| description | Breeding salt-tolerant crops is necessary to reduce food insecurity. Prebreeding populations
are fundamental for uncovering tolerance alleles from wild germplasm. To obtain a physiological
interpretation of the agronomic salt tolerance and better criteria to identify candidate genes, quantitative
trait loci (QTLs) governing productivity-related traits in a population of recombinant inbred
lines (RIL) derived from S. pimpinellifolium were reanalyzed using an SNP-saturated linkage map and
clustered using QTL meta-analysis to synthesize QTL information. A total of 60 out of 85 QTLs were
grouped into 12 productivity MQTLs. Ten of them were found to overlap with other tomato yield
QTLs that were found using various mapping populations and cultivation conditions. The MQTL
compositions showed that fruit yield was genetically associated with leaf water content. Additionally,
leaf Cl− and K+ contents were related to tomato productivity under control and salinity conditions,
respectively. More than one functional candidate was frequently found, explaining most productivity
MQTLs, indicating that the co-regulation of more than one gene within those MQTLs might explain
the clustering of agronomic and physiological QTLs. Moreover, MQTL1.2, MQTL3 and MQTL6
point to the root as the main organ involved in increasing productivity under salinity through the
wild allele, suggesting that adequate rootstock/scion combinations could have a clear agronomic
advantage under salinity. |
