FT, flowering time; SL, length until first silique; TL, total plant length; IB, main inflorescence branch number; BB, basal branch number; TB, total branch number.
Chromosome number.
2-LOD support interval.
Percentage of total variation explained by individual QTL.
Effect of QTL calculated as μB − μA, where A and B are RILs carrying Ler and Cvi genotypes at the QTL position, respectively. μB and μA were estimated by MapQTL. Effects are given in days (flowering time), centimeters (length at first silique and total length), or numbers (elongated axils, basal branch number, and total branch number).
Percentage of total variance explained by genetic factors estimated by MapQTL.
Percentage of total variation explained by interaction between individual QTL.
QTL showing significant epistatic interactions (P < 0.05) and used to estimate the percentage of explained variance by genetic interactions.
