Abstract

Cayenne peppers (Capsicum annuum L.) are horticultural commodities with high economic value and increasing market demand, both for household consumption and large-scale processing industries. However, cayenne pepper productivity in Indonesia remains relatively low, partly due to the limited availability of fertile land. One potential solution to this problem is the utilization of marginal lands, including ultisols. Ultisols possess chemical characteristics that are less favorable for optimal plant growth, such as low pH, poor nutrient content, and high aluminum saturation. There fore, this study aimed to obtain information on cayenne pepper genotypes that can adapt well and produce optimally on ultisols. The research was conducted at the Experimental Garden of the Faculty of Agriculture, University of Bengkulu, from May to October 2023, using a Randomized Complete Block Design (RCBD) with three replications. Observed parameters included plant height, first dichotomous height, stem diameter, number of dichotomous points, total leaf area, shoot dry weight, stomatal density, days to first harvest, number of fruits per plant, fruit length and diameter, fruit weight per plant, and percentage of marketable fruits. Data were analyzed using ANOVA at a 5% significance level and followed by Duncan’s Multiple Range Test (DMRT) at the same level. The results indicated significant differences among genotypes in most growth and yield parameters. The genotypes ‘Iggo’ and ‘Lajang’ exhibited superior performance, with the highest dry biomass weight and the highest fruit weight per plant. These findings suggest that the ‘Iggo’ and ‘Lajang’ genotypes hold strong potential for cultivation on Ultisol soils to support sustainable national cayenne peppers production improvement.

Abstract

This study aimed to estimate genetic and phenotypic variability, as well as heritability values, in 41 Cayenne pepper cultivars based on vegetative traits.  The research was conducted from May to October 2024 at the Experimental Farm of the Faculty of Agriculture, University of Bengkulu, situated in Beringin Raya village, Bengkulu City, at an elevation of 10 m above sea level.  A Randomised Complete Block Design (RCBD) was employed with a single factor consisting of 41 cultivars with three replications, each comprising 20 plants per replication.  The results revealed a wide range of genetic variability for traits such as plant height, first dichotomous height, number of leaves, leaf area, leaf greenness, number of dichotomous points, canopy area, stem diameter, shoot fresh weight, and shoot dry weight.  High phenotypic variability was observed across all evaluated traits.  High heritability was found in the trait of first dichotomous height.  Moderate heritability was observed for plant height, number of leaves, leaf greenness, number of dichotomous points, canopy area, shoot fresh weight, and shoot dry weight. Low heritability was detected in leaf area, stomatal density, and stem diameter.

Abstract

Persilangan tomat buah besar dengan buah kecil akan menghasilkan keragaman yang tinggi pada populasi F2. Penentuan karakter seleksi dan seleksi individu pada populasi F2 sangat dibutuhkan untuk mendapatkan genotipe terbaik. Penelitian bertujuan untuk menentukan karakter-karakter yang memberikan kontribusi langsung dan tidak langsung terhadap hasil dan memperoleh individu F₂ unggul yang berpotensi sebagai galur terbaik. Penelitian dilaksanakan di Kelurahan Kandang Limun, Kota Bengkulu dengan ketinggian 10 m dpl (dataran rendah). Populasi yang digunakan adalah F2 hasil persilangan tomat buah besar dengan buah kecil sebanyak 200 tanaman. Hasil penelitian menunjukkan bahwa karakter jumlah buah per tanaman merupakan karakter seleksi utama. Karakter tinggi tanaman, umur berbunga, panjang buah, diameter buah, dan tebal daging buah juga berperan penting sebagai pendukung peningkatan hasil. Dua puluh genotipe F₂ terbaik yang terseleksi adalah TMU-9, TMU-184, TMU-215, TMU-198, TMU-164, TMU-191, TMU-214, TMU-204, TMU-10, TMU-163, TMU-193, TMU-194, TMU-44, TMU-207, TMU-213, TMU-195, TMU-61, TMU-220, TMU-166, dan TMU-201.  Kata kunci: analisis lintas, genotipe, kemajuan genetik, indeks seleksi
