Abstract

Massive conversion of agricultural land, especially on wetlands, has resulted in declining rice productivity, so extending cultivation to drylands is considered appropriate. However, limited water availability is a major constraint that cannot be ruled out, so the procurement of drought-adaptive high-yielding varieties is considered to be the most effective solution. The purpose of this study was to evaluate drought-tolerant mutant genotypes based on proline content and yield component characters at various percentages of water availability. The experiment was arranged using a factorial complete randomized design, the first factor is drought stress consisting of 100% field capacity (K3), 66% (K2), 33% (K1) and the second factor is genotype consisting of inpago unram (P1), MD200-G13-3-11-5 (P2), MD300-G20-8-3-5 (P3), MD200-G24-17-10-8 (P4), MD300-G27-16-9-5 (P5). The observed characters consisted of proline content, flag leaf length, panicle length, filled grain weight and hollow grain weight. The results showed that MD300-G27-16-9-5 (P5) is a mutant plant that has the greatest potential to obtain drought-tolerant traits, although the level of proline produced is not as high as Inpago Unram (P1) and MD200-G24-17-10-8 (P4), but the consistency of adaptation shown by MD300-G27-16-9-5 (P5) when experiencing drought stress tends not to cause a significant decrease in all yield component characters, namely flag leaf length, panicle length, filled grain weight and unfilled grain weight

Abstract

Food security and sustainability are facing challenges due to the increase in population and the large amount of dry land that has not been optimized for utilization. Rice cultivated in paddy fields is a problem that must be considered. The use of local varieties should be further studied because it is one of the efforts to increase plant productivity against drought stress. This study aims to assess the anatomical and physiological responses of M5 mutant G16 red rice from gamma irradiation to drought stress in the vegetative phase. The method used was experimental method with field experiments. The experiment was conducted from November 2023 to July 2024 at the Greenhouse of the Faculty of Agriculture, University of Mataram. The experimental design used was Faktorial Completely Randomized Design (CRD) with two factors, the first factor is drought stress consisting of 33% Field Capacity (K1), 66% Field Capacity (K2), 100% Field Capacity (K3) and the second factor is genotype consisting of Inpago Unram (P1), MD200-G13-18-16 (P2), MD300-G20-16-9-5 (P3), MD200-G24-17-10 (P4), MD300-G27-8-3-5 (P5). The result of this study show that MD200-G24-17-10 (P4) was the most responsive genotype to drought stress conditions in the vegetative phase. This was indicated by a decrease in stomatal density and chlorophyll content, as well as an increase in xylem diameter and stele diameter.

Abstract

Kedelai (Glycine max (L.) Merril) merupakan tanaman pangan palawija penting yang merupakan salah satu bahan baku industri pangan strategis di Indonesia. Akan tetapi, produktivitasnya masih tergolong rendah. Upaya yang dapat dilakukan dalam meningkatkan produktivitas tanaman kedelai adalah melalui perbaikan genetik antara lain menggunakan mutasi. Tujuan penelitian ini untuk mengetahui keragaman genetik karakter kuantitatif beberapa varietas kedelai generasi pertama hasil mutasi kimia Ethyl Methane Sulfonate. Penelitian ini dilaksanakan pada bulan Juli sampai Desember 2023 di Green House yang berlokasi di Kelurahan Tanjung Karang, Kota Mataram. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dua factor yang masing-masing diulang tiga kali. Faktor I adalah varietas (V) yang terdiri atas lima varietas: V1=Detam-2, V2=Anjasmoro, V3=Burangrang, V4=Dega-1, V5=Dering. Faktor II adalah konsentrasi penggunaan mutagen kimia EMS (E) yang terdiri atas E0= 0% EMS, E1=0,5% EMS, E2=1% EMS. Data hasil pengamatan selanjutnya dianalisis menggunakan analisis variansi (ANOVA) yang dilanjutkan dengan analisis keragaman genetik dan heritabilitas arti luas melalui perhitungan ragaman genetic dan ragam fenotipik. Hasil penelitian menunjukkan bahwa koefisien keragaman genetic (KKG) karakter kuantitatif kedelai mutan kimia generasi pertama yang tergolong tinggi adalah tinggi tanaman (24,9%), jumlah cabang (84,8%), umur berbunga (23,7%), jumlah biji per tanaman (59,6%), dan bobot 100 biji (37,4%). Sedangkan nilai duga heritabilias arti luas yang tergolong tinggi adalah jumlah cabang (0,8), jumlah buku (0,6), berat kering tajuk (0,5), Panjang akar (0,8), berat kering akar (0,7), umur berbunga (0,7), jumlah polong (0,6), polong hampa (0,8), jumlah biji per tanaman (0,7), berat biji per tanaman (0,8), bobot 100 biji (1).

Abstract

Rice bean is a group of beans that are rich in carbohydrates, proteins and fats. This plant is resistant to pests and diseases, as well as the broad adaptability. This study aims to obtain an efficient fertilization pattern on rice bean cultivation in dry land. The treatments consisted of 9 fertilization patterns which were RP0: no fertilizer (control); RP1: 100% recommendation fertilizer (50 kg Urea and 100 kg SP-36 ha-1); RP2: 5 Mg ha-1 manure plus 50% recommendation fertilizer; RP3: RP2 plus MVA; RP4: 5 Mg ha-1 Crotalaria sp compost plus 50% recommendation fertilizer; RP5: RP4 plus VAM; RP6: 2.5 t ha-1 manure, 2.5 Mg ha-1 Crotalaria sp compost plus 50% recommendation fertilizer; RP7: 1.5 Mg ha-1 manure, 1 Mg ha-1 Crotalaria sp compost plus 50% recommendation fertilizer; RP8: RP7 plus MVA. Fertilization treatments were arranged in RCBD and each treatment was repeated 3 times. The fertilization treatments had no significant effect on NUE. Productivity of rice bean in RP3 and RP5 reached 3.75 Mg ha-1, in RP2 and RP4 achieved 2.64 Mg ha-1, and in the control treatment reached 1.94 Mg ha-1. Carbohydrate content in seeds increased by 20% in the fertilization treatments compared to the control. Protein and anthocyanin content in all treatments were not significantly different. The combination of 5 Mg organic fertilizer (manure and / or Crotalaria compost), 50% recommendation fertilizer plus MVA was an efficient fertilization pattern to improve P fertilizer uptake efficiency (PUE), productivity and quality of rice bean crop in dry land.
