QTLs for plant height and its components on the substituted segments of fifty-two single segment substitution lines (SSSLs) in rice were identified through t-test (P≤0.001) for comparison between each SSSL and recipient parent Huajingxian 74. On the 14 substituted segments, 24 QTLs were detected, 10 for plant height, 2 for panicle length, 4 for length of the first internode from the top, 5 for length of the second internode from the top and 3 for length of the third internode from the top, respectively. All these QTLs were distributed on nine rice chromosomes except chromosomes 5, 9 and 11. The additive effect ranged from –4.08 to 3.98 cm, and the additive effect percentages varied from –19.35% to 10.43%.
