Production of interspecific tomato crosses between cultivated tomato and selected wild relatives

(A pre-breeding research programe to develop high quality tomato

variety/ies)

worldveg.org ➢ Problem Justification 10 of x

➢ Tomato (Solanum lycopersicon) is one of the major vegetable crops in Sri Lanka in a area of around 8000 ha/year.

➢ Consumed by all social strata & all ethnic groups ➢ Rich source in vitamins, minerals & anti oxidants ➢More than 90% of the seed requirement is supplied from imported seed ➢ Bacterial wilt, virus complex, bacterial canker, high temperature/heat stress are

major constraints at present.

➢ Need extensive research to develop high yielding new varieties with

resistance/tolerance to one or more above constraints

 Produce pre breeding materials which can be used to

develop new tomato varieties with bacterial wilt resistance and other desirable quality characteristics
