Persistence may be defined as high sustained yield over multi-harvest. Genetic insights about persistence are essential to ensure the success of breeding programs and any biomass-based project. This paper focuses on assessing biomass for bioenergy purpose 100 elephantgrass clones measured in six growth seasons Brazil. To assess clones' persistence, an index based random regression models genotype-ideotype distance was proposed. Results suggested existence wide genetic variability between...

Abstract A crucial point in agricultural experimentation is to compare treatments with high accuracy. However, prone field heterogeneity, and a common source of error the spatial variation between plots used an experiment. With plant breeding experiments, number tested genotypes requires breeders use large areas, which invariably increases likelihood variation. The models that do not address this can lead errors selecting best genotypes. Our goal was evaluate effects two models—first‐order...

In order to identify candidate genes that could be exploited marker-assisted selection in elephant grass, this study aimed investigate changes predictive accuracy using genomic relationship information simple sequence repeats eight traits (height, green biomass, dry acid neutral detergent fiber, lignin content, biomass digestibility, matter concentration) linked bioenergetics feeding.We...

Spatial trends represent an obstacle to genetic evaluation in maize breeding. analyses can correct spatial trends, which allow for increase selective accuracy. The objective of this study was compare the (SPA) and non-spatial (NSPA) models diallel multi-environment trial trials consisted 78 inter-populational hybrids, tested four environments (E1, E2, E3, E4), with three replications, under a randomized complete block design. SPA accounted autocorrelation among rows columns by inclusion...

In plant breeding, several multicategorical variables are evaluated using score scales that treated as interval scales. However, statistics use ratio operations, such the experimental CV and selection gain, only appropriate for data. Thus, this work aimed to propose strategies mitigate inconveniences faced in data analysis of scales, especially those involving gain obtained from different This proposes following strategies: (i) a standard scale with properties (ascending 0 point origin);...

The palm tree juçara (Euterpe edulis Mart) is considered one of the most important and threatened native species in Atlantic Forest. search for seeds Martius) has increased, generating a need technologies favorable to their production, quality conservation. aim this study was describe seed germination patterns 45 accessions by using nonlinear model examine behavior these select superior genotypes. After clustering into four groups, models, namely, logistic, Gompertz, von Bertalanffy Weibull...

RESUMO A palmeira Euterpe edulis é uma espécie nativa da Mata Atlântica e atualmente se encontra na lista das espécies ameaçadas de extinção. Uma alternativa para retirá-la desta seria o estímulo plantio comercial, focando manejo dos frutos, que recebem a classificação “superfruta” pelas suas propriedades químicas nutricionais. Entretanto, etapa extrema importância precede seleção genótipos superiores estudo associações entre as variáveis, pois permite traçar estratégias alternativas...

Abstract Potato ( Solanum tuberosum L.) is one of the most important crops for human consumption worldwide, representing an essential component food security several countries. However, yield and quality are negatively affected by biotic abiotic stresses. In this sense, selection potato cultivars tolerant to heat resistant diseases great importance. Our goal was select clones suitable chips industry, having tolerance bearing R x 1 Ry adg alleles, which confer resistance virus X Y . We...

Euterpe edulis is an endemic species of the Atlantic Forest that threatened by unsustainable exploitation palm heart. Fruit management alternative to overcome this problem, promoting income generation, preserving trees in forest remnants and motivating implementation farms for commercial production. In study, genetic diversity structure four natural populations E. were evaluated using microsatellite markers six morphological fruit traits, analyzed with without REML/BLUP method. The...

Pollen viability is essential for the sexual reproduction in plants.Genetic and environmental factors as well plant age can influence this characteristic.In work, pollen was studied guava (Psidium guajava L.), a cross-pollination species.The genetic parameters characteristic were estimated considering 22 genotypes, two environments different ages.For that, of genotypes evaluated three years (2013, 2014 2015) experimental orchards (installed randomized block design, with blocks plants per...

Abstract The performance of inbred lines in advanced endogamous generation is commonly evaluated successive generations testing and selection, which we defined as “multistage field trials” (MSFT). MSFT data routinely exhibit heterogeneity (co)variances at several levels due to genetic and/or statistical imbalance. Nowadays, mixed models have been widely used deal with unbalanced data. However, few studies on common bean addressed the use a model approach modeling (co)variance structures for...

Because of its wide distribution, high yield potential, and short cycle, the potato has become essential for global food security. However, complexity tetrasomic inheritance, level heterozygosity parents, low multiplication rate tubers, genotype-by-environment interactions impose severe challenges on tetraploid potato-breeding programs. The initial stages selection take place in experiments with accuracy many quantitative traits interest, example, tuber yield. goal this study was to...
