Abstract

Intraspecific and interspecific relationship between Solanum melongena cv. Dorli, Round Black and S. surattense was investigated. Chromosome association and pollen sterility were also calculated for the parent and hybrids. The hybrid Dorli×surattense was possible only when the former was female parent. The fruits were obtained when the crosses were attempted between Round Black×Dorli but with sterile seeds. Some of these hybrids did not survive up to the flowering age. Round Black×surattense was unsuccessful in either direction. Cytological studies showed univalents frequently at diakinesis and metaphase I in the hybrid plants but not so in their parents. The univalents were due to the absence of pairing between homologous chromosomes. Laggards varying from 2 to 4 and bridges were observed in the hybrid plants.
