ABSTRACT

Ninety-two accessions of eggplant (Solanum melongena L.) complex and 19 accessions of other Solanum species collected from various localities in Malaysia and other countries were grown for assessment of their morpho-agronomic characters. Useful features such as days to germinate, days to first flowering and days to first harvest, fruit shape, size, and colour, prickleness and susceptibility to bacterial wilt were found to be highly variable. This study showed that Solanum torvum was the most resistant against bacterial wilt disease, with other Solanum species ranging from moderately resistant to highly susceptible.


ABSTRAK

Sembilan puluh dua aksesi kompleks terong (Solanum melongena L.) dan 19 aksesi spesies Solanum lain yang dikutip dari berbagai tempat di Malaysia dan negara-negara lain telah ditanam untuk menilai ciri-ciri morfo-agronominya. Sifat-sifat yang berguna seperti bilangan hari untuk bercambah, bilangan had mula berbunga, bilangan hari mula mengeluarkan hasil, bentuk, saiz, dan warna buah, kehadiran duri dan ketahanan terhadap layu bakteria adalah sangat variabel. Kajian ini juga menunjukkan bahawa S. torvum paling resistan terhadap penyakit layu bakteria manakala spesies-spesies lain berada antara sederhana resistan dengan paling tidak resistan.

Key words: Bacterial wilt, morphology, Solanum melongena L., variability.
