Pearson’s correlation coefficient between phenotypic traits using best linear unbiased estimates (Experiment II). FE, fruiting efficiency in grains g−1 of spike dry weight at anthesis + 7 days; GPI, glume partitioning index; LmPI, lemma Partitioning index; API, awn partitioning index; PPI, palea partitioning index; FPI, floret partitioning index; RPI, rachis partitioning index. E2_C18, E2_C19, E2_Q18, E2_Combined refers to Citra 2018, Citra 2019, Quincy 2018 and combined dataset respectively for the experiment II
