品系适宜于长江中下游地区种植。
High-quality new indica rice lines 262 were highly resistant to bacterial leaf blight, blast resistance, sheath blight and brown planthopper in 1984 and 1985, respectively. And in the year, different amount of nitrogen fertilizer and different growth period of inoculation test results show that the resistance is stable. By the province more than the trial planting, the general output per hectare in more than 7500 kilograms, up to 9,900 kilograms individually, the yield close to or slightly higher than the hybrid rice, 1-2 percent increase over conventional rice. The line is suitable for planting in the middle and lower reaches of the Yangtze River.
