| Project of hybrid rice seed production of Rice Department has been conducted in 8 main topic studies which were (1) panicle development of A lines and R lines for their synchronization in hybrid rice seed production, (2) A lines seed multiplication development, (3) B, and R lines seed multiplication development (4) F1 hybrid seed multiplication development (5) the suitable harvest time for F1 seed production, (6) storability of F1 seed and their parent, (7) economic cost, and (8) technology transfer for hybrid rice seed production. These experiments were carried on in Pathumthani Rice Research Center, Phitsanulok Rice Research Center, Suphanburi Rice Research Center, Prachinburi Rice Research Center in 2006-2013 in order to increase efficiency of hybrid... |
