Phenotypic analyses of wheat accessions for eight plant architecture traits. a Overview of the eight traits in wheat. The shortest and longest tillers were selected from fertile tillers with spikes. The length of the main shoot as the length of the strongest tiller. The difference between the length of the shortest and longest tillers (longest-shortest tiller) was calculated for each plant. b Distribution of phenotypic values and broad sense heritability of the eight plant architecture traits. The broad sense heritability was estimated from the repeatability between raw phenotypes. c Pearson’s correlation coefficients were calculated using the phenotypic values for the 306 worldwide wheat accessions
