| Abstract: | Based on a RFLP map with 89 marker loei constructed from an F2 population, QTLs for plant height and its components have been identified and mapped. Thirty two QTLs were detected, 7 for plant height (PH), 3 for the length of panicle (LP), 2 for the length of first internode (LFN) , 3, each for the length of second internode (LSN) and the length of third internode (LTN) , 6 for the length of fourth internode (LFON) , 4 each for the No. of internode (NON) and the dry weigth of the first internode (DWFN). Seven QTLs for PH were located on chromosome l, 2, 3, 4, 5, 8 and 12 respectively that collectively contributed 79% of the ob-served phenotypic variation. In addition, the % variation explained, additive effects and domi-nance effects for all QTLs detected were analyzed. |
