Penyebaran ubi kayu banyak tumbuh di wilayah negara tropis, terutama di Afrika, Asia, dan Amerika Latin. Ubi kayu asal Indonesia salah satu kekayaan plasma nutfah yang berpotensi untuk dikembangkan terutama kandungan patinya. Asal wilayah ubi kayu yang beragam dari Aceh sampai Papua merupakan jarak alami dari wilayah geografis Indonesia yang luas. Hal ini berdampak pada perbedaan keragaman dan jarak genetik ubi kayu yang berpotensi sebagai bahan pangan, industri dan biofuel. Secara global permintaan ubi kayu dalam bentuk produk lain semakin bertambah terutama dalam bentuk tepung dan pati. Kandungan pati ubi kayu yang tinggi yaitu 30% pada umbi segar atau 80% dalam bentuk produk kering (tepung) menjadi salah satu faktor pemanfaatan ubi kayu. Kandungan pati inilah yang berpotensi sebagai bahan pangan, industri dan komoditas utama penghasil BBN (Bahan Bakar Nabati) atau lebih tepat sebagai penghasil FGE atau Fuel Grade Ethanol .

Fourty six new mutant lines used in maize breeding programs in Indonesia, were crossed to three tester lines in a lines x testers mating design. The 138 F1 hybrids, the 46 parental lines and 3 tester lines were evaluated at Arjasari, West Java, Indonesia for the following objectives: (i) to analyse line x tester data for maturity and grain yield using GGE for identifying genetic interrelationships among parents; and (ii) to identify the best combinations for maturity and grain yield in maize hybrids. The GGE biplot graphic allowed a rapid and effective overview of general combining ability (GCA) and specific combining ability (SCA) effects of the inbred lines, best lines and tester, as well as their performance in crosses. High GCA effect for maturity and grain yield was determined based on Average Tester Coordination function of GGE biplot. Thus, it was revealed that DR 4 is the best tester for early maturity and DR 6 for grain yield. The maximum best- parent heterosis values and the highest SCA effects resulted from mutants (10, 31, 32, 34, 36, 48) and mutants (5, 7, 10,32, 34, 36, 37 and 48 ) crosses to testers (4, 6 and 8) for early maturity and grain yield respectively, This is potentially useful in maize breeding programs to obtain high-yielding hybrids in areas with the same climate of Indonesia.

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.

Merr.) seed is potential as an alternative renewable energy source. The 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.
