Abstract

This study investigated the biomass productivity of sorghum main crop, first ratoon, and second ratoon. A randomized complete block design was employed for the main crop experiment, with eight sorghum genotypes (NS2-19, NS2-102, NS2-109, NS2-111, NS2-140, IPB 4, IPB 8, and “Numbu”) as the treatment factor. The ratoon crop was designed using a Split Plots Design with two treatment factors and three replications. The first factor was fertilizer treatment on the ratoon crops, with two levels: complete N, P, and K fertilizer (urea 133 kg.ha-1, KCl 100 kg.ha-1, and SP-36 100 kg.ha-1) and N fertilizer only (urea 133 kg.ha-1); this factor was arranged as the main plot. The second factor comprised eight elite sorghum lines, the same as those used in the main crop experiment, arranged as subplots. The results indicated that complete NPK fertilization and N fertilizer alone produced similar biomass productivity in sorghum ratoon crops. Among the genotypes, NS2-140 demonstrated the highest biomass productivity in the main crop, NS2-109 in the first ratoon, and NS2-19 in the second ratoon. The second ratoon exhibited the highest biomass yield compared to the main crop and the first ratoon.

Abstract

This research is a preliminary yield test of the F7 lines crossing from Numbu x Samurai 2. The aims are to obtain selection criteria, a relationship between vegetative characters and yield and biomass characters, and to obtain vegetative characters that have a direct influence on character Yield and biomass and have high production potential. This study used 20 F7 lines and 4 check lines grown using a Randomized Complete Block Design. The data were analyzed for variance and to estimate variance component analysis, broad sense heritability, genetic diversity coefficient, correlation analysis, cross-trace analysis, and selection index. The results showed that to obtain lines with high biomass, attention should be put on the characters of plant height, panicle diameter, and weight while selecting lines with high yields needs to pay attention tocharacters of the number of leaves at harvest and panicle weight. These characters show wide genetic variation, high broad sense heritability values, and have a high correlation and direct influence on biomass and yield. Therefore, they were potent selection criteria for sorghum plant breeding programs. The F7 lines selected for high biomass and yield based on the selection index were NS021, NS126, NS107, NS123, NS112, NS020, NS015, NS119, NS121 and NS011. Penelitian ini merupakan bagian dari uji daya hasil pendahuluan galur-galur F7 hasil persilangan Numbu x Samurai 2. Tujuannya adalah memperoleh kriteria seleksi hasil dan biomassa, memperoleh hubungan antar karakter vegetatif dengan karakter hasil dan biomassa, memperoleh karakter vegetatif yang berpengaruh langsung terhadap karakter hasil dan biomassa dan memperoleh galur sorgum yang memiliki potensi produksi tinggi. Penelitian ini menggunakan 20 galur F7 dan 4 galur pembanding yang ditanam menggunakan Rancangan Kelompok Lengkap Teracak. Data dianalisis ragam, analisis komponen ragam, heritabilitas arti luas, koefisien keragaman genetik, analisis korelasi, analisis sidik lintas dan Indeks seleksi. Hasil analisis menunjukkan bahwa untuk mendapatkan galur dengan biomassa tinggi perlu memperhatikan karakter tinggi tanaman, diameter dan bobot malai. Sedangkan seleksi galur dengan hasil tinggi perlu memperhatikan karakter bobot malai. Karakter-karakter tersebut menunjukkan ragam genetik yang luas, nilai heritabilitas dalam arti luas yang tinggi, dan mempunyai korelasi dan pengaruh langsung besar terhadap biomassa dan hasil, sehingga merupakan karakter seleksi yang sangat baik untuk program pemuliaan tanaman sorgum. Galur F7 yang terseleksi dengan biomassa dan hasil tinggi berdasarkan indeks seleksi adalah NS021, NS126, NS107, NS123, NS112, NS020, NS015, NS119, NS121 dan NS011.

Abstract

Kekeringan menyebabkan kerugian ekonomi pada usahatani cabai (Capsicum annuum L.) di Indonesia. Identifikasi kultivar cabai toleran kekeringan diperlukan sebagai langkah awal perakitan varietas cabai toleran kekeringan. Penelitian bertujuan mengidentifikasi perubahan morfo-anatomi beberapa kultivar cabai dan menetapkan tingkat toleransinya terhadap kondisi kekurangan air menggunakan ISK (Indeks Sensitivitas Kekeringan). Penelitian dilaksanakan di bulan Februari – Agustus 2022 di Badan Riset dan Inovasi Nasional (BRIN), Cibinong, Jawa Barat. Percobaan disusun berdasarkan Rancangan Kelompok Lengkap Teracak (RKLT) pola tersarang. Petak utama adalah kelembaban media (80% dan 35% kapasitas lapang). Anak petak adalah enam kultivar cabai. Hasil menunjukkan defisit air menyebabkan tanaman dorman, umur berbunga dan umur panen menjadi lebih lama, kerapatan trikoma meningkat, sedangkan peubah lain menurun. Penurunan pertumbuhan vegetatif dan tertundanya pembungaan (fenologi) mendahului penurunan hasil. SSP dan Genie ditetapkan toleran terhadap kondisi defisit air berdasarkan nilai ISK. Kata kunci: cekaman kekeringan, fenologi, indeks sensitifitas kekeringan, toleransi kekeringan

Abstract

Xanthomonas oryzae pv.oryzae merupakan salah satu bakteri patogen yang menyerang tanaman padi. Pengendalian terhadap penyakit ini telah banyak dilakukan dan salah satu teknik pengendalian yang dikembangkan saat ini melalui teknologi induksi ketahanan tanaman yang mengekspresikan gen PR-1. Penelitian kami untuk mendeskripsikan ekspresi gen PR-1 pada varietas padi IR64 yang terinduksi resistensinya oleh asosiasi antara bakteri endofit dan asam salisilat. Gen PR-1 dianalisis secara molekuler dan ekspresinya menunjukkan tanaman padi yang terinduksi resistensinya secara tunggal maupun kombinasi oleh kedua agens ini mem­perlihatkan adanya ekspresi protein PR-1. Ekspresi protein ini dipicu oleh aktivitas kedua agens penginduksi yang bekerja secara simultan untuk membentuk protein yang mampu menekan perkembangan penyakit ini. PR-1 bekerja sesuai dengan mekanisme dari masing-masing agens penginduksi resistensi tanaman. Varietas IR64 yang diketahui rentan terhadap penyakit hawar daun bakteri terbukti dapat ditingkatkan ketahanannya menjadi moderat.  Pemanfaatan induksi ketahanan tanaman melalui aktivitas kedua agens pengimbas yang membentuk protein PR-1 perlu dilanjutkan dengan inovasi formulasi teknik pengendalian yang diberikan secara simultan sebagai alternatif strategi pengendalian hawar daun bakteri maupun penyakit lainnya ke depan dengan pendekatan ramah lingkungan dan berkelanjutan.

Abstract

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

Abstract

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

Abstract

  Sorghum is one of high value commodities for food and energy security due to its wide adaptation. The objectives of this research were to study some genetic parameters of sorghum agronomic traits grown under acid soil conditions and to select aluminum-tolerant sorghum mutant lines.  The selection was conducted in an augmented design with 61 lines at the field research station of B2TP-BPPT Lampung. Genetic materials used were mutant lines developed throught gamma irradiation.  The results showed that there was significant differences among the mutant lines for  some agronomic characters observed.  The heritability estimates for agronomic characters were classified as intermediate to high.  Selection based on seed weight and biomass production resulted three best sorghum mutan lines i.e ZH30-29-07, ZH30-30-07, and ZH30-35-07.  These lines showed the best yield and biomass production under acid soil condition.   Key words:  sorghum, acid soil, heritability, selection

Abstract

Twenty seven land races of tropical japonica rice were test-crossed with a 'WA' type cytoplasmic male sterility (CMS) line IR58025A to evaluate their fertility restoration ability.  Based on pollen fertility and spikelet fertility of their F1 hybrids, genotypes are classified into maintainer or restorer.  The result showed frequency of maintainers among genotypes was higher than restorers.  Four genotypes, i.e., Ase Lapan, Ase Mandi, Hawara Bunar and Lampung Kuning were designated as maintainers.  These maintainers possess a number of desirable traits such as pest resistance and abiotic stresses tolerance; thus they will be useful for improving parental lines of hybrid rice.     Key words: Land race, test cross, fertility restoration

Abstract

Aluminum (Al) toxicity is the main yield-limiting factor for maize growing on acid soils of tropical regions. This experiment was conducted to screen maize (Zea mays L) genotypes under Al stress in culture solution. The experiment was arranged in a split plot design with three replications. The main plots were Al concentrations (0, 2.5, 5 10, 20, and 40 ppm Al), and the sub plots were 22 maize genotypes. The results indicated that the genotype AMATL-(HS).C2, SATP-(S2)-C6-S0, MRSS-1(S1).C1-29-1, and MRSS-1(S1).C1-57-1  were more tolerant to Al-toxicity than the other genotypes including Antasena. The growth of Al-tolerant genotypes under low concentration of Al (2.5 ppm Al) was stimulated. The Concentration of 5 - 10 ppm Al in nutrient solution was adequate to separate genotypes between tolerant and sensitive genotypes in screening maize genotypes under Al stress. Relative net root length and relative root length were the best variable to be used as Al-tolerance indicators.   Key words: Maize, Al-tolerance,   Al-toxicity
