Research Abstract

Quantitative trait loci (QTL) related with flowering time was identified in chromosome 1, and chromosomal segment substitution lines in this region (CCSL) were bred by backcrossing tomatoes. CCSL flowered earlier than tomato. Furthermore, homology search suggested that candidate gene for this QTL was a homolog of FLOWERING CONTROL LOCUS A of Arabidopsis.
