| Abstract | Rice breeding for high yield potential by using introduced variety. Crossing between introduced variety and Thai improved variety were development methodology for a new line with high yield potential and well adaptation to Thailand's condition. This experimentwas usedCH1 variety, which rice introduced from China, crossed with RD49 Thai rice variety. Three populations were contained the genetic of CH1 variety with 50%, 75% and 87.5%. Plant type and grain weight were used for line selection. The results showed thatthree populations including F5, BC1F5and BC2F5progenies were high yield potential. Moreover, the selected lines showed outstanding performance. F5-8-9-2line was large flag leaf, flag leaf length 41.33 centimeter.BC1F5-80-9-3 was high number of panicle per plant, 12.13 panicles. BC2F5-90-9-10 was high number of filled grains per panicle, 227.80 grains. Outstanding Characteristics of these three lines were related to source and sink that had the main effect on yield. |
