(+) The mean value of the quantitative trait for palms having the locus was higher compared to palms not having the locus
(-) The mean value of the quantitative trait for palms having the locus was lower compared to palms not having the locus
The above analysis was possible as markers linked to the QTLs were in the pseudo-testcross configuration (type b profile, Table 2)
