Characterization and Resistance to Bacterial Wilt Diseases (Ra/stonia so/anacearum) of 20 Eggplant (Solanum melongena L.) Genotypes

Abstract

Development of eggplant varieties resistant to bacterial wilt disease is needed to improve the productivity and quality of the eggplant. PKHT IPB have several eggplant genotypes that have the potential to be developed. To get a diversity of information sources in assembling eggplant varieties resistant to bacterial wilt disease is necessary to characterization and test of it resistance of eggplant genotypes. Research objective to obtain information about the morphological characteristics of plant genotypes are tested and to know the response its resistance to bacterial wilt (R. solanacearum). Research was conducted at trial PKHT (Center for Tropical Horticulture Studies) Pasir Kuda. The design used was a complete randomized group design one factors with three replications. Genotype 2013-070,2013-080,2013-064,2013-090 is the genotypes that are resistant to bacterial wilt disease, whereas the susceptible genotype is 2013-059, 2013-076, 20 13-043, 2013-043, 2013-049, 2013-021, 2013-046. Results of testing the qualitative characters to plant growth, stem, leaves, flowers and fruit showed the diversity. The color of fruit when it harvest of 20 genotypes tested consists of white, purple, and green. Results oftesting the plant on quantitative characters showed it di versity.
