^aEnvironment are E1: Mian’yang in 2015–2016, E2: Mian’yang in 2016–2017, E3: combined environment over the 2 years.
^bNumber of unconditional QTL for grain yield.
^cStage for photosynthesis traits are S: seedling stage, H: heading stage.
^dNumber of conditional QTL. The first Arabic numerals before the ‘‘ + ’’ indicate the number of QTL detected in both unconditional and conditional analyses with equal phenotypic variation (phenotypic variation of conditional QTL ranged less than 10% of that of the corresponding unconditional QTL); the middle Arabic numerals indicate the number of QTL detected in both unconditional and conditional analyses with reduced or enhanced phenotypic variation; the third Arabic numerals following a ‘‘ + ’’ indicate the number of QTL that was detected only in conditional analysis.
