Abstract

Mungbean varieties were mainly characterized based on morphological traits. Molecular genetic approach is expected to help the breeder in identification of mungbean varieties in more detail and to protect intellectual property right. This study aimed to identify Indonesian mungbean varieties based on DNA fingerprint profile using a marker set to support morphological characters. A total of 22 Indonesian mungbean accessions were characterized based on 21 morphological traits and 55 simple sequence repeats (SSRs) primers. Of the total 22 mungbean varieties used in the present study, 16 varieties were improved varieties and remaining six varieties were local varieties originated from Java, Nusa Tenggara and Sulawesi collected in GeneBank of ICABIOGRAD. The results showed that the 21 morphological characters were not sufficient to differentiate 22 mungbean varieties, while SSR analysis revealed that eight multi-alleles markers and high polymorphic information content (PIC) values have been successfully selected for varietal identification. The selected markers enabled to differentiate each mungbean variety according to their genetic marker with the lowest distance of 0.125, demonstrating the robustness of the selected marker set as a tool to identify a specific DNA fingerprint profile as a varietal identity (ID). The genetic identity of a variety was shown by digital barcoding which represented a series of alleles produced by corresponding markers. The DNA fingerprint profile of each variety would be beneficial as reference identities of a mungbean variety.

Abstract

Variation within bulb tunics has been used to determine the genetic diversity in Allium species, including shallots. However, no such study has been reported for shallots of Indonesia. The study aimed to analyze the genetic diversity of the Indonesian shallots based on the bulb-tunic patterns. Thirty-five shallot genotypes from main production centers in Indonesia were used. The ultrasculptures of the bulb tunics were examined by light microscopy, including the inner surface and cell shape patterns of the bulb tunics. The phenotypic data, i.e. quantitative and qualitative traits were subjected to the descriptive statistics, principal component, correlation, regression, and clustering analyses. The results showed that the bulb-tunic cell patterns were varied, which shared almost identical with 13 Allium species. Total bulb weight per genotype showed the greatest variation (cv = 89.10%) and significant correlation with bulb weight per plant (r = 0.773). The principle component analyses showed the cumulative proportion of 78% of the total morphological variation in all shallot genotypes. Based on clustering analysis, the genetic variation of Indonesian shallots are grouped into twelve clusters with 50% genetic similarity. The study indicates that Indonesian shallots are genetically varied and could be useful for further utilization in their genetic improvement program.
