China, is an important leafy vegetable in eastern Asia. Many traits of agronomic importance are quantitative in nature and have complex genetic basis. The identification of quantitative trait loci (QTL) represents a first step toward dissecting the
populations set fruit in 2011; no QTLs were identified successfully. Table 4. Quantitative trait loci (QTLs) for fresh-cut browning detected by interval mapping and Kruskal-Wallis in 2010 in the hybrid population of ‘Jonathan’ × ‘Golden Delicious’. Discussion
most fruit quality traits is polygenic and largely unknown ( Grandillo et al., 1999 ; Saliba-Colombani et al., 2001 ). Quantitative trait loci (QTL) analysis can be used to detect regions of the genome involved in such complex traits ( Tanksley, 1993
QTL for manually measured traits included those on paternal (MN1246) chromosome 11 and maternal (MN1264) chromosome 17 for 20 berry weight. QTL for image-derived traits did not recur between years. Table 1. Quantitative trait loci (QTL) detected at the

population ( Fig. 3 ), which shows a clear delineation between samples with the egusi seed phenotype and normal seed phenotype. Table 2. Main effect quantitative trait loci (M-QTL) and epistatic effect QTL (E-QTL) identified for seed oil as a percentage of
size to detect quantitative trait loci (QTL) has been strongly emphasized by many researchers ( Collard et al., 2005 ; Doerge et al., 1997 ; Ripol et al., 1999 ; Tanksley, 1993 ). In a polyploid crop such as sweetpotato, a large population size is

Mbp ( Liu et al., 2014 ). Using the latest estimate of Liu et al. (2014) , the average physical distance between mapped markers was calculated to be 4.67 Mbp. Fig. 4. Genetic linkage map and positions of quantitative trait loci (QTLs) associated with
