Abstract

QTL analysis of 16 morphological/developmental traits is reported for the Landsberg erecta×Cape Verde islands (Ler × Cvi) population of RILs, together with their genotypes for 16 SSR markers. A total of 43 QTL were found across all 5 chromosomes for the 16 traits analyzed; 8 QTL that control height, 19 QTL for leaf characters and 16 QTL for flowering characters. These QTL form six distinct clusters spread across chromosomes 1–4, while chromosome 5 has QTL along its length. We have confirmed four QTL identified by others, revealed several new QTL affecting flowering and height traits and demonstrated epistasis for several traits. We have identified several possible candidate genes for these QTL, some of which are potentially relevant to plant breeding aims.
