Melon (Cucumis melo L.), one of the most important fruit crop species, is cultivated worldwide. In this study, a total of 206 melon accessions conserved at the National Agrobiodiversity Center (NAC) in RDA were characterized for nine morphological characteristics according to the NAC descriptor list. In addition, to confirm the genetic composition of each melon accession, genetic profiling was performed using 20 SSR markers. Among the 206 melon accessions, 159 (77.2%) were collected from Asia. The color of fruit flesh and skin were mostly 'white' (56.0%) and 'green' (49%), respectively. Days to female flowering (FD) and maturity (MD) of the accessions ranged from 58 to 72 and 17 to 63, respectively. The fruit length and width of the accessions ranged from 6.0 to 29.3 and 3.6 to 17.2 cm, respectively. The sugar content (SU) ranged from 2.5% to 13.2% with an average of 7.0%. In correlation analysis, SU showed positive and negative correlations with MD and FD, respectively. The accessions were classified into four clusters by cluster analysis. From the results of genetic profiling using 20 SSR markers, three accessions (K189118, K100486, and K190292) were expected to be inbred lines among 206 melon accessions. These results could expand the knowledge of the melon germplasm, providing valuable material for the development of new melon varieties to suit consumer tastes.

To compare agronomic and seed traits of 135 common bean landraces originating from Korea, Bulgaria, and El Salvador, we evaluated 20 morphological traits and performed principal component analysis (PCA). In the PCA, the first and second principal components accounted for 55.15% and 15.97% of the total variance, respectively. The first component showed a strong positive correlation with seed size and 100-seed weight, whereas the second component produced a strong negative correlation with days to flowering and days to maturity, indicating that these traits may explain the differences between landraces originating from different countries. Landraces from Korea showed higher variation in days to flowering and days to maturity; those from Bulgaria produced larger and heavier seeds; those from El Salvador produced smaller and lighter seeds and flowering and maturity occurred earlier. In addition, the landraces from El Salvador had relatively lower diversity compared to those from other countries, as they were grouped within a small cluster in the PCA. These evaluation results may provide important information for selecting breeding materials, and diversity analyses of landraces from different countries provide information for securing genetic resources.
