Performance Test of Vegetative Characteristics of Crossed Rice (Oryza sativa L.) Lines of Ciherang Variety X B11143D Line in Telagasari, Karawang Regency, Indonesia

One way to increase the genetic diversity of Ciherang as the superior variety is to cross Ciherang with the donor B11143D line as a New Plant Type (NPT) rice. This study aimed to obtain Ciherang X B11143D lines with the best vegetative characteristics in the field. The research was conducted in rice fields in Talagasari Village, Telagasari District, Karawang Regency, from May to September 2023. This experiment used a single-factor Randomized Block Design (RBD) with three replications of 22 treatments, consisting of 19 Ciherang X B11143D lines and three comparison varieties. The effect of treatment was studied using analysis of variance. The results showed that the rice lines significantly influenced the vegetative characters of Ciherang X B11143D lines in Telagasari, Karawang Regency. Based on the observed characters, several lines were selected i.e. 124.2.3, 94.3.3, and 20.4.4 lines. Those three lines chosen as backcrossing lines performed similarly compared to Ciherang as recurrent parent and inherited several important traits for rising productivity from the B11143D line as donor parent, namely the length and area of flag leaf, the total number of tillers, and the number of productive tillers, which were significantly higher than Ciherang.

Operation of a Pilot-Scale Biogas Plant Made of Textile Materials and Application of Its Results to a Full-Sized Demonstration Plant

In small German farms, there is a technically usable potential of cattle manure and pig manure ranging from 153 to 187 million tons of fresh matter per year. Since 2021 and 2023, new incentives under the Renewable Energy Sources Act (EEG) have been promoting biogas production in small farms. These incentives, applicable to biogas plants up to 150 kWel, include direct compensations for plants up to 100 kWel and market premiums for those up to 150 kWel. A small biogas plant made of textile materials was designed for both pilot and full-scale applications. Compared to conventional concrete biogas reactors, these textile-based reactors offer a simplified construction and operation, eliminating the need for specialized civil engineering. The primary objective of this research is to demonstrate the process engineering feasibility of biogas reactors based on textile materials for small farm biogas plants (30 to 75 kWel). Another goal is to design the construction method in such a way that this type of system can be built by farmers themselves after type testing on site. Operational insights were gathered from the laboratory plant with a 300-L digester volume, using cattle manure and clover grass silage. To adapt the system to the biogas reactor made of textile materials, the reactor was designed without a stirrer. These insights were considered in the design and approval procedure of the full-sized demonstration biogas plant made of textile materials. The full-size demonstration plant digesters underwent an approval procedure from local authorities, featuring treatment volumes of 120 m3 for the main biogas reactor and 550 m3 for the digestate reactor in an earth basin style. This new type of biogas plant could be built in small farms for self-sufficiency in electrical and thermal energy or for treating sewage sludge in small-scale communal wastewater treatment and biogas plants.

GENETIC ARCHITECTURE OF NEW PLANT TYPE RICE (ORYZA SATIVA L.) LINES BASED ON A 12-YEARS MULTI-EXPERIMENT

New plant-type (NPT) rice can increase grain yield globally. Although many studies have shown the association between harvest and yield-related traits in rice, it remains obscure in the case of NPT rice. This study aimed to elucidate the relationship between agronomic and yield features in new plant-type rice based on a 12-years multi-experiment. A large dataset of 704 NPT rice lines of various generations (F4 to F10), derived from 24 different populations, underwent study. The analysis of variance showed a highly significant population effect (P < 0.01) on all traits studied. The NPT rice populations had groupings into four clusters, with a highly substantial cluster effect (P < 0.01) on the number of total tillers (NTT), number of total grains (NTG), number of filled grains (NFG), and thousand-grain weight (TGW). Standard best NPT lines from each experiment achieved an average of 1.67 t ha-1 or 26% higher yield than the Ciherang variety. Determining the yield advantage of NPT lines was by higher plant height (PH) (r = 0.37), panicle length (PL) (r = 0.15), NTG (r = 0.28), NFG (r = 0.28), TGW (r = 0.10), and lower days to harvest (DTH) (r = -0.10). The principal component analysis biplot revealed that NFG could better serve as a selection characteristic for enhancing grain yield in developing NPT rice adapted to irrigated tropical ecosystems.

Stability analysis, agronomic performance, and grain quality of elite new plant type rice lines (Oryza sativa L.) developed for tropical lowland ecosystem

Rice is a major world staple food crop, and therefore breeding improved varieties is of ultimate importance. Genotype-by-environment analyses are essential to understand the potential performance of the lines over environments. This study aimed to elucidate the stability, agronomic performance, and grain quality of elite new plant type (NPT) rice lines developed for tropical lowland areas. Elite NPT rice lines were evaluated in eight locations along with national varieties as checks. Combined analysis across environments and several stability analyses were performed. The results revealed the possibility of breeding high-yielding NPT rice varieties with different stability profiles, namely broad adaptation (IPB189-F-13-1-1 (G5), bi = 0.91), suited for favorable environments (IPB187-F-37-1-2 (G1), bi = 1.47), and adapted to marginal environments (IPB193-F-30-2-1 (G9), bi = 0.54). G1 and G5 belonged to different groups of grain characteristics, each with low and high amylose content, respectively. The highest yielding line (IPB189-F-23-2-2 (G6), 8.68 ton ha−1) had an advantage of 19.39% over the highest yielding check, i.e., Inpari 32 (7.27 ton ha−1). This increase in yield was contributed by the success of breeding with a greater 1000-grain weight (11.91%) and number of filled grains per panicle (42.37%) than Inpari 32; meanwhile, the plant height also increased by 19 %. In addition, the rank correlations among three stability parameters, sdi2, Wi2, and σi2 were positive and highly significant. This study enlightens the prospect of breeding NPT rice varieties with different adaptations in tropical lowland areas.

Pendugaan Ragam Genetik dan Heritabilitas Beberapa Genotipe Padi Tipe Baru (PTB)

This study aims to determine the genetic variance and heritability of yield component and agronomic character of some new plant type (NTP) of rice genotypes planted on two different locations. The research was arranged in randomized complete block design (RCBD) with 12 treatments and three replications as a blok was nested in location (in two locations, i.e.: East Lampung and Tanggamus. The treatment consisted of 10 new type of rice genotypes, i.e.: IPB 3S, IPB 4S, IPB 5R, IPB6R, IPB117-F-7-2-1, IPB 117-F-7-7- 1, IPB 117-F-14-4-1, IPB 117-F-15-4-1, IPB 117-F-20-1-1, IPB 117-F-80- 2-1, and two control varieties, i.e.: Ciliwung and Ciherang. The flowering time, harvesting time, percent of filled grain per panicle, weight of 1000 grains, dray weight of plant, and yield potential have large genetic variability. Plant height, number of tillers, number of productive tillers, flowering time, harvesting time, panicle length, number of filled grain per panicle, number of grain sterility per penicle, percent of filled grain per penicle, weight of 1000 grains, weight of grain per panicle, and dry weight of plant have high heritability. Selection of NPT of rice genotypes was effective because its have wide genetic variability and can be done at an early stage in a character with high heritability.

Industrial Development Status and Prospects of the Marine Fuel Cell: A Review

In the context of the increasingly strict pollutant emission regulations and carbon emission reduction targets proposed by the International Maritime Organization, the shipping industry is seeking new types of marine power plants with the advantages of high efficiency and low emissions. Among the possible alternatives, the fuel cell is considered to be the most practical technology, as it provides an efficient means to generate electricity with low pollutant emissions and carbon emissions. Very few comprehensive reviews focus on the maritime applications of the fuel cell. Thus, news reports and literature on the maritime applications of the fuel cell in the past sixty years were collected, and the industrial development status and prospects of the marine fuel cell were summarized as follows. Some countries in Europe, North America and Asia have invested heavily in researching and developing the marine fuel cell, and a series of research projects have achieved concrete results, such as the industrialized marine fuel cell system or practical demonstration applications. At present, the worldwide research of the marine fuel cell focuses more on the proton exchange membrane fuel cell (PEMFC). However, the power demand of the marine fuel cell in the future will show steady growth, and thus the solid oxide fuel cell (SOFC), with the advantages of higher power and fuel diversity, will be the mainstream in the next research stage. Although some challenges exist, the SOFC can certainly lead the upgrading and updating of the marine power system with the cooperative efforts of the whole world.

An automatically configurable plant to produce electrolyzers

Due to the increasing importance of green hydrogen, the demand for electrolyzers, produced in lower-cost, automated series production, is rising sharply. Forecasts for estimating future market potential are characterized by a high degree of uncertainty in the type of electrolysis technology that will prevail. Depending on the circumstances, new types of adaptable electrolyzer production plants are needed, which are flexible in the type of electrolysis technology as well as in their throughput quantity. Thus, to produce electrolyzers economically, it is necessary to develop the production plant in parallel with the product. The challenge here is that those comprehensive automation concepts for electrolyzers production do not yet exist, and thus the production facilities must be conceptualized in parallel with a wide range of undefined electrolyzer products. This publication aims to answer the research questions: How can a flexible production plant for electrolyzers be conceptualized and digitally implemented? What does a methodical workflow look like to design and automatically configure production plants with the help of a limited number of electrolyzer input data? Starting from a reference electrolyzer, adaptable production plants were virtually commissioned to a proof-of-concept status. Thereby the plant is adaptable in throughput, it is easily expandable, and products with different electrolysis technologies and different dimensions can be served. In a subsequent evaluation, different plants are configured based on different requirements. Then, various production scenarios are simulated, and optimal configurations are determined. The customizable plant concept is the basis for a future plant configurator. Likewise, the proof-of-concept of the plant provides the basis for an iterative optimization process up to real commissioning, which is to be implemented as part of the H2Giga FertiRob research project.

SCoT markers assisted evaluation of genetic diversity in new plant type (npt) lines of rice

Rice being a stable food crop has wide range of diversity and distribution throughout the globe. Recently in hybrid rice breeding program new plant types have been developed through line x tester mating with the use of male sterility system. Genetic diversity and insight amplification among 43 New Plant Type (NTP) lines of rice using 15 start codon targeted polymorphism markers were tested. Out of 25 start codon targeted polymorphism (SCoT) primers, only 15 SCoT primers were amplified and produced 76 alleles with 83.26 per cent polymorphism. Average number of alleles per primer was 5.06, while polymorphism information content ranged from 0.28 to 0.67 with an average of 0.50 per primer. Dandogram cluster falls in two major group having 31 and 12 NPT lines respectively. Bangladesh J. Bot. 51(2): 335-341, 2022 (June)

Population Structure of a Worldwide Collection of Tropical Japonica Rice Indicates Limited Geographic Differentiation and Shows Promising Genetic Variability Associated with New Plant Type

Abating the approaching yield plateau in rice requires taking advantage of potential technologies that requires knowledge on genetic diversity. Hybrid breeding, particularly in indica rice, requires the recruitment of large genetic variability from outside because the available genetic diversity of the cultivated pool has already been utilized to a great extent. In this study, we examined an assembly of 200 tropical japonica lines collected worldwide for population genetic structure and variability in yield-associated traits. Tested along with 30 indica and six wild rice lines belonging to India, the tropical japonica lines indicated great phenotypic variability, particularly related to new plant type (NPT) phenology, and formed six clusters. Furthermore, a marker-based characterization using a universal diversity marker panel classified the genotype assembly into four clusters, of which three encompassed tropical japonica lines, while the last cluster included mostly indica lines. The population structure of the panel also revealed a similar pattern, with tropical japonica lines forming three subpopulations. Remarkable variation in the allelic distribution was observed between the subpopulations. Superimposing the geographical sources of the genotypes over the population structure did not reveal any pattern. The genotypes sourced closer to the center of origin of rice showed relatively little diversity compared with the ones obtained from other parts of the world, suggesting migration from a common region of origin. The tropical japonica lines can be a great source of parental diversification for hybrid development after confirming the presence of widely compatible genes.

Proposal of a Solar Thermal Power Plant at Low Temperature Using Solar Thermal Collectors

To this day, only two types of solar power plants have been proposed and built: high temperature thermal solar one and photovoltaic one. It is here proposed a new type of solar thermal plant using glass-top flat surface solar collectors, so working at low temperature (i.e., below 100°C). This power plant is aimed at warm countries, i.e., the ones mainly located between -40° and 40° latitude, having available space along their coast. This land based plant, to install on the seashore, is technologically similar to the one used for OTEC (Ocean Thermal Energy Conversion). This plant, apart from supplying electricity with a much better thermodynamic efficiency than OTEC plants, has the main advantage of providing desalinated water for drinking and irrigation. This plant is designed to generate electricity (and desalinated water) night and day and all year round, by means of hot water storage, with just a variation of the power delivered depending on the season.

The Role of Mutation Induction Technology in Forage Breeding

<p class="awteks">Mutation induction in breeding is one of many ways to improve the character of a plant, including forage crops. Formation of new variety of forage plants, especially grass is still very rare in Indonesia due to several obstacles, including the flower structure, ploid and reproductive systems of forage plants. Mutation induction in breeding as a method of producing new varieties of forage plants (grass and legume) can be utilized by eliminating the constraints in forage plants, because it can create new variety without being restricted by floral structure and reproductive system of plant. The paper aims to describe the mutation breeding and its methods on forage plants and its prospect to obtain new varieties of superior forage plants to meet the needs of forage in Indonesia. A number of factors, including mutation technique, mutagenic type, seed and other factors, are determining the success of mutational breeding. The creation of new types of forage plants by mutation-induction is aiming to increase productivity, improve forage performances and resist abiotic and biotic stress. Mutation breeding is expected to produce new varieties of superior forage plants in a relatively shorter time, because forage plants can be propagated in a vegetative or generative manner. It is epxected that the assembly of new varieties of forage plants can meet the needs of forage in quantity and quality.</p>

The meristem-associated endosymbiont Methylorubrum extorquens DSM13060 reprograms development and stress responses of pine seedlings.

Microbes living in plant tissues—endophytes—are mainly studied in crop plants where they typically colonize the root apoplast. Trees—a large carbon source with a high capacity for photosynthesis—provide a variety of niches for endophytic colonization. We have earlier identified a new type of plant–endophyte interaction in buds of adult Scots pine, where Methylorubrum species live inside the meristematic cells. The endosymbiont Methylorubrum extorquens DSM13060 significantly increases needle and root growth of pine seedlings without producing plant hormones, but by aggregating around host nuclei. Here, we studied gene expression and metabolites of the pine host induced by M. extorquens DSM13060 infection. Malic acid was produced by pine to potentially boost M. extorquens colonization and interaction. Based on gene expression, the endosymbiont activated the auxin- and ethylene (ET)-associated hormonal pathways through induction of CUL1 and HYL1, and suppressed salicylic and abscisic acid signaling of pine. Infection by the endosymbiont had an effect on pine meristem and leaf development through activation of GLP1-7 and ALE2, and suppressed flowering, root hair and lateral root formation by downregulation of AGL8, plantacyanin, GASA7, COW1 and RALFL34. Despite of systemic infection of pine seedlings by the endosymbiont, the pine genes CUL1, ETR2, ERF3, HYL, GLP1-7 and CYP71 were highly expressed in the shoot apical meristem, rarely in needles and not in stem or root tissues. Low expression of MERI5, CLH2, EULS3 and high quantities of ononitol suggest that endosymbiont promotes viability and protects pine seedlings against abiotic stress. Our results indicate that the endosymbiont positively affects host development and stress tolerance through mechanisms previously unknown for endophytic bacteria, manipulation of plant hormone signaling pathways, downregulation of senescence and cell death-associated genes and induction of ononitol biosynthesis.

given the need to expand the range of medicinal plant raw materials presented in the pharmaceutical market of the Russian Federation, many authors are exploring new types of medicinal plants, including among crops traditionally considered food. In recent years, researchers have been interested in common peach leaves, which have a wide range of pharmacological effects. On the basis of peach extract, domestic scientists have proposed a number of biologically active additives, but due to the lack of modern regulatory documentation, raw peach leaves are not official today. The authors of the article conducted a comprehensive morphological and anatomical analysis aimed at developing the sections of normative documentation "External signs" and "Microscopy". The research was conducted in accordance with the requirements of the General Pharmacopoeia articles. Specific external features were identified, as well as microscopic features were identified.

Variation of Hull Over Grain Weight Percentage of Rice (Oryza Sativa L.) From Pakistan

Rice (Oryza sativa L.) is an important cash crop in the world. Rice is 2 nd most important food and cash crop of Pakistan after wheat. Forty accessions consisting of 20 conventional varieties and 20 New Plant Type (NPT) lines were used to determine percentage of hull over grain weight. The percentage of hull over grain weight was significantly different among varieties. The hull over grain weight percentage for varieties ranged from 10.5% to 30%. The percentage of hull /grain weight varied from 7.5% to 27.33 % for NPT lines and there was significant difference among NPT lines for this trait. This trait can be used in breeding program in order to increase rice production through increasing the milling efficiency by having thinner hull.
