Determination of grain yields of stable and high-yielding maize hybrids in a wide environment requires high accuracy. Many stability measurement methods have been used in multi-environment experiments. However, the relationships among the different methods are still difficult to understand. The objectives of this study were to 1. Identify the effect of growing season and location (Environments = E), hybrids (Genotypes = G), and their interactions (GEIs) on grain yields; 2. Select high-yielding and stable maize hybrids in a wide range of environments; 3. Determine the relationship between each stability estimation; and 4. Determine the mega-environment of maize hybrid and identify the best locations for testing. Field experiments were conducted at ten locations in Java Island, Indonesia, for two growing seasons using a randomized completed block design with three replications. The experimental results showed that the main effects of the growing season, location, hybrid, and GEIs, significantly affected maize hybrid yields. Stability estimations of TOP, S⁽³⁾, S⁽⁶⁾, NP⁽²⁾, NP⁽³⁾, KR, NP⁽⁴⁾, CV_i, and b_i, belong to the concept of dynamic stability that can be used to select maize hybrids in favorable environments, while other estimations were classified as in the static stability. Three maize hybrids were successfully selected, with high and stable yields based on numerical and visual stability estimations, namely SC2, SC7, and SC9. The three hybrids can be used as candidates for sustainable maize development programs. The dry season, the rainy season, and the combination of two growing seasons produced three mega-environments. GJRS and KARS were the most discriminative environments. Both environments can be used as favorable environments for selecting the ideal maize hybrid.

Multi-trait selection is very helpful in plant breeding programs. This technique can select genotypes for specific traits. Yield performance of maize hybrids is influenced by genotype-by-environment interactions (GEIs). This requires multi-environmental testing to identify superior hybrids. The aims of this study were to: (1) select maize hybrids within favorable traits such as grain yield and yield attributes; (2) identify genotype and environment interactions (GEIs) within maize yield; (3) evaluate maize hybrids adaptability to four different locations in West Java; and (4) identify a representative environment for testing and developing new maize hybrids. Twenty-two maize hybrids were evaluated using a randomized block design repeated three times in each environment. The genotype by traits (GT) biplot showed that G3 maize hybrid was superior to ear weight (EW), ear weight without corn husk (EwoH), ear weight per plot (EWP), plant height (PH), ear diameter (ED), and 1000 seed weight (OSW) traits. The G22 maize hybrid was superior to ear weight without corn husk per plot (EwoP), ratio seed weight and ear weight without corn husk (RSEW), grain yield per ha (Y), seed weight (SW), and seed weight per plot (SWP) traits. Combined analysis of variance showed that genotype (G), environment (E), and their interactions (GEIs) had a significant effect on yield (p < 0.01) with contributions of 85.63%, 2.24%, and 12.13%, respectively. The combined stability measurement results and the GGE biplot reveal that G2 is a stable high-yield hybrid, while G4 and G16 are unstable high-yield hybrids. The most representative environment is Arjasari, with the sole-cropping system (ARJ M). This study reveals that the resulting maize hybrid can be useful as a substitute for commercial hybrids currently used. The stable high yield of maize hybrids can be recommended as new varieties with wide adaptation, while unstable high-yield hybrids can be recommended as varieties adapted to specific environments.

Bananas are one of Indonesia’s most important horticultural crops, valued for their adaptability and economic potential. Among them, the Roid banana (ABB) (Musa spp.) stands out as a local variety native to West Java-Indonesia, particularly the Jatigede District, Sumedang Regency where it thrives naturally without agronomic inputs. Known for its resistance to pests and diseases, long shelf life, and strong fruit attachment that reduces post-harvest losses, the Roid banana remains underutilized and understudied. Despite its advantages, research on its genetic diversity is limited, highlighting the need for characterization as a foundation for conservation and breeding. This study, conducted from October to December 2023 in the Jatigede District, aimed to analyze the distribution patterns and genetic diversity of Roid bananas. Characterization used a survey method and purposive sampling in situ. Results revealed two primary clusters dominated by accessions from Ciranggem and Jemah Villages. Key traits supported clusters were peduncle curvature, bunch length and density, number of fruit hands, male flower attitude, apex shape, skin color, plant height, and the presence of hermaphrodite flowers. The genetic diversity based on Euclidean distances was 0.47 to 11.92. The Index of Cultural Significance value was 105, implying a very high level of utilization diversity. These findings highlight the genetic richness and cultural importance of Roid bananas, offering valuable insights for future conservation and breeding programs. Keywords: characterization; cluster analysis; exploration; Index Cultural Significance (ICS); Musa spp.

Penelitian ini bertujuan untuk mengeksplorasi dan mengembangkan produk makanan lokal berdasarkan keragaman sumber daya makanan lokal di Jatinangor, Sumedang, Indonesia. Wilayah ini memiliki beragam bahan makanan lokal, namun upaya yang dilakukan untuk memanfaatkan potensinya dalam inovasi produk masih terbatas. Penelitian ini dilakukan dengan menggunakan pendekatan metode campuran, yang menggabungkan observasi kualitatif, wawancara mendalam dengan produsen makanan lokal, dan survei di antara konsumen untuk menilai preferensi dan potensi pasar. Temuan utama mengungkapkan bahwa meskipun bahan lokal memiliki nilai gizi tinggi dan cita rasa yang khas, bahan tersebut masih kurang dimanfaatkan dalam produk makanan lokal karena keterbatasan pengetahuan dan metode pengolahan. Melalui penelitian ini, prototipe produk makanan dikembangkan menggunakan bahan tradisional seperti talas, singkong, dan pisang, yang diintegrasikan ke dalam resep inovatif yang sesuai untuk konsumen modern. Penelitian ini menyimpulkan bahwa pengembangan produk dari keragaman makanan lokal tidak hanya mendukung pelestarian warisan budaya tetapi juga meningkatkan pertumbuhan ekonomi lokal. Temuan ini penting karena menyoroti jalur berkelanjutan untuk diversifikasi makanan dan mempromosikan sumber daya lokal di pasar makanan yang kompetitif.
