Chr, chromosome; DM, distance between markers; ρ, Spearman rank correlation coefficient; IGM, individual genetic maps used for the consensus map construction. Physical map was obtained from the reference map B73 RefGen_v2. Consistent proportion is the proportion of markers arranged in the same order with those on the corresponding chromosomes of the physical map.
