The genetic determinism of the calving and suckling performance of beef cows is little known whereas these maternal traits are of major economic importance in beef cattle production systems. This paper aims to identify QTL regions and candidate genes that affect maternal performance traits in the Blonde d’Aquitaine breed.

Most agronomical traits of crop species are complex traits controlled by multiple genes and affected by environmental factors. While considerable efforts have been made to fine-map and clone major quantitative trait loci (QTLs) for yield-related traits in rice, it is not until recently that the attention has been paid to minor QTLs.

Due to the lack of statistical power and confounding effects of population structure in human population data, genotype-environment interaction studies have not yielded promising results and have provided only limited knowledge for exploring how genotype and environmental factors interact to in their influence onto risk.

Testing gene-gene interaction in genome-wide association studies generally yields lower power than testing marginal association. Meta-analysis that combines different genotyping platforms is one method used to increase power when assessing gene-gene interactions, which requires a test for interaction on untyped SNPs.

Increasing grain yield is a primary objective of maize breeding. Dissecting the genetic architecture of grain yield furthers genetic improvements to increase yield. Presented here is an association panel composed of 126 maize inbreds (AM126), which were genotyped by the genotyping-by-sequencing (tGBS) method.

Productivity of cowpea [Vigna unguiculata (L.) Walp] in sub-Sahara Africa is curtailed by a lack of farmer-preferred and improved cultivars and modern production technologies. The objectives of the study were to determine the extent of genetic diversity present among a collection of cowpea accessions from Zambia and Malawi using phenotypic traits and single nucleotide polymorphism (SNP) markers and, to select distinct and complementary parental lines for cultivar development.

High-throughput/high-content microscopy-based screens are powerful tools for functional genomics, yielding intracellular information down to the level of single-cells for thousands of genotypic conditions. However, accessing their data requires specialized knowledge and most often that data is no longer analyzed after initial publication.

The main diseases of wheat (Triticum aestivum L.) in Egypt, causing up to 50% of yield losses. Genetic resistance is the most economic and effective means of reducing yield losses caused by the disease. However, breeding genotypes for disease resistance is a continuous process and plant breeders need to add new effective sources to their breeding materials.

Fungal and bacterial rhizosphere microbiome associated with selected melon and snake melon genotypes
The total bacterial population in the rhizosphere of ten melon and two snake melon genotypes was significantly 59 to 68% higher than control soil. For most tested genotypes, a significant increase in the culturable rhizospheric actinomycetes, about 28.5 to 92.6%, was recorded comparatively to control soil. Fungal population counts in the rhizosphere of tested genotypes were significantly comparable to control.

This study was carried out in Mediterranean climate and under rainfed conditions in Turkey for a period of three years throughout the growing seasons of 2014/2015, 2015/2016 and 2016/2017. It was conducted in a randomized complete block experimental design (RCBD) with three replications. In present study, genetic diversity for agro-morphological characters and macro/microelements were investigated in sixteen promising local faba bean genotypes originated from Turkey. According to the results of the study, mean grain yield varied from 2320 kg ha–1 (Tekirdağ-39) to 3130 kg ha–1 (Burdur-50).

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.

Mustards occupy an important place among oilseed species due to their considerable economic and nutritional value and multiple uses. This study made use of 77 mustard genotypes collected from the USDA gene bank and diverse ecologies of Turkey to determine the extent of morphologic variability among them. The genotypes were screened to select genotypes appropriate for use in mustard breeding programs during 2015–16 and 2016–17 under the Mediterranean rainfed conditions of Yenimahalle (spring sowing and autumn sowing) and Haymana (spring sowing).

Proso millet (Panicum miliaceum L.) has many favored nutritional and agronomic traits, which makes it appropriate for cultivation and consumption all around the world. Genomic resources for proso millet are still very limited but the set of genomic data is improving. In this study, we genotyped six Slovenian landraces of proso millet (P. miliaceum L.) along with one Slovene autochthonous cultivar, Sonček. The chosen set of 11 SSR markers showed that there is low overall heterozygosity (0.561) among Slovenian landraces of proso millet.

There is great potential for the genetic improvement of oil palm yield. Traditional progeny tests allow accurate selection but limit the number of individuals evaluated. Genomic selection (GS) could overcome this constraint. We estimated the accuracy of GS prediction of seven oil yield components using A × B hybrid progeny tests with almost 500 crosses for training and 200 crosses for independent validation. Genotyping-by-sequencing (GBS) yielded +5000 single nucleotide polymorphisms (SNPs) on the parents of the crosses.

Gossypium barbadense (Sea Island, Egyptian or Pima cotton) cotton has high fiber quality, however, few studies have investigated the genetic basis of its traits using molecular markers. Genome complexity reduction approaches such as genotyping-by-sequencing have been utilized to develop abundant markers for the construction of high-density genetic maps to locate quantitative trait loci (QTLs).

Quantum of genetic variability and the extent to which heritable and nonheritable variations are related to the characters, determines the extent of genetic amelioration. The present investigation was carried out in kharif, 2019 to understand the clustering pattern and correlation for yield attributing traits in aromatic landraces of rice. Here 90 aromatic rice landraces along with six check varieties were evaluated for 10 quantitative characters. Cluster analysis divided these 96 rice genotypes into 4 clusters.
