Abstract

Seedless watermelons, both seeds and fruits, possess a significantly higher economic value than their seeded counterparts. Serif Saga Agrihorti, a variety developed by the Tropical Fruit Research Institute, offers several advantages, including a sweet taste, high fruit yield, bright red flesh, and large fruit size. However, it is characterized by a relatively high number of seeds. The development of a new seedless variety from Serif Saga Agrihorti is crucial. Polyploid induction using mutagenic agents like colchicine is an effective method to obtain tetraploid female parents. This study aimed to identify the optimal method and colchicine concentration for inducing polyploidy in watermelons and to produce putative tetraploid plants. Polyploid induction was conducted using two methods: directly applying colchicine solution to plant shoots and soaking seeds in colchicine solution for 24 and 48 hours at concentrations of 0.2% and 0.4%. The observed traits included stem diameter, leaf length and width, stomatal length and width, pollen diameter, pollen viability, male and female flowering periods, harvesting time, fruit weight, fruit diameter, seed count, and seed dimensions (length and width). Data were analyzed using an unpaired t-test using the Statistical Tools for Agricultural Research (STAR) software. The results identified four putative tetraploid genotypes based on morphological observations of pollen diameter, stomatal size, and seed dimensions. In conclusion, seed soaking in colchicine solution effectively induces polyploidy in watermelons compared to shoot application.

Abstract

Kacang koro dari genus Canavalia dapat dimanfaatkan sebagai sumber protein alternatif yang penting untuk ketahanan pangan nasional. Pembudidayaannya dapat diarahkan pada lahan marginal yang ketersediaannya cukup luas di Indonesia. Penelitian ini bertujuan untuk melihat respon pertumbuhan berbagai aksesi kacang koro yang berasal dari tiga spesies berbeda pada dua kondisi lahan yang terpapar salinitas. Penelitian dilaksanakan pada bulan September 2023-Maret 2024 di Pantai Pasir Putih, Bungo Pasang Kota Padang. Sebanyak 5 aksesi Canavalia spp. yaitu 2 aksesi spesies Canavalia gladiata, 2 aksesi spesies C. maritima, dan 1 aksesi spesies C. cathartica ditanam di lahan dengan dua kondisi salinitas yaitu salinitas rendah (1,2 dS/m), dan salinitas sedang (3,8 dS/m). Percobaan didesain dalam Rancangan Acak Kelompok dengan masing-masing dua ulangan sehingga terdapat 20 satuan percobaan. Data dianalisis menggunakan sidik ragam gabungan (combined ANOVA) dan dilanjutkan dengan uji Duncan pada taraf nyata 5%. Analisis korelasi dilakukan untuk melihat hubungan tingkat salinitas dengan variabel pertumbuhan tanaman. Hasil penelitian menunjukkan terjadinya gangguan pertumbuhan kecuali aksesi Cm.Halmahera dan Cm.Bengkulu yang memperlihatkan respons peningkatan pertumbuhan dengan meningkatnya salinitas. Aksesi berinteraksi dengan tingkat salinitas pada pengamatan panjang batang, jumlah cabang dan diameter batang terutama pada umur 24 MST, mengindikasikan periode waktu ini ideal untuk menyeleksi aksesi yang toleran terhadap salinitas.  Korelasi negatif dan kuat antara tingkat salinitas dan pertumbuhan tanaman menunjukkan bahwa peningkatan salinitas menekan pertumbuhan tanaman. Berdasarkan nilai indeks toleransi, maka aksesi Cm. Halmahera dan Cm. Bengkulu dari spesies Canavalia maritima memiliki kemampuan adaptasi yang lebih baik terhadap salinitas dibandingkan aksesi lainnya.

Abstract

The utilization of superior hybrid varieties is pivotal in enhancing national maize productivity. Therefore, the continuous development of cultivars specifically adapted to distinct agroecosystems remains imperative. To that end, this study evaluated six inbred lines and 15 single-cross hybrids derived from a half diallel mating design to assess the combining ability of these inbred lines and examine the agronomic performance and heterotic expression manifested in the resulting hybrids. All genotypes, including the hybrids, inbred parents, and a check variety (P32), were tested using an RCBD with two replications in Nagari Situjuah, West Sumatra, Indonesia. The data were analyzed using F-tests followed by a planned LSD test with SAS software at the 5% significance level. PCA and path analysis were performed using RStudio, while GCA and SCA were analyzed using Diallel-SAS software. Results showed that the UZ 9 line performed the highest GCA for growth, flowering and yield-related traits. Hybrids UZ 3><UZ 9 (H2), P137-1><R2 (H14), and CLYN><R2 (H15) exhibited the best SCA values, coupled with superior agronomic performance, positive and high heterosis, heterobeltiosis, and standard heterosis for yield, achieving up to 11 tons hectare⁻¹, comparable to P32. PCA further supported these findings, which revealed that H2, H14, and H15 were associated with shorter flowering, harvesting periods and higher kernel yield. Path analysis identified kernel weight ear⁻¹ as the most influential variable affecting kernel yield hectare⁻¹. These findings highlight H2, H14, and H15 as promising hybrids with strong potential for further development and evaluation before release as new superior hybrid varieties.

Abstract

The germination process is the key to plant phenology, which significantly influences the success of early plant growth. Some seeds have a dormancy, so the germination process is hampered or does not occur. However, dormancy-breaking treatments in plants have been widely reported, such as breaking the dormancy of sugar palm seeds through physical scarification. This research aims to determine the best scarification position to break the dormancy of sugar palm seeds. This research was carried out at the Seed Technology Laboratory, Faculty of Agriculture, Universitas Andalas from July to October 2023. The design was completely randomized with scarification in two position variations, the operculum (A1) and dorsal (A2) points, repeated thrice. The results showed that the position of seed scarification affected the emergence time of cotyledon petioles and coleoptiles, germination capacity, and seed moisture content. Scarification at the operculum point requires a dormancy break of 16 DAP (Days After Planting) compared to 29 DAP for the dorsal. Seed viability was good in seeds sacrificed at the operculum point, with a germination percentage of 81.94%. Keywords: dorsal, operculum, cotyledon petiole

Abstract

Stunting in children under five remains a significant public health issue in Indonesia, particularly in West Sumatra, where prevalence rates exceed the national average. Addressing this challenge requires improving nutritional intake, focusing on essential micronutrients like zinc (Zn) and iron (Fe). Biofortification is a promising agricultural strategy to enhance the nutritional quality of staple crops such as rice. This study aims to explore and evaluate the Zn and Fe content of local rice genotypes from West Sumatra, which hold potential for biofortification programs.Twenty-eight rice genotypes, including 27 local genotypes and one control (Inpari Nutri Zinc), were analyzed for Zn and Fe content. The results showed that the control variety, Inpari Nutri Zinc, exhibited the highest Zn (31.30 ppm) and Fe (19.85 ppm) content. Among the local genotypes, Puluik Mutia (Zn: 28.40 ppm, Fe: 18.30 ppm), Kuning Aro (Zn: 27.60 ppm, Fe: 18.20 ppm), and Rampai Kuning (Zn: 26.20 ppm, Fe: 18.05 ppm) displayed the highest Zn levels, while Manggung (Fe: 18.85 ppm) had the highest Fe content. These findings highlight the significant variability in micronutrient content among local genotypes, emphasizing their potential as germplasm for biofortification breeding programs.This research represents the first systematic exploration of Zn and Fe levels in local rice genotypes from West Sumatra. The novelty lies in identifying high-Zn and Fe genotypes, particularly those with firm texture preferences, which could support biofortification efforts and provide a sustainable solution to combat stunting. Future research should focus on environmental interactions and agronomic practices to further optimize the micronutrient content in local rice varieties

Abstract

Varietas semangka hibrida memiliki produktivitas dan keseragaman yang tinggi sehingga diminati oleh konsumen. Penelitian ini bertujuan untuk mengevaluasi beberapa hibrida hasil persilangan antara galur inbrida dengan varietas Serif Saga Agrihorti (SSA) sebagai tetua jantan. Percobaan menggunakan rancangan acak kelompok (RAK) dengan tiga ulangan, melibatkan 12 hibrida hasil topcross dan Serif Saga Agrihorti (SSA) sebagai satu varietas pembanding. Semua genotipe ditanam di lapangan dengan mengikuti praktik agronomi semangka yang standar. Karakteristik yang diamati meliputi waktu berbunga jantan dan betina, umur panen, serta diameter dan bobot buah, ketebalan kulit buah, tingkat kemanisan, dan jumlah biji fertil dan biji steril. Data dianalisis menggunakan ANOVA dilanjutkan dengan uji BNT (Beda Nyata Terkecil). Variabilitas genotipik dan fenotipik, heritabilitas dan koefisien korelasi genotipik dan fenotipik  karakter, diestimasi berdasarkan partisi nilai ragam dari ANOVA. Hasil penelitian menunjukkan variabilitas genetik yang luas pada karakter umur berbunga jantan dan betina, serta bobot buah. Nilai duga heritabilitas yang tinggi diperoleh pada karakter umur berbunga jantan dan betina, bobot buah, diameter buah dan jumlah biji fertil. Empat genotipe hibrida yaitu G1, G6, G8, dan G10, menunjukkan bobot buah dan tingkat kemanisan yang lebih tinggi dibandingkan varietas SSA. Berdasarkan heritabilitas yang tinggi pada karakter bobot buah, maka keempat hibrida ini berpotensi untuk dikembangkan menjadi varietas semangka hibrida baru atau dimanfaatkan sebagai populasi dasar untuk perakitan varietas bersari bebas.

Abstract

Persimmon, kesemek, buah kaki atau manggih hutan dalam bahasa minang adalah berbagai sebutan untuk buah yang dihasilkan oleh tanaman pohon Diospyros kaki Thunb. Buah kesemek mengandung berbagai nutrisi penting, anti toksik dan bahkan anti kanker. Kesemek merupakan tanaman sub tropika sehingga di Indonesia kesemek hanya beradaptasi pada ketinggian ± 1400 mdpl, seperti Alahan Panjang. Petani biasanya menggunakan anakan untuk perbanyakan, namun akibatnya tanaman membutuhkan waktu yang lama untuk berbuah, lebih dari 8 tahun. Kegiatan ini bertujuan untuk mentransfer teknologi sambung pucuk menggunakan anakan (root-sucker) sebagai batang bawah (root-stock) sebagai upaya untuk mendapatkan perbanyakan kesemek secara cepat dan tanaman cepat berbuah. Mitra kegiatan ini adalah kelompok tani Harapan Baru yang berada di Batu Bagiriek Alahan Panjang Kabupaten Solok, Sumatera Barat dari bulan Oktober hingga Desember 2016. Metode kegiatan meliputi penyuluhan, demonstrasi dan pelatihan grafting. Hasil kegiatan adalah petani meningkat pengetahuannya tentang manfaat buah kesemek, teknik budidaya dan pasca panen serta mampu melakukan grafting atau penyambungan pada kesemek menggunakan root-sucker (anakan) sebagai batang bawah. Berdasarkan hasil uji statistika menggunakan analisis Likert, kegiatan pengabdian masyarakat yang dilakukan memiliki nilai indeks 92, menunjukkan bahwa kegiatan yang dilakukan bermanfaat atau berhasil mentransfer pengetahuan dan juga keterampilan kepada petani.

Abstract

Sweet corn is a high-value commodity whose productivity can be improved through hybrid variety development. The development of superior hybrids depends on establishing inbred lines with superior agronomic performance and broad phenotypic variability as the basis for parental selection. This study aimed to evaluate agronomic traits and phenotypic variability, analyze correlations among traits, perform principal component analysis (PCA), and apply the Multi-Trait Genotype–Ideotype Distance Index (MGIDI) for multi-trait selection in S4 sweet corn inbred lines. The experiment was conducted at the Experimental Farm of Universitas Andalas from January to April 2025. An Augmented II design consisting of two blocks was used with 36 S4 inbred lines, comprising 33 test lines and 3 check lines. Results revealed wide phenotypic variability for most agronomic traits, except ear diameter and total soluble solids. Yield exhibited positive correlations with plant height, ear length, and ear diameter, but negative correlations with flowering and harvest traits. In contrast, total soluble solids were not significantly correlated with the other agronomic traits. Principal component analysis (PCA) showed that most agronomic traits contributed to the variation among inbred lines, whereas total soluble solids had a relatively small contribution. Based on multi-trait selection using MGIDI, seven inbred lines, i.e. CD3, MM1, AG2, PN1, CD2, IN2, and SL1, were identified as the closest to the ideotype. These lines have the potential to be prioritized as parental lines and should be further evaluated in the S5 generation and subjected to combining-ability evaluations in hybrid sweet corn breeding.
