Keragaan In Vitro dan In Vivo Hibrida Somatik antara Solanum melongena cv. Dourga dengan Solanum torvum Sw.

Abstract

Eggplant is the plant which susceptible to several diseases. One attempt to improve these caracters is combining the eggplant cultivar with its wild relatives through protoplast fusion. The research was conducted to study the variability in vitro and in vivo of somatic hybrids between Solanum melongena cv. Dourga with Solanum torvum Sw. This study used seven clones, Solanum melongena cv. Dourga, Solanum torvum Sw., and 5 clones of somatic hybrids (SMST1, SMST2, SMST3, SMST4, and SMST5) was arranged with completely randomized design single factor. The variables measured were plant height, number of leaves, leaf length, petiole length, number of roots, root length, number of stem segment, stem color, petiole color, the number of spines on the leaf surface, and leaf blade lobing. In in vitro conditions, the growth of Solanum torvum Sw. significantly different with the five somatic hybrid clones, with higher vigor. Clones SMST1, SMST2, and SMST4 showed better growth than clone SMST3 and SMST5. In in vivo condition, the clones tested had a similarity with Solanum torvum Sw.
