Agromorphological changes of Turkish tomato genetic resources according to collection years and areas

This study aimed to assess the change of agromorphological characters of tomato in Turkey along years and with respect to the initial collection area.
For that end, data recorded through the characterization of 170 tomato accessions initially collected from 60 different provinces of Turkey, between 1973 and 2011, and conserved in the Aegean Agricultural Research Institute National Gene Bank, using 30 agromorphologic traits, were investigated.
Our findings indicate that the local tomato populations of Turkey have increased in fruit size and leaf density in the last 40 years.
As the altitude increased, the number of populations with indeterminate type and small fruit sizes increased.
As the latitude and longitude grades increased, populations with smaller fruit structure were encountered.
The natural selection of producers, migrations, release of new tomato varieties, changes in the genetic structure of the populations and abandonment of these populations could be the cause of these changes.
