The selection of Bijing 37 (B37) is the result of a comprehensive application of many advanced breeding technologies including: multiple Indica Japonica crosses, population screening, synchronous multiple site yield trials, and directed selection. The yield of B37 has reached at advanced domestic and international level and the major physiological and biochemical indicators have reached at the standard of the Ministry issued first class Japonica rice for human consumption. The commercial use of B37 has brought along significant socio economic and ecological benefit. From 1994 to 1999, the total planting area of B37 at Bijie Prefecture and Liupanshui Municipality was 40979.1hm2. The newly increased general rice output was 25, 104.165 ton, the newly increased general production value was 35,145,831 Yuan, and the newly increased net profit was 33,809,396 Yuan. The profit rate of technology investment was 25.3, the profit rate of research investment was 135.24 and the profit rate of extension investment was 78.02. The profit rate of the newly increased production fee was 9.17. Through demonstration and extension, the rice cultural level and the scientific value of the Japonica rice area in north western Guizhou Province have been significantly improved.
