Introduction to the Beidao No. 1 rice variety and key cultivation techniques

Japonica rice, bred by the Suihua City Northern Rice Research Institute. In the 1997-1998 regional trial, the average yield was 8311.0 kg/hm2, an average increase of 8.0% over the control Dongnong 416; in the 1999 production trial, the average yield was 7691.8 kg/hm2, an average increase of 9.1% over the control Dongnong 416. The growth period is 131 days, requiring an active accumulated temperature of 2506.8°C. Plant height is 89 cm, panicle length is 17.4 cm, 101 grains per panicle, and 1000-grain weight is 26 g. Medium tillering ability, strong stems and resistant to lodging, favors fertilizer and water, and cold-tolerant at the seedling stage. In 1998, artificial inoculation showed seedling blast grade 8, leaf blast grade 3, and neck blast grade 9; natural infection showed seedling blast grade 9, leaf blast grade 3, and neck blast grade 7. Grain quality meets the national first- and second-class high-quality rice standards.
