Aplikasi paclobutrazol pada tanaman padi untuk mengurangi tinggi batang merupakan strategi adaptasi terhadap perubahan iklim yakni agar tanaman lebih tahan rebah. Namun demikian, pengaruh aplikasi paclobutrazol terhadap kualitas beras masih jarang diteliti. Penelitian bertujuan untuk mengkaji kualitas mutu beras dari empat varietas tanaman padi yang diberi perlakuan paclobutrazol. Penelitian dilaksanakan pada bulan Februari-Juli 2021 di Kebun Percobaan Sawah Baru IPB, Bogor. Empat varietas yakni IPB 3S, Inpari 42, Hipa 18, dan Tarabas diperlakukan dengan paclobutrazol (K1 = 0 ppm, K2= 150 ppm, K3 = 300 ppm, K4 = 450 ppm, K5 = 600 ppm), yang diaplikasikan melalui daun saat tanaman bunting sebelum malai muncul. Hasil penelitian menunjukkan bahwa perlakukan paclobutrazol memengaruhi mutu beras khususnya persentase beras pecah kulit, beras giling dan beras kepala, bentuk beras, serta kandungan amilosa. Varietas padi memberikan respon berbeda terhadap perlakuan paclobutrazol. Konsentrasi 150 ppm mulai memengaruhi mutu beras yakni meningkatkan beras pecah kulit pada semua varietas, beras giling pada IPB 3S dan Inpari 42, dan beras kepala serta kandungan amilosa pada IPB 3S dan Hipa 18; tetapi menurunkan beras kepala pada varietas Tarabas dan kandungan amilosa pada Inpari 42. Perlu penelitian lebih lanjut residu paclobutrazol pada beras untuk memastikan keamanan pangan. Kata kunci: beras giling, beras kepala, cuaca ekstrim, perubahan iklim, varietas padi

Benih padi yang baru dipanen umumnya tidak berkecambah walaupun dikecambahkan pada kondisi optimum yang disebut after-ripening, dan secara alamiah akan hilang setelah waktu tertentu. Penelitian ini bertujuan melakukan karakterisasi agro-morfologi dan menetapkan periode after-ripening benih 5 lanras potensial di Timor-Leste. Penelitian dilaksanakan pada bulan April 2018-November 2019. Penanaman dan pengamatan karakter agro-morfologi 5 lanras potensial Timor-Leste, yaitu Hare R-oitu, Fos Mean, Hare Belit, Hare Nona Portu, dan Ale Mamea Ula Lesa, dilaksanakan di Desa Caibada Distrik Baucau, Timor-Leste. Pengamatan periode after ripening dan mutu benih ke lima lanras tersebut dilaksanakan di Laboratorium Pengujian dan Penyimpanan Benih, Departemen Agronomi dan Hortikultura, IPB University, dan dirancang dalam rancangan acak lengkap (RAL) dua faktor dengan empat ulangan. Faktor pertama adalah 5 lanras tersebut di atas dan faktor kedua adalah periode simpan yang terdiri atas 2, 3, 4, 5, 6, 7, dan 8 minggu setelah panen (MSP). Hasil penelitian menunjukkan bahwa 5 lanras potensial di Tinmor-Leste mempunyai keragaan tanaman yang pendek (76.3-105.50 cm), tergolong berumur sedang (129-141 HSS), dan jumlah anakan produktif tinggi (17.5-53.50 anakan), kecuali Ale Mamea Ula Lesa. Lima lanras tersebut mempunyai potensi produktivitas yang tinggi berkisar 8.1-9.8 ton ha-1. Periode after-ripening lanras Hare Belit dan Hare Nona Portu berakhir pada 2 MSP, Hare R-oitu pada 6 MSP, sedangkan Ale Mamea Ula Lesa dan Fos Mean pada 8 MSP. Semakin lama benih disimpan rasio kandungan ABA/GA3 semakin menurun dari 0.53-1.22 ppm pada 2 MSP menjadi 0.45-0.93 ppm pada 4 MSP. Lanras Hare Belit dan Hare Nona Portu merupakan lanras yang potensial dikembangkan menjadi varietas nasional di Timor-Leste, masing-masing untuk pengembangan di dataran rendah dan dataran sedang. Kata kunci: karakterisasi, intensitas dormansi, persentase perkecambahan, mutu benih

Foxtail millet is a climate-resilient cereal crop that is growing in importance in food security and sustainable agriculture. This study aimed to identify panicle traits associated with yield, determine functional traits suitable for selecting high-productivity genotypes, and classify superior local Indonesian foxtail millet genotypes. Eight genotypes were evaluated using a randomized complete block design with three replications. Correlation analysis of 31 panicle traits revealed that grain filling rate, panicle weight, grain weight per panicle, grain weight per plant, and grain numbers on the middle and lower primary branches were positively associated with yield. Several of these traits also exhibited high broad-sense heritability and moderate GCV and PCV values, indicating their potential for selection. Principal component and two-way heatmap cluster analyses identified Buru, ICERI-7, Hambapraing, and Mauliru-2 as high-yielding genotypes. The findings provide critical insights for foxtail millet breeding programs in Indonesia focused on improving yield.

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.

Terap (Artocarpus elasticus Reinw. ex Blume) is an underutilized fruit tree native to Indonesia, valued both for its edible fruit and its diverse applications in traditional medicine. Terap seeds are recalcitrant, so cryopreservation is the most effective method for their long-term preservation. This study aimed to determine the optimal loading and vitrification times for cryopreservation to maintain seed viability. A factorial, completely randomized design was employed with two factors: loading time (0 and 20 min) and vitrification time (0, 30, and 60 min). Seed viability after loading and vitrification treatment with or without freezing in liquid nitrogen was evaluated using tetrazolium chloride (TTZ) and germination tests. Results indicated that the loading and vitrification treatments did not yet improve the viability of terap seeds after cryopreservation, as determined by the TTZ and germination tests. The TTZ test showed that the viability of all treated seeds decreased, regardless of whether they were frozen in liquid nitrogen. Germination tests revealed that all treated seeds without freezing had reduced germination, while none of the seeds treated with freezing germinated. Structural analysis indicated that freezing alters cell degradation, likely due to the formation of ice crystals and mechanical stress. To improve the success of terap seed cryopreservation, future efforts should focus on optimizing exposure times, reducing PVS2 toxicity, and enhancing cryoprotectant penetration by removing the seed coat or using the embryo axis as an explant.

Foxtail millet (Setaria italica L. Beauv.) is an emerging carbohydrate-producing crop. It is considered a climate-resilient crop due to its tolerance to abiotic stresses. Breeding for abiotic-tolerant crops requires powerful tools such as molecular markers. The single-nucleotide amplified polymorphism (SNAP) marker, developed from a single-nucleotide DNA variation at a specific location in the plant genome, is a simple yet powerful PCR-based marker widely used in phenotype-related selection. A SiDREB2-based SNAP marker was previously developed based on a base variation at the 558th base pair (an A/G transition) in the SiDREB2 gene and used to estimate the drought tolerance in foxtail millet. However, the specificity of the marker depends on technical aspects, including the type of DNA polymerase used, primer concentration, and the number of PCR cycles. Here, we reported that non-specific and false positive amplicons can be eliminated by utilizing DNA polymerase with no 3’ to 5’ proofreading activity and reducing the final primer concentration to 1.25 μM. PCR cycle number 25 yielded the optimum specificity, while increasing the cycle to 30 resulted in false positive results. Altogether, our results showed that technical optimization is necessary for improving the specificity of the SNAP marker.

The objective of this experiment was to study the response of rice genotypes to nitrogen under low temperature stress condition. This experiment was done at Sesean rural area, Tana Toraja Regency, South Sulawesi, 1500 m above sea level with mean temperature 18oC. Experiment was designed in Completely Randomized Block Design with two factors. The first factor comprised of 3 levels of Nitrogen dosage (0, 50, and 100 kg N / ha) and the second factor was cultivar i.e. Pulu' Mandoti, Pinjan, Lambau, Fatmawati, Sintanur and Gilirang. The results showed that at low temperature stress condition, nitrogen, cultivar and their interaction gave significant effect on percentage of pollen fertility, percentage of filled spikelet and weight of filled grain per spikelet, while interaction between nitrogen and cultivar did not significantly affect the flag leaf length and flowering date. Rice yield decreased with increasing N levels under low temperature stress condition. There were significant positive correlations between growth components (percentage of pollen fertility, flag leaf length and flowering date) and yield components (number of tiller and grain per panicle and weight of 1000 grain). Key words: low temperature stress, nitrogen fertilizer, rice, highland, pollen fertility

Aluminum (Al) toxicity and blast disease are the most important yield-limiting factors for upland rice production in acid soils. The objective of this experiment was to examine the contribution of accumulation of Silicate (Si), Nitrogen (N) and Al in plant tissue on Al tolerance and blast disease resistance in upland rice. The experiment was arranged in a split-split plot design with 2 replications. Main plots were randomly assigned to blast treatment (control and inoculation to blast fungi). Subplots were assigned to control box (lime 1.5 AlEC) and another acid soils (no lime) box and sub-subplots were assigned to the tested genotypes. The result of the experiment showed that leaf blast disease resistance in rice cannot be solely explained by Si or N content in shoot tissue. The resistant to leaf blast disease might be attributed by high ratio Si/N weight in shoot. Al tolerance was ascribed by low reduction in root growth, high shoot dry weight, high Si content in shoot, and as well as high of Si/Al ratio in root. Key words: Al-tolerance, blast disease, upland rice, Si/Al ratio

Since physic nut (Jatropha curcas L.) is heterozygous, sexual propagation results in great genotypic and phenotypic variability. Development of efficient techniques for asexual propagation would benefit the nursery industry as this would lead to selection and production of particular clones with desirable characteristics. Therefore, two following studies were conducted from September until December 2007. The objective was develop a protocol for vegetative propagation of physic nut by stem cutting in different size of cutting. The first experiment was dealt with stem cutting length (20 cm, 25 cm, and 30 cm) at the same size of diameter (2.5-3.0 cm), and the second experiment was dealt with diameter of stem cutting (3 cm, 2.5-2.9 cm, 2.0-2.4 cm, and 1.5-1.9 cm) at the same size of length (30 cm). Each of experiment was designed in Completely Randomized Design with three replications. Each experimental unit consisted of 25 seedlings. The result showed that cutting growth varied depending on length and diameter of stem cutting. However, better seedling growth and better survival of young plant of physic nut can be obtained from stem cutting with 20-30 cm in length and stem cutting with 2.0-2.9 cm in diameter. Key words: cutting diameter, cutting length, Jatropha, survival, transplanting

Anther culture provides rapid route in obtaining pure lines in a single generation through producing green haploid plants that may be spontaneously doubled. This technique has been used for crop improvement especially in rice. The objective of this research was to determine regeneration ability of eight F1s derived from crossess between upland and new plant types of rice and from their four parents through anther culture. Completely randomized design with 25 replications was used in this research. Treatments consisted of four parent lines/varieties i.e. P1 (Fatmawati and BP360E-MR-79-2), P2 (Fulan Telo Gawa and Fulan Telo Mihat) and eight F1s obtained from reciprocal crosses of P1 and P2. Callus induction medium was based on N6 medium + 2.0 mg L-1 NAA + 0.5 mg L-1 kinetin + 10-3 M Putrescine, while regeneration medium was based on MS + 0.5 mg L-1 NAA + 2.0 mg L-1 kinetin + 10-3 M Putrescine. The result indicated that F1 derived from Fatmawati x Fulan Telo Gawa (5.00% green plants per total anther) and their reciprocal (3.80% green plants per total anther) crosses were the most responsive genotypes in rice anther culture (had high anther culture ability). The F1 genotypes were more effective to produce green and doubled haploid plants in rice anther culture than their parents. From this research, 161 double haploid plants (29.81%) from total acclimated green plantlets were obtained. Keywords: anther culture, upland rice, new plant type of rice
