QTL intervals and agronomic traits revealed by QTL mapping in HL-DH and ZX-RIL populations
| Population | Trait | Chromosome | Position (cM) | Left marker | Right marker | LOD | PVE | Add | LeftCI | RightCI |
|---|---|---|---|---|---|---|---|---|---|---|
| HL-DH | PH-LS | 4D | 18.8 | AX-89421921 | AX-110564616 | 64.35 | 25.90 | 6.87 | 17.45 | 20.50 |
| ZX-RIL | SPS-HS | 5B | 92 | AX-109996563 | AX-111538681 | 5.03 | 5.23 | − 0.18 | 91.50 | 92.50 |
| ZX-RIL | SL-HS | 7A | 11 | AX-108843150 | AX-109347413 | 3.54 | 3.56 | −0.17 | 10.50 | 11.50 |
Position (cM), distance between QTL and the top marker of each linkage map; LOD, threshold of 2.5 was set for declaring the presence of QTL; PVE (%), phenotypic variation explained by QTL; Add Positive ‘additive effect’ indicated an increasing effect from Hanxuan 10 in the HL-DH population, and Zhongmai 175 in ZX-RIL population; negative ‘additive effect’ indicated an increasing effect from Lumai 14 in HL-DH population, and Xiaoyan 60 in ZX-RIL population
PH plant height, SPS spikelets per spike, SL spike length, HL-DH the DH population of “Hanxuan 10×Lumai 14”, ZX-RIL the RIL population of “Zhongmai 175×Xiaoyan 60”, LS low salinity treatment, HS high salinity treatment
