Abstract. Fadli M, Farid M, Yassi A, Nasaruddin, Anshori MF, Nur A, Suratman. 2021. Evaluation of the advanced yield trial on tropical wheat (Triticum aestivum) mutant lines using selection index and multivariate analysis. Biodiversitas 23: 540-547. The development of adaptive wheat (Triticum aestivum L.) mutant lines in tropical climate is a long-term solution. The advanced yield trial is an important stage in this development, which is carried out using a selection index and multivariate analysis. This study aims to determine the selection effectiveness of tropical wheat mutant lines by using a selection index and multivariate analysis. the study was conducted in three locations, which included two locations for the follow-up yield test in Kelara Village and Ujung Bulu Village (South Sulawesi, Indonesia), and the third location for the selection validation in Padang Magek Village (West Sumatra, Indonesia). This study was designed by a nested Randomized Complete Block Design (RCBD), with replications nested in locations. The samples included 16 wheat genotypes (13 mutant lines and three comparison varieties) that were replicated three times. The result showed that the selection of tropical wheat mutant lines using selection index and multivariate analysis were considered effectively with high determination value of 0.57 (57%). The results of the selection index show that seven lines were recommended for multi-location trials since they had a better selection index potential than Dewata variety.

Abstract. Nasaruddin, Farid M, Anshori MF, Nur A, Iriany N, Fadhilah AN. 2025. Morphophysiological evaluation of hybrid maize lines from peak and test crosses for high-yield development. Biodiversitas 26: 5204-5210. The increasing demand for maize in Indonesia amid stagnant productivity underscores the need for innovative breeding approaches to enhance yield potential and resilience. This study integrates morphophysiological trait analysis with hybrid maize lines derived from transgressive segregants and elite line, aiming to identify promising genotypes and key traits associated with high productivity under tropical conditions. A total of 96 genotypes, consisting of 60 hybrids, 20 parental lines and 4 commercial controls, were evaluated using an augmented design. Observations were made on agronomic and physiological traits. This is the first report combining peak and test cross schemes with morphophysiological evaluation in tropical maize, which broadens the genetic base and addresses the limitation of narrow parental pools. Several hybrid maize lines, particularly G29 (8.7 t.ha-1), G28, and G39, outperformed their parents in yield performance. Traits such as cob weight, number of seeds per row, and plant height exhibited high heritability and strong direct effects on yield, highlighting their suitability as selection criteria in breeding programs. Overall, integrating source traits (e.g., plant height, chlorophyll index) and sink traits (e.g., cob characteristics) provides an effective strategy for developing high-yielding and resilient maize hybrids suitable for smallholder-based production systems in tropical environments.

Abstract. Sofyan, Rosmana A, Nasaruddin, Bahrun H, Kurniawan, Syakur A, Risal D. 2025. Diversity and biofertilizer potential of root endophytic fungi in Arabica coffee. Biodiversitas 26: 5977-5988. Sustainable Arabica coffee cultivation requires eco-friendly biological inputs to improve plant growth and soil quality. This study explored the diversity and physiological potential of root endophytic fungi isolated from Arabica coffee plants at two age-structured plots within one village in Maros, South Sulawesi, Indonesia, and evaluated their capacity to quantify phytohormone-related signals and assess compost enrichment. Endophytic fungi were isolated from coffee roots and characterized morphologically to the putative genus level, while biochemical assays estimated IAA-equivalents and GA-like (GA3) compounds. A randomized block design was used to assess compost decomposition and biofertilizer responses of Arabica seedlings in non-sterile soil. Results showed that a total of fourteen isolates were obtained, with Trichoderma spp. dominating young roots (<3 years) and Aspergillus, Penicillium, and Paecilomyces more common in older roots (>10 years). Isolate 5C10BM produced the highest IAA-equivalent signal (3.02 ppm), while P11 yielded the highest GA-like signal (8.14 ppm) and showed a trend toward higher compost nitrogen content relative to the uninoculated control. Compost analysis showed that isolate 6C10BM increased C-organic (20.07%), isolate 11C3BM showed nitrogen levels of 1.19% and isolate 14C3BM elevated phosphorus (0.63%) and potassium (0.42%). Plant assays revealed that isolate 2C10BM increased seedling height (45.4 cm), whereas 9C10BM enhanced leaf number and area. The study demonstrates functional diversity among endophytic fungi, with strain-specific capabilities, particularly in isolates 5C10BM, 11C3BM, and 14C3BM, which exhibited indicative traits relevant to biofertilizer and compost-activating potential. These findings provide insights into endophyte-associated functional traits; future work will include molecular identification and verification of root colonization.
