Introgression of TaSPL17-A favorable alleles in recombinant inbred lines (RILs) and near-isogenic lines (NILs) improves spike traits. Mean spike length, spikelet number, grain number per spikelet, grain width, grain length, and TGW are shown for original Jingshuang16 (RILTaSPL17−A−L first row [a-f], NILTaSPL17−A−L second row [g-l]) and improved Jingshuang16 (RILTaSPL17−A−H first row [a-f], NILTaSPL17−A.−H second row [g–l]). Data are shown as means ± SD. Significant differences were determined by Student’s t test (two sided, *P < 0.05, **P < 0.01, ***P < 0.001)
