The study was carried out with twenty-four genotypes of rice during the Spring season, 2020 in Hanoi, Vietnam in order to exploit the attributes and divergence of quality properties from existing rice cultivars in North Vietnam. The rice genotypes were characterized based on ten quality parameters of milling, physical appearance and physiochemical characters using Mahalanobis D2 statistic

In the Western world bovine milk products are an important protein source in human diet. The major proteins in bovine milk are the four caseins (CN), αS1-, αS2-, β-, and k-CN and the two whey proteins, β-LG and α-LA. It has been shown that both the amount of specific CN and their isoforms including post-translational modifications (PTM) influence technological properties of milk.

Bovine milk provides important minerals, essential for human nutrition and dairy product quality. For changing the mineral composition of the milk to improve dietary needs in human nutrition and technological properties of milk, a thorough understanding of the genetics underlying milk mineral contents is important.

Most traits targeted in the genetic improvement of hop are quantitative in nature. Improvement based on selection of these traits requires a comprehensive understanding of their inheritance. This study estimated quantitative genetic parameters for 20 traits related to three key objectives for the genetic improvement of hop: cone chemistry, cone yield and agronomic characteristics.

The research has designed a novel active truck seat suspension system for a further study of active vibration control. A 5-degree-of-freedom driver and seating suspension system model for active vibration control has been developed. A novel fast system parameter identification method from vibration measurement data has been proposed for the seat-occupant system based on the multi-objective Genetic Algorithm optimization (GA).

This study was conducted to estimate genetic relationships among banana clones growing in Turkey via some morphological parameters and two molecular marker systems. In terms of yield parameters such as bunch weight, hand number, fruit weight, and total fruit number, Grand Nain (GN) clone came to the forefront with the highest values. It was followed by Azman (AZ), Dwarf Cavendish (DC), and Erdemli Yerli (EY) clones, respectively.

Semen traits are important for the widespread use of superior bulls. Thus, the objective of this study was to estimate the heritability of five semen traits, ejaculate volume (VE), progressive sperm motility (SM), sperm concentration (SC), number of sperm (NSP), and number of progressive motile sperm (NMSP), and their genetic correlations (rg).

Reproductive performance is critical for efficient swine production. Recent results indicated that vulva size (VS) may be predictive of reproductive performance in sows. Study objectives were to estimate genetic parameters, identify genomic regions associated, and estimate genomic prediction accuracies (GPA) for VS traits.

Polygenic risk scores (PRSs) have wide applications in human genetics research, but often include tuning parameters which are difficult to optimize in practice due to limited access to individual-level data. Here, we introduce PUMAS, a novel method to fine-tune PRS models using summary statistics from genome-wide association studies (GWASs).

Drought is a major threat to wheat production worldwide and development of drought-tolerant wheat genotypes may improve the production of this cereal crop in drought affected regions. In the present study, 24 mutant lines were developed by treating a wheat variety ‘NN-Gandum-1(NN-1) with ethyl methane sulfonate (EMS). The M5 , M6 , and M7 generations were evaluated for quantitative traits under well irrigated and rainfed conditions. Furthermore, best performing mutants of M6 and M7 generations were examined for biochemical parameters.

Understanding the consequences of thermal and chemical variations in aquatic habitats is of importance in a scenario of global change. In ecology, the sex ratio is a major population demographic parameter. So far, research that measured environmental perturbations on fish sex ratios has usually involved a few model species with a strong genetic basis of sex determination, and focused on the study of juvenile or adult gonads. However, the underlying mechanisms at the time of gender commitment are poorly understood.

Despite the health concerns and nutritional importance of fatty acids, there is a relative paucity of studies in the literature that report genetic or genomic parameters, especially in the case of sheep populations. To investigate the genetic architecture of fatty acid composition of sheep, we conducted genome-wide association studies (GWAS) and estimated genomic heritabilities for fatty acid profile in Longissimus dorsi muscle of 216 male sheep.

In the present study, it is clear that it is possible to develop high yielding lines with high quality traits with superior nutritional features. The parameters have indicated sufficient variability for different nutritional characters, so that it would enable the breeder to utilize appropriate genetic resources in the crossing programme to improve the particular character.

This research proposes a new Hybrid Meta-heuristic model which is a combination of Ant Colony Optimization algorithm (ACO), Bacterial foraging algorithm (BFA), and Pair-Wise Exchange Heuristic algorithm (PWEH). The proposed algorithm is named Dynamic Hybrid Ant Colony Algorithm (DHACA) model that can enhance local and global searches simultaneously. In addition, parameter values are optimized to create a better solution.

This study describes a promising method for understanding how halophytes adapt to extreme saline conditions and to identify populations with greater resistance. Image and colour analyses have the ability to obtain many image parameters and to discriminate between different aspects in plants, which makes them a suitable tool in combination with genetic analysis to study the plants salt tolerance.

Correlation studies would provide estimates of degree of association between grain yield and its various components and also among the components. While, path co-efficient analysis further elucidates the intrinsic nature of association of component traits by determining direct or indirect contribution of these traits to yield (Baldaniya et al, 2018).
