QTLs of flowering time in A2 and C6 linkage groups of B. napus. Light blue boxes represent E segments of Arabidopsis chromosome 1. Black lines indicate the confidence interval of flowering time QTL estimated from different environments. (A) A QTL cluster located in C6 (designated as qcFT.C6). An inverted duplication corresponding to E segments of Arabidopsis chromosome 1 was located in the cluster region. The two red arrowheads indicate the position of BnC6.FT.a and BnC6.FT.b. QTL detected from the two winter-cropped environments in A2 linkage group and red arrowhead indicates the position of the locus BnA2.FT.(B) Two NILs (BC4F4) with Tapidor introgressions in qcFT.C6 region and NY7 as control grown in Gansu (spring-cropped environment). Red boxes represent known homozygous Tapidor introgressions, blue boxes represent homozygous recurrent parent (NY7). An average of 10 individuals per line was analyzed.
