Abstract

Information on genetic relationships among available crop germplasm such as maize inbred lines, has important implications to breeding programs. A set of 26 maize inbreds togeher with six standard lines from CIMMYT (CML51, CML292, CML202, CML206, CML236, dan CML396), was characterized using 26 SSR markers, which were coverage of the maize genomes. The objective of this study was to analyze genetic diversities among the Indonesian maize inbred collections. Polymorphism Information Content (PIC) value and the observed genetic distance indicated the existence of large variabilities among the inbreds. Cluster analysis based on 27% of the Jaccard’s similarity coefficient placed the inbreds into three groups. Genetic distances among all the possible pairs without the standard maize lines varied from 0.32 (KSX360F2-5-1-3-1v vs KSX2601F2-5-1-1-v) to 0.88 (PT963298-1-B-B-Bv vs Mr13). Cluster and Principal Coordinate Analysis of the genetic distances, revealed a clear differentiation of the inbred lines into groups according to their source populations. This clustering were consistent with those of the known pedigree records of the inbreds based on their morphological characters. These results support the use of morphological traits in the production of maize hybrids. The SSR markers proved to be effective to characterize, identify, and demonstrate genetic similarities among the maize inbred lines.

Abstract

Plant genetic diversity is an emerging variation in a crop group caused by its genetic factors. Local corn germplasm as a source of plant genes that are able to adapt to the local environment. The purpose of this research is to obtain information on genetic variation of Tana Toraja local maize germ plasm using SSR (Simple Sequence Repeat) marker. This research was conducted at Balitsereal Molecular Biology Laboratory, Agricultural Research Agency in Maros Regency, South Sulawesi. A total of 4 local maize populations were analyzed by laboratory experimental method with observation with NTSYS pc 2.1 program. The results showed that the average number of alleles was 3.72 alleles per locus and the polymorphism rate of 0.53 with the genetic similarity coefficient was in the range of 0.47 to 0.85. 2 main clusters formed in the genetic similarity coefficient 0.47. Klaster I is Local DallePondan and Local Purple. Klaster II is Local Bebo and Kandora. The genetic distance is in the range of 0.15 to 0.74 with an average genetic distance of 0.46. From the data obtained shows that the 4th germplasm of the population of Tana Toraja Local maize diteleti has a very informative level of genetic diversity. Genetic diversity of local maize germplasm of Tana Toraja, can be used as a source of genes in the assembly of improved varieties in the future.
