Hdd, heading date; Cl, culm length; Pl, panicle length; Nt, number of tillers; Tgw, 1000 grain weight; Cc, content of chlorophyll. ^z Interval markers are those within the significance threshold on each border of the QTL range. ^y The proportion of evaluated phenotype variations attributable to a particular QTL was estimated using the coefficient of determination (r²). ^x Positive values of the additive effect indicate that alleles from Samgang are in the direction of increases in the traits. ^w Increased allele is the source of the allele causing an increase in the measured trait.
