Abstract

Shallot anthracnose, caused by Colletotrichum gloeosporioides, is a devastating disease in a tropical country with high humidity and rainfall. Chemical control of anthracnose is neither economical nor eco-friendly, and genetic resistance is considered an efficient management method. This study aimed to determine the resistance groups of several shallot varieties and predict resistance heritability characteristics. In this study, a total of 13 Indonesian shallot varieties were evaluated for anthracnose resistance and separated into two groups, resistance and susceptible, based on K-means clustering developed by using disease resistance/susceptibility characteristics such as incubation period, disease incidence, disease severity, and spot diameter. The results indicate that the Agrihorti, Maja Cipanas, Batu Ijo, and Rubaru varieties were identified as resistant groups based on lower disease severity and incidence, smaller spot diameter, and longer incubation period. Maja Cipanas and Rubaru were more consistent in all variables, which is recommended as a source of genetic resistance genotypes. On the other hand, the Biru Lancor, Bima Brebes, Srikayang, Violetta, Slupu Merah, Pancasona, Sakato, Katumi, and Kuning varieties were identified as susceptible groups based on high disease severity and incidence, large spot diameter, and short incubation period. Keywords: susceptibility characteristics, genetic resistance, k-means clustering, disease severity

Abstract

Callus induction is an important step in indirect somatic embryogenesis. The aim of this study was to obtain an optimal medium for the callus formation of plantain bananas (cv. Kepok). The research was conducted from May to August 2022 at the Tissue Culture Laboratory of PT. ITCI Kartika Utama, Penajam Paser Utara District, East Kalimantan. The explant used an immature male flower of plantain banana (cv. Kepok). The experiment used a completely randomized design with two factors concentration of 2,4-D (1,2 and 4 ppm) and BAP (5, 10, and 15 ppm). The appearance of callus was monitored daily until it developed explants. On the final observation day, the percentage of explants with callus, as well as the color and texture of the callus, were assessed. The research findings suggest that the optimal medium for inducing callus in male banana flower explants was MS medium supplemented with 2 ppm 2,4-D and 5 ppm BAP. This medium resulted in calluses that exhibited a yellowish-white color and a compact texture. Keywords: callus morphology; genetic improvement; plant growth regulator; tissue culture; triploid banana

Abstract

Upland Soil Test Kit (PUTK) is a rapid soil analysis kit that estimates the nutrient availability in soil. From previous studies, tomato plant production showed a good correlation with available phosphorus (P) and potassium (K) analysis using the PUTK. This study aimed to find the optimal P fertilizer rate based on PUTK analysis for tomato fertigation. This experiment was carried out using a randomized complete block design, four replications with a single factor, namely P fertilizer rate comprising 0% X, 50% X, 100% X, 150% X, and 200% X, with X the recommended P fertilizer of PUTK on moderate P availability (175 kg ha­1). The ANOVA showed that P fertilizer did not significantly affect the vegetative growth, production, and fruit quality of tomatoes. It means that PUTK analysis had low accuracy as a basis for determining the optimum P fertilizer rate for tomato fertigation. The low accuracy could be due to PUTK underestimating the status of soil P availability. Mechlich-1 analysis showed that the experimental field had high P availability (44.6 ppm), while PUTK analysis still indicates moderate P availability. This shows that PUTK needs to be developed further, especially quantifying the result to help make informed and accurate decisions.

Abstract

Rapid multiplication of potato seed using cuttings is a pivotal strategy for ensuring seed availability. This study aimed to elucidate the interactive effects of node number, paclobutrazol concentration, and planting density on seed potato and cutting productions. The study consisted of two experiments. The first experiment evaluated two genotypes (Granola and PKHT-6) with one or two nodes per cutting. The second experiment investigated planting density (one, three, or five plants per polybag) and paclobutrazol concentration (0, 15, 30, and 45 mg L-1). Notably, node number did not significantly influence cutting success, despite genotype-specific and interactive effects on vegetative parameters like plant height, stem diameter, leaf number, and root length. Planting density had no statistically significant impact on all vegetative parameters but demonstrably affected all production parameters. Conversely, paclobutrazol concentration significantly affected all vegetative parameters and influenced all production parameters except tuber weight per plant. From the results of this research, the use of single cutting is more recommended because it will obtain more plant material compared to two-node cuttings. Thus, in a more global context of potato development, this has the potential to increase the production of potato seeds from cuttings twice as much as the current seed production. The use of three plants/polybags is more recommended since it will produce more tuber but not different with five plants, and the use of paclobutrazol 15 mg L-1 is also recommended to increase the number of tubers. In this way, the production costs of G0 potato seeds can be reduced so that the availability of G0 potato seeds will be more guaranteed and affordable. Keywords: Granola; PKHT-6; rapid multiplication; tuber production

Abstract

Informasi tentang karakter seleksi dan pewarisan sifatnya sangat penting bagi program pemuliaan tanaman. Penelitian ini bertujuan untuk memperoleh karakter seleksi dan informasi pewarisan sifatnya terhadap cekaman naungan pada tanaman tomat. Populasi persilangan Biparental SSH3 x 4979 (tetua, F1, backcross dan F2) ditanam pada kondisi tanpa naungan (N0) dan kondisi cekaman naungan paranet 50% (N50) di Kebun Percobaan Pusat Kajian Hortikultura Tropika – Institut Pertanian Bogor, Pasir Kuda, Bogor, Jawa Barat, Indonesia. Hasil penelitian memperlihatkan bahwa karakter kehijauan daun, fruit set, jumlah buah dan bobot buah per tanaman merupakan karakter seleksi toleran naungan pada tanaman tomat. Terdapat aksi gen dominan dan epistasis duplikat pada karakter-karakter tersebut baik pada kondisi normal maupun kondisi cekaman naungan kecuali karakter fruit set pada kondisi tanpa naungan. Dominansi pada karakter-karakter tersebut bersifat over dominan pada kondisi tanpa naungan, namun dominan parsial pada kondisi cekaman naungan. Ragam aditif lebih berperan dibandingkan ragam non aditif pada karakter kehijauan daun, fruit set, jumlah dan bobot buah per tanaman pada kondisi normal namun sebaliknya dimana ragam non aditif lebih berperan dibandingkan ragam aditif pada karakter-karakter tersebut saat kondisi cekaman naungan. Seleksi pada generasi awal seperti generasi F2 dapat efektif dilakukan pada karakter-karakter tersebut pada kondisi tanpa naungan, namun seleksi pada kondisi cekaman naungan terhadap karakter-karakter tersebut lebih baik dilakukan pada generasi lanjut.

Abstract

Beras berwarna, khususnya beras hitam, merupakan jenis beras fungsional yang kaya akan antosianin dan memiliki nilai gizi tinggi. Seiring meningkatnya kesadaran masyarakat terhadap pola hidup sehat, permintaan terhadap beras hitam pun meningkat. Namun, Indonesia saat ini baru memiliki satu varietas unggul padi hitam, yaitu Jeliteng, sehingga diperlukan alternatif varietas baru yang memiliki mutu fisik dan kimia gabah serta beras yang baik. Salah satu sumber potensial adalah galur-galur dihaploid hasil persilangan melalui kultur antera, tetapi informasi mengenai mutu fisik dan kimia gabah serta berasnya masih terbatas, padahal data tersebut penting untuk mendukung seleksi calon varietas unggul yang adaptif dan disukai konsumen. Penelitian ini bertujuan untuk mengevaluasi mutu fisik dan kimia gabah serta beras dari galur-galur dihaploid padi hitam hasil kultur antera. Materi genetik terdiri atas 14 galur dihaploid dan dua varietas pembanding, yaitu Jeliteng (beras hitam) dan Aek Sibundong (beras merah). Pengujian meliputi karakter fisik (rendemen beras kepala, rendemen beras pecah kulit, panjang dan bentuk beras, persentase butir kapur, dan warna aleuron), kimia (kadar amilosa dan suhu gelatinisasi), serta uji organoleptik nasi (tekstur, rasa, aroma, dan penampilan). Hasil penelitian menunjukkan bahwa enam galur (DK-2, DK-8, DK-9, DK-11, DK-12, dan DK-14) memiliki kadar amilosa lebih rendah dan rendemen beras lebih baik dibanding Jeliteng. Dua galur, DK-6 dan DK-7, menghasilkan nasi lebih pulen dengan kadar amilosa 18,41% dan 19,11%, serta rendemen beras pecah kulit masing-masing sebesar 68% dan 66%. Temuan ini menunjukkan potensi beberapa galur dihaploid sebagai calon varietas unggul padi hitam yang adaptif dan disukai konsumen.

Abstract

The improvement of eggplant yield through breeding is crucial. Doubled haploid technology has accelerated the development of varieties. This study utilized doubled haploid anther culture-derived lines (confirmed through flow cytometry and morphology) developed from embryos from a previous study to evaluate the morpho-agronomic performance and yield of doubled haploid eggplant lines. The experiment used a randomized complete block design (RCBD), three replications, and one factor, namely genotype (35 doubled haploid lines, three F1 varieties). Observation was made on plant height, dichotomous height, stem diameter, days to flowering and harvesting, fruit length, fruit diameter, weight per fruit, number of fruits, and fruit yield per plant. The data were analyzed using ANOVA, t-Dunnett, Tukey-Kramer at a 5% level, Pearson correlation coefficient, and selection index. The results showed significant variability in the population of doubled haploid lines. Fruit yield was positively correlated with plant height, dichotomous height, stem diameter, days to flowering, fruit length, and weight per fruit, but negatively correlated with the number of fruits per plant. These variables can be used as selection criteria because of their high heritability and genotypic coefficients of variation. The selection index revealed that the high-yielding doubled haploid lines with desirable morpho-agronomic traits were RS-P2, RS-P6, RS-P9, RS-P14, RS-P18, RS-H19, RS-H20, RS-H23, RS-H27, RS-H3, RS-M31, RS-M32, RS-M33, RS-M34, and RS-M37. The selected lines with high yield and good quality fruit, similar to the commercial hybrid parent, were Hitavi’s derived lines. All selected lines serve as the genetic basis for production improvements and long-term breeding programs for sustainable and productive eggplants that benefit farmers.
