Diversity and similarity of melon (Cucumis melo L.) groups and determination of distinguishing morphological characters

Abstract. Saputra HE, Syukur M, Suwarno WB, Sobir. 2022. Diversity and similarity of melon (Cucumis melo L.) groups determination distinguishing morphological characters. Biodiversitas 23: 6254-6261. Characterization is an important activity for the study genotype diversity similarity. The was aiming at obtaining information about to determine characters as differentiators between groups. genotypes tested were IPB240, IPB283, IPBM21, IPBM23, IPBME5, IPBMETA9, UME20, UME38, UME39, UME90, UME91, UME98, UME99, UME100, UME101. based on UPOV IPGRI guidelines qualitative quantitative Two showed no variation in all genotypes, namely sex expression (EK) secondary skin color outside groove (WKSDA). Qualitative that have high (WA), maximum width grooves (LMAA), intensity (IWA), flower stalk thickness (KTBN). UME98 had most different appearance from other heatmap. depth fruit are characteristics genotypes. There differences inodorus reticulatus types. Unlike IPBMETA9 genotype, UME101, UME38 formed same clusters with makuwa group. Melon group type depth, ratio length diameter, diameter hermaphrodite stalks, thickness. similarities, making it difficult find specific observed.
