摘要
为适应南充市及长江上游水稻生产发展需要,筛选适合该地区种植的新杂交中稻组合,采用田间调查、室内考种、单收单打、随机区组设计和统计分析等方法,开展了长江上游中籼品种审定绿色通道区域试验。结果表明,综合农艺和经济性状且抗病性(尤其是抗稻瘟病)较好的品种有‘奥富优958’、‘黔丰优990’、‘六福优977’和‘广两优990’等4个,‘奥富优958’比‘F优498’(CK)增产12.97%、达极显著水平,‘黔丰优990’、‘六福优977’和‘广两优990’比CK分别增产9.24%、5.67%和4.79%,‘奥富优958’和‘黔丰优990’,是南充市国家现代农业示范区和国家农业科技园区理想的高产、优质、抗逆性强、抗病性较好的新品种。‘奥富优958’、‘黔丰优990’、‘六福优977’和‘广两优990’均可作为南充及长江上游水稻推广品种进行示范推广。
To satisfy rice production and development, and select the new hybridized rice combination which issuitable for planting in Nanchong and the upstream region of the Yangtze River, the green channel regionaltests on medium-indicar rice variety identification were conducted. The methods of field investigation, plantlaboratory test, single harvest, randomized block design and statistical analysis were used in the experiments.The results showed that four varieties（‘Aofuyou958＇, ‘Qianfengyou990＇, ‘Liufuyou977＇ and‘Guangliangyou990＇） possessed good agronomic and economical characters, as well as disease resistance（especially for rice blast resistance）. The yield of‘Aofuyou958＇increased by 12.97% compared with that of‘Fyou498＇, and the difference reached extremely significant level. Compared with that of CK, the yield of‘Qianfengyou990＇,‘Liufuyou977＇and‘Guangliangyou990＇increased by 9.24%, 5.67% and 4.79%,respectively.‘Aofuyou958＇and‘Qianfengyou990＇were the ideal varieties in Nanchong National AgriculturalScience and Technology Park, with the advantages of high yield, high quality, strong stress resistance anddisease resistance.‘Aofuyou958＇,‘Qianfengyou990＇,‘Liufuyou977＇and‘Guangliangyou990＇could be popularized as in Nanchong and the upstream region of the Yangtze River.
