Abstract

We have assembled a tomato core collection composed of ~7000 domesticated (S. lycoperiscum) lines, along with representative wild species. This germplasm was generously provided by different international sources and are covered by Material Transfer Agreements (MTA).

In the summer of 2007, the EU-SOL Core Collection (~2 plants per genotype) was planted in Akko, Israel using the agronomic technique of metal staking to facilitate phenotyping and the handling of indeterminate plants. Early in the growing season, the plants were exposed to herbicide, but by the end of the season, the population largely recovered allowing for phenotyping of key descriptors. Most of the collection will be grown and phenotyped again in 2008 in Israel (best phenotyping window from the middle to the end of July).

The EU-SOL Core Collection is amenable for searching according to a phenotypic catalog of key descriptors and combinations of these traits. The phenotypes were determined visually with a focus of qualitative traits usually determined by a single gene:

  • Fruit fasciations - (Fascinated or not).
  • Fruit cracking - (Cracking or not).
  • Plant habit - (Determinate or indeterminant).
  • Leaf shape - (Regular, potato leaf or other).
  • Inflorescence structure - (Regular, compound, forked).
  • Uniform ripening - (Uniform or green shoulders).
  • Fruit color - (Red, orange, yellow, peach, pink, green, dark red)
  • Fruit size - (pimp, cherry, cocktail, processing, cluster, large, very large)
  • Fruit shape - (Round, flat, ovate, block, heart, flattened, cylindrical, pear)
  • Fruit epidermis (Transparent or Yellow)
  • Leaf veins (Green or Transparent)

If you are interested in obtaining seed please email a list of lines + codes, and we will send you the appropriate paperwork. Please note that seed increase was not done last year so when you grow the plants we need to collect seed + phenotypes.
