Abstract. Makmur, Farid M, Ala A, Mandja K, Anshori MF, Fadhilah AN. 2024. The selection index of S3 corn convergent breeding population based on multivariate analysis. Biodiversitas 25: 1097-1103. Corn is one of the most important and strategic food crops in the world, including Indonesia. Increasing corn production through a plant breeding program by assembling hybrid varieties begins with developing a convergent breeding population and index selection. The research aims to identify genetic variance and the effectiveness of selection indices in selecting high-yield S3 cross populations. The research was carried out in Rea Village, Binuang Sub-District, Polewali Mandar District, West Sulawesi from July to November 2022. The research used an augmented design with four blocks. Sixty-six lines were derived from 4 double cross populations and 8 populations of the S3 generation multiple-cross population, as well as 9 check varieties (NK7328, Pioneer 36, Bisi 18, Bisi 2, NK99, Nasa 29, JH45, Bisi 9, and NK212) were used in this study. The results indicate that the length of cobs (5.98;73.59%), length of seed cobs (7.06; 79.46%), weight of 100 seeds (7.75; 89.30%), and weight of seeds per cob (7.84; 65.59%) have moderate genetic variance and high heritability. The characteristics of stem diameter, yield percentage, and weight of seed per cob were effectively used in the selection index formulation. Based on the index selection, there were 14 potential corn lines with a good performance, recommended for the next hybridization stage.

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.
