Sweetpotatoes are potentially served as food, industrial raw materials, and fodder. The names of sweetpotato varieties locally in West Java are very diverse. Generally, the use of sweetpotato in West Java is to snack roasted sweetpotatoes. Consumers almost never know the name of sweetpotato varieties are consumed because of the morphological form of tuber root is almost uniform. In store sales, which form tuber root a similar actually comes from different varieties. Variability sweetpotato in West Java, other than the local varieties, as well as from sweetpotato introduced from overseas, especially Japan. In West Java, is also found wild relatives of sweetpotato, I. trifida that have roots like tuber. The research objective was to determine variability genetic potential sweetpotato traits in West Java. The study was conducted in 2009-2011. Survey and sampling the wild relatives sweetpotato have been implemented in ...

objectives of this study were to identify content of seven black soybean genotypes and to analysis stability of genotypes, widely adapted or specifically adapted. Oil content was determined using proximate analysis and observation procedure base on AOAC standard. Field experiments were conducted at ten locations across the island of Java, Indonesia i.e. Banyuwangi, Bogor, Cianjur, Cirebon, Jatinangor 1, Jatinangor 2, Madiun, Majalengka, Ngawi, and Yogyakarta. The experimental design was arranged in randomized complete block design with four replication at each environment was employed. The genotype main effect plus genotype-by-environment interaction biplots were applied to analyze and visualize pattern of the interaction component. The result elucidated that black soybean genotype that have high yield is KA 6 (2.21 t · ha–1), and potential to produce oil in amount
of 445.65 L · ha–1. GGE biplot identified that KA 6 adaptive to be cultivated in the regions of Cirebon, Madiun and Banyuwangi,
and environment similar to the three regions. The ideal environment in terms of being the most representative of the overall environments is Cianjur.

This study used 181 cassava (Manihot esculenta Crantz.) accessions from all islands in Indonesia, i.e. Java, Sumatera, Kalimantan, Sulawesi, Maluku, Nusa Tenggara Timur and Papua Islands. The study was conducted in July 2013 to March 2014. Research experiment design was arranged in Augmanted Design with three control plants per row. There were traits of morphological rod and leaf as parameter, the number of 19 traits. The analysis was using Principal Component Analysis (PCA) and Agglomerative Hierarchical Clustering (AHC). Results of this study are genetic diversity and distance cassava from Indonesia with a wide diversity level of 49.82% and from 1 to 17 genetic distance spread throughout Indonesia.
