Abstract

Eggplant (Solanum sp.) is one of the most important solanaceous vegetable crop plants. Root-knot nematode (Meloidogyne incognita-RN) is one of the biotic factors and becoming a serious problem, affecting the root system and physiological activities, resulting in reduced plant growth and yield of eggplant. This study aims to evaluate morphological response of 24 eggplant accessions from Gene Bank of PIAT UGM collection to nematode infection at the nursery phase and to determine the diversity between solanaceae accessions from different regions. Collection and characterization of genetic resources and local cultivars are required for the improvement of new varieties. The response of morphological plants is done by looking at the morphology condition of plant and susceptible index value due to nematode infection. SL- TE 42 and SL-TE 28 had the highest average susceptible index, namely 2.15 and 2.45. Accessions SL-TE 590 (S. aculeatissimum), SL-TE 74 (S. aculeatissimum), and SL-TE 589 (S. torvum) had the lowest susceptible index values, namely 0.37; 0.36, and 0.79. PCoA analysis differentiated accessions in to four main clusters with wild type cultivars (SL-TE 74, SL-TE 589, and SL-TE590) grouped in cluster I and local cultivars in cluster II, III, and IV. Accessions SL- TE 74, SL-TE 589, and SL-TE590 showed the highest percentage of polymorphic loci, respectively, 17.57%, 20.95%, and 20.95%. The results revealed that there were 68% of the total genetic diversity within the population, and 32% among population.
