Genomic regions associated with important seed quality traits in food-grade soybeans

BMC Plant Biology

Table 2 Putative QTL for additional food-grade traits of interest (seed yield, seed weight and sucrose concentration) associated with major seed protein concentration QTL identified by multiple QTL mapping (MQM) in a RIL population derived from ‘AC X790P x S18-R6’ and ‘AC X790P x S23-T5’ examined under combined Ontario environments from 2015 and 2016

^aQTL for the same trait detected in all individual environments (CHA15, CHA16, MER15, MER16 and PAL16) and the combined environment (GMET) with the same or overlapping marker interval was designated as one QTL
^bLOD thresholds were calculated through a permutation test with 1000 iterations and a Type I error rate of 0.001
^cAdditive effects calculated as the absolute value of half the subtraction of the mean of genotypes with the ‘S18-R6’ (‘POPn_1’) or ‘S23-T5’ (POPn_2) allele (negative effect) from the mean of genotypes with the ‘AC X790P’ allele (positive allele)
