aEight genotypes were designated by three-letter combinations of W or C in genotypic order at qAWNL2, An-1 and LABA1, where W and C indicate wild and cultivated homozygous alleles, respectively
bLength reduction compared to W630
cOverall averages given with different letters are significantly different among the eight genotypes and two parental lines (Tukey’s test, P < 0.05)
