THESIS

CONCLUSION
On the basis of finding from the present studies, the following conclusions can
be drawn:
1. The morphological characterization of the 89 accessions of Solanum spp.
collected from Southeast Asia have been done using a standard set of IBPGR, they
were identified follows:
1) Solanum melongena L. (38 accessions)
2) S. aculeatissimum (2 accessions)
3) S. aethiopicum (1 accession)
4) S. ferox (17 accessions)
5) S. indicum (8 accessions)
6) S. mammosum (1 accession)
7) S. sanitwongsei (1 accession)
8) S. torvum (11 accessions)
9) S. trilobatum (3 accessions)
10) S. viarum (1 accession)
11) S. xanthocarpum (6 accessions)
2. The S. melongena is the major group among 89 accessions of Solanum spp.
originally collected in Southeast Asia.

3. The result of cluster analysis based on quantitative traits had more variation
than qualitative traits. Howevr, both analyses gave almost the same members in each
cluster. The variation among the eleven Solanum spp. can be attributed to their
inherent variation and geographic distribution.
4. Based on success rate of crossing among species, S. torvum is more closely
related to S. melongena than the other three species (S. americanum, S. villosum and
