Abstract

Soybeans(Glycine max (L.) Merill) is an important food crop that served as an alternative source of protein in Indonesia, due to its very high grain protein content ranging from 40% to 50%. This research is intended to determine genotypic variance components, and heritability of important characters in a soybean population at two planting space. The field experiment was conducted using a randomized block design with 3 replications. Six varieties including Argomulyo, Anjasmoro, Kaba, Burangrang, Gema, Grobogan and three line including KM1, KM-12 and KM25 were grown with two spacing plants, ie, 40cm x 20 cm and 40cm x 15 cm in a plot measuring 3 m in lenght and 2 m in wide. Characters Observed were plant height, flowering date, harvesting date, seed number per plant, grain weight per plant, 100-grain weight, and grain yield  m-2. Generally,the result indicate that all characters vary greatly among genotypes but not significantly different between planting space. Specificaly, genotypes showed high variability in flowering date, harvesting date, grain yield m-2  and 100-grain weight, but not for other traits. The value of genotypic varian components was different from 0 only for flowering date, harvesting date, grain yield m-2 and 100-grain weight. Heritability estimated were diffrent from 0 for flowering date, harvesting date, grain yield m-2 and 100-grain weight, but not for other characters. Keywords : soybean, variability, varians component , heritability

Abstract

Kecipir (Psophocarpus tetragonolobus (L.) DC) dijuluki sebagai kedelai daerah tropis dengan potensi kandungan gizi tinggi. Kurangnya informasi mengenai komponen keragaman dan heritabilitas dalam pemuliaan kecipir menjadi salah satu penyebab belum berkembangnya program pemuliaan kecipir di Indonesia. Penelitian ini bertujuan untuk memperoleh informasi ragam, heritabilitas dan hubungan antar karakter kecipir. Penelitian dilakukan di tiga lingkungan yaitu dua lingkungan di Bogor, dan satu lingkungan di Palembang, pada bulan Januari 2019 sampai dengan Juni 2020. Pengujian dilakukan terhadap 11 genotipe kecipir dan 11 karakter pengamatan. Hasil menunjukkan karakter umur berbunga dan jumlah biji per polong memiliki keragaman genetik yang luas. Nilai heritabilitas tinggi ditunjukkan oleh karakter jumlah biji per polong (89.48%), umur berbunga (83.32%), panjang polong muda (70.97%) dan bobot 100 biji (68.63%). Hasil analisis lintas menunjukkan karakter produktivitas polong muda (1.07), bobot biji per plot (0.81), umur berbunga (0.29), panjang polong muda (0.17), lebar polong muda (0.12), bobot biji per tanaman (0.09), dan bobot 100 biji (0.01) memiliki pengaruh langsung positif terhadap produktivitas biji kecipir. Umur berbunga, jumlah biji per polong dan bobot biji per tanaman merupakan karakter yang tepat menjadi kriteria seleksi dalam merakit kecipir berproduksi tinggi. Kata kunci: analisis lintas, keragaman genetik, korelasi

Cabai rawit (Capsicum annuum L.) merupakan komoditas hortikultura penting dengan nilai ekonomi tinggi di Indonesia. Produktivitas cabai rawit nasional tahun 2023 mencapai 7,05 t/ha, meningkat 4% dari tahun sebelumnya, namun masih perlu ditingkatkan untuk memenuhi kebutuhan konsumsi masyarakat. Penelitian ini bertujuan untuk mengetahui pewarisan karakter dan kemajuan genetik harapan hasil persilangan cabai rawit UNRI C18 dan UNRI C11 pada populasi F2. Penelitian dilaksanakan di kebun percobaan dan Laboratorium Pemuliaan Tanaman Fakultas Pertanian Universitas Riau dari Januari hingga Agustus 2025, menggunakan rancangan persilangan biparental dengan materi genetik yang terdiri dari tetua 1 (P1) UNRI C18, tetua 2 (P2) UNRI C11, populasi F1, dan populasi F2. Pengamatan dilakukan pada sembilan karakter kuantitatif meliputi umur berbunga, umur panen, bobot buah per tanaman, jumlah buah per tanaman, bobot per buah, panjang buah, panjang tangkai buah, diameter buah, dan tebal daging buah. Data dianalisis menggunakan metode pendugaan heritabilitas Mahmud-Kramer untuk menghitung heritabilitas arti luas serta kemajuan genetik harapan dengan intensitas seleksi 10%. Hasil penelitian menunjukkan populasi F2 memiliki keragaman dan segregasi lebih tinggi dibandingkan dengan F1. Nilai heritabilitas arti luas berkisar 0,07 – 0,76. Karakter produktivitas menunjukkan heritabilitas tinggi, yaitu bobot buah per tanaman (0,56) dan jumlah buah per tanaman (0,51). Kemajuan genetik harapan tertinggi ditemukan pada bobot buah per tanaman (117,35 g) dan jumlah buah per tanaman (99,27 buah), menunjukkan potensi seleksi sangat baik untuk meningkatkan produktivitas.

Abstract

Winged bean is a plant with a high seed protein content equivalent to soybeans. Indonesia is one of the central origins in southern Asia. However, there are still only a few superior varieties that can be widely cultivated. One effort to increase productivity is by growing improved varieties. This study aimed to identify promising winged bean lines with high and stable yield potential. The experiment was conducted in three environments, i.e., two planting seasons in Bogor and one in Palembang from January 2019 to June 2020. A total of 11 winged bean genotypes were tested and observed for grain yield characters. Parametric analysis methods were used to obtain information on the stability of 11 winged bean genotypes across the three environments. Grain yield was significantly affected by G x E interaction and, therefore, was subjected to stability analyses. Genotypes H1(P), L2, and H4(P) were classified as stable. This genotype had similar characteristics with stable grain yield in three test environments. Keywords: G x E interaction; seed yield; parametric stability, underutilized legume

Abstract

Soursop (Annona muricata L.) is a tropical fruit plant with high economic value; however, its cultivation is limited by seed dormancy, which delays germination. This study aimed to determine the most effective sulfuric acid (H₂SO₄) concentration for breaking seed dormancy and improving seed viability of soursop. The experiment was conducted at the Greenhouse and Plant Breeding Laboratory, Faculty of Agriculture, Universitas Riau, and implemented using a completely randomized design with four treatments: 0% (control), 70%, 75%, and 80% H2SO4 concentration. Each treatment was repeated five times. A total of 20 experimental units were obtained, each consisting of 25 seeds, for a total of 500 seeds used in the experiment. The results indicated that sulfuric acid treatment significantly affected most germination parameters. Seeds soaked in a 75% sulfuric acid solution exhibited the fastest germination time (28.40 Day After Planting), the highest germination percentage (88.80 %), and the strongest seed vigor (5.55%). These findings suggest that chemical scarification with 75% H₂SO₄ for 30 minutes can serve as a practical and efficient pre-sowing treatment to improve seedling establishment in soursop propagation.

Abstract

National chili demand continues to increase, but productivity at the farmer level remains low due to attacks by the whitefly (Bemisia tabaci Genn.) virus. Benai Kecil Village, Benai District, Kuantan Singingi Regency, Riau, is a horticultural center with low chili productivity (4–5 tons/ha), far below the potential of commonly used superior varieties. This community service activity aims to improve farmers' knowledge and skills in chili cultivation by initiating the use of the superior virus-resistant Neno variety. The program was implemented for five months with stages of socialization, field practice, mentoring, monitoring, evaluation, and follow-up. The results of the activity indicated that farmers improved their understanding and skills in chili cultivation techniques, including seeding, soil cultivation, maintenance, and pest and disease control. The evaluation showed that the Neno chili variety has the potential to be developed because it is adaptive to dynamic climate change and effectively reduces the risk of curly virus attacks. In addition, the use of virus-resistant varieties can also support environmentally friendly pest and disease control. This program demonstrates that the development of the superior Neno variety has the potential to be a sustainable strategy for increasing chili production while simultaneously strengthening food security and farmer welfare.

Abstract

This community service program aims to improve farmers' knowledge and skills in cultivating chili plants and preventing geminivirus infection, a major constraint in production. The activity was carried out through outreach activities covering the stages of land cultivation, virus infection prevention techniques, whitefly population control as a vector, land clearing of weeds that are hosts of geminivirus, sanitation of infected plants, and proper pesticide use. In addition, participants were also introduced to the use of chili varieties resistant to the yellow geminivirus as an alternative sustainable solution. The results of the activity showed an increase in farmers' understanding of healthy cultivation strategies and integrated pest control, with an average score increasing from 45% to 85%, with the vector control aspect increasing from 30% to 90%. This outreach is expected to reduce the level of virus infection and increase chili productivity.
