National Rice Industry System Nanjing Comprehensive Experiment Station (NCES) held its 2011 annual meeting in Nanjing on December 14, 2011. The meeting aimed to review the new rice varieties and techniques and their extension in 2011. Director Deng Jianping of Crop Cultivation Station of Jiangsu Agriculture Commission was invited to the meeting. More than 30 technical backbones from NCES, demo counties and relevant research institutions attended the meeting.
The meeting was chaired by NCES Director Wang Cailin. Representatives from demo counties including Gaoyou, Jiangyan, Hai’an, Zhangjiagang and Wuxi made 2011 work reports in new rice varieties, demonstration and extension of new techniques, technical services and training. They also exchanged their work experiences and presented work plans for 2012. Director Wang Cailin made summary speeches and presented awards to outstanding individuals and groups. In 2011, NCES has carried out experiments and demonstrations in Nanjing and 5 other demo counties, with 174 new varieties (combinations), 68 demo varieties and 26 demo fields for different sizes. With the support of local authorities, NCES has provided more than 30 trainings for 4,600 farmers in the demo counties, with a distribution of 25,000 brochures. The selected new japonica rice variety with good taste and early maturity Nanjing 5055 passed provincial approval; japonica rice variety 95You161 passed national evaluation; and new middle japonica rice variety Ning 9108 is in provincial trials. The selected 16 new varieties (combinations) will go through regional trials and preparatory trials of provincial and national level in 2012.
Great progress has also been made in new variety demonstration. The average yield per mu of Nanjing 46 reached 655.3 kg, 9.8% higher than local average; the average yield per mu of Nanjing 5055 reached 755.6 kg, 22.9% higher than local average, with the highest yield of 780 kg; and the average yield per mu of Nanjing 44 reached 741.6 kg, 20.6% higher than local average, with the highest yield of 775.2 kg. Despite the shortage of rainfall in early spring and low temperature in September and October, the rice grain yield was increased thanks to the integration and demonstration of new varieties and techniques.
The year 2011 is another year of grain increase. For example, the average rice yield in Gaoyou reaches 588.7 kg, 46.83 kg higher than last year (an 8.64% increase); the average rice yield in Hai’an reaches 646 kg, 13.2 kg higher than last year (a 2.1% increase, record-breaking); and the average rice yield in the 5 demo counties are 15.6 kg higher than last year (a 2.8% increase, record-breaking).
In the end, Director Wang Cailin made a detailed work arrangement for 2012 and held trainings for the technical backbones from 5 demo counties.
