Abstract EN
We have identified an accession (LA2093) within the tomato wild species Solanum pimpinellifolium with many desirable characteristics, including biotic and abiotic stress tolerance and good fruit quality.
To utilize the full genetic potential of LA2093 in tomato breeding, we have developed a linkage map based on an F2 population of a cross between LA2093 and a tomato breeding line, using 115 RFLP, 94 EST, and 41 RGA markers.
The map spanned 1002.4 cM of the 12 tomato chromosomes with an average marker distance of 4.0 cM.
The length of the map and linear order of the markers were in good agreement with the published maps of tomato.
The ESTs were chosen based on their sequence similarities with known resistance or defense-response genes, signal-transduction factors, transcriptional regulators, and genes encoding pathogenesis-related proteins.
Locations of several ESTs and RGAs coincided with locations of several known tomato resistance genes and quantitative resistance loci (QRLs), suggesting that candidate-gene approach may be effective in identifying and mapping new R genes.
This map will be useful for marker-assisted exploitation of desirable traits in LA2093 and other S.
pimpinellifolium accessions, and possibly for utilization of genetic variation within S.
lycopersicum.
