  • QTLs are named according to trait abbreviations. The first number following each abbreviation indicates the chromosome number, and the second number distinguishes the QTL mapping to the same chromosome and affecting the same trait (e.g., fw11.1). For QTL that were significant for more than one adjacent marker, the two flanking markers are given with the most significant marker underlined. Sources: LEG, L. esculentum; PM, L. pimpinellifolium. % PVE (R2), percentage phenotypic variation explained; N, number of plants; mean 5 average phenotypic value for plants with the following genotypes: AA, homozygous esculentum; Aa, heterozygous; aa, homozygous pimpinellifolium; d/a, gene action for each QTL.
