A few supplemental collections were made in the vicinity of Tapachula, Chiapas. A grand total of 183Cucurbita collections was made, distributed as follows:C. pepo-49;C. moschata-47;C. mixta- 41;C. ficifolia-11;C. foetidissima-13;Cucurbita sp. wild, unidentified- 22. A few collections were made in the following genera:Sechium-4;Lagenaria-2;Sicana-1;Momordica-4;Sicyos-2;Cucumis melo-2;C. anguria-1. The ecological distribution of the 4 cultivated species is reported and discussed. Seed of these materials was divided equally between the participating countries, and will be made available to interested plant breeders. |
