Summary Pod dehiscence facilitates seed dispersal in wild legumes but results yield loss cultivated legumes. The evolutionary genetics of the legume pod trait remain largely elusive. We characterized chromosome segment substitution lines Glycine max crossed with soja and found that gene underlying predominant quantitative locus (QTL) soybean pod‐shattering was 1 ( Pdh1 ). A few rare loss‐of‐function (LoF) alleles were identified G . , while only an allele featuring a premature stop codon selected for indehiscence spread to low‐precipitation regions increased frequency. Moreover, correlated interactions among 's haplotype, expression, environmental changes developmental plasticity revealed orthologous genes specifically originated warm‐season their LoF then parallel‐selected during domestication crops. Our provide insights into convergent evolution legumes, facilitate understanding intricate between genetic robustness adaptation plasticity, guide breeding new varieties indehiscence.
