Raspberries ( Rubus spp) are temperate climate fruits with profitable high returns and have the potential for diversification of fruit growing in mid to low-latitude regions. However, there are still no cultivars adapted to climatic conditions and high pressure of diseases that occurs in tropical areas. In this context, our objective was to evaluat...

Abstract Plant growth‐promoting bacteria (PGPB) may be of use for increasing crop yield and plant resilience to biotic and abiotic stressors. Using hyperspectral reflectance data to assess growth‐related traits may shed light on the underlying genetics as such data can help assess biochemical and physiological traits. This study aimed to integrate...

The asymmetric increase in average nighttime temperatures relative to increase in average daytime temperatures due to climate change is decreasing grain yield and quality in rice. Therefore, a better genome-level understanding of the impact of higher night temperature stress on the weight of individual grains is essential for future development of...

Recent technological advances in high‐throughput phenotyping have created new opportunities for the prediction of complex traits. In particular, phenomic prediction using hyperspectral reflectance could capture various signals that affect phenotypes genomic prediction might not explain. A total of 360 inbred maize (Zea mays L.) lines with or withou...

The asymmetric increase in average nighttime temperatures relative to increase in average daytime temperatures due to climate change is decreasing grain yield and quality in rice. Therefore, a better understanding of the impact of higher night temperature on single grain at whole genome level is essential for future development of more resilient ri...

The aim of this study was to conduct single-and multi-trait genome wide association studies (GWAS) and identify quantitative trait loci (QTLs) for the expression of phenotypic traits in Eucalyptus grandis. We evaluated an open-pollinated breeding population with 1772 genotypes composed of 25 different families established using a randomized complet...

Greenhouse‐based high‐throughput phenotyping (HTP) presents a useful approach for studying novel plant growth‐promoting bacteria (PGPB). Despite the potential of this approach to leverage genetic variability for breeding new maize (Zea Mays L.) cultivars exhibiting highly stable symbiosis with PGPB, greenhouse‐based HTP platforms are not yet widely...

Machine learning methods such as multilayer perceptrons (MLP) and Convolutional Neural Networks (CNN) have emerged as promising methods for genomic prediction (GP). In this context, we assess the performance of MLP and CNN on regression and classification tasks in a case study with maize hybrids. The genomic information was provided to the MLP as a...

Unlabelled: Exploring the symbiosis between plants and plant growth-promoting bacteria (PGPB) is a new challenge for sustainable agriculture. Even though many works have reported the beneficial effects of PGPB in increasing plant resilience for several stresses, its potential is not yet widely explored. One of the many reasons is the differential...

Usually, the comparison among genomic prediction models is based on validation schemes as Repeated Random Subsampling (RRS) or K-fold cross-validation. Nevertheless, the design of training and validation sets has a high effect on the way and subjectiveness we compare models. Those procedures cited above have an overlap across replicates that might...

One use of soybean [Glycine max (L.) Merr.] as food is in the form of vegetable, also known as Edamame, in which the green pods with seeds fully developed are harvested and consumed after a brief cooking. Until now, few efforts have been devoted to developing new soybean cultivars with high agronomic performance and characteristics suitable for hum...

Asian soybean rust (ASR) is one of the most important diseases in soybean and is responsible for large economic losses. However, the use of tolerant genotypes is a sustainable strategy to address this issue. The aims of this study were to evaluate the tolerance to ASR across agronomic traits and to characterize the genetic control of the tolerance...

Due to the high impact of Asian soybean rust (SBR) in Brazilian croplands, several studies have been conducted in order to maintain or increase the grain yield gain over years in the presence of the pathogen. The aim of this study was to define a breeding strategy applying uni and multivariate approaches for diallel analyzes in early generation tri...

The cultivation of basil is worth mentioning, because it is a very promising crop. The aim of this study was to evaluate the development of the Basil cultivation, cultivar Tuscan lettuce leaf and Alfavaca red basilican, submitted to different doses of nitrogen. The first factor was composed of six nitrogen doses and one control (0, 40, 80, 120, 160...

Este livro descreve o uso da soja como hortaliça para alimentação humana. Focamos na caracterização e importância desse uso alternativo, bem como nas indicações técnicas para seu cultivo e , por fim, comercialização.

This research aimed to verify changes in associations between soybean traits in contrasting rust environments.

We aimed to access the genotype performance related to the level of tolerance and the Asian rust impact on soybean seed traits.
