Using fuzzy logic to select coloured-fibre cotton genotypes based on adaptabili...

Cotton (Gossypium hirsutum L.) is the world’s leading natural textile fibre and is grown in over 60 countries, including Brazil, where it is an important agricultural commodity. The cultivation area currently covers approximately one million hectares in Brazil and has expanded into every region of the country, especially the Cerrado biome. Because of this expansion, it is necessary to analyse the influence of t...

Productivity and quality of cotton fiber in different planting seasons

Productivity and quality of cotton fiber in different planting seasons

Cotton is one of the main agricultural products produced in Brazil. With such a high demand in the market, it is necessary that the cotton cultivars present high productivity and fiber quality. In order to favor the expression of the potential of the genotypes, the cultivation must occur in climatic conditions that provide good development of the plants, being the sowing time a primordial factor for the good pe...

Selection of lineages, genetic parameters, and correlations between soybean cha...

Soybean has great economic importance in the world accordingly, this legume has been exploited in breeding programs aiming to provide cultivars with extensive grain yield, tolerant to pests and diseases, and adapted to different soil and climatic conditions. Therefore, the objectives of this work were to evaluate genetic parameters and correlations between soybean traits to select lineages to increase yield and...

Efeitos da aplicação de bioestimulantes em sementes de algodão

No Brasil a cultura do algodoeiro é uma das que mais utiliza tecnologia, surgindo a cada ano novas opções que auxiliam na produção, sendo o uso de bioestimulantes uma delas. O objetivo do presente trabalho foi avaliar o efeito do tratamento de sementes de algodoeiro com doses de biorreguladores na germinação e vigor das sementes. O experimento foi conduzido no Laboratório de Análise de Sementes da Universidade ...

Parametric and non-parametric analysis for determining the adaptability and sta...

The use of different evaluation methods of adaptability and stability in a breeding program is essential to obtain more accurate results of the lines that have been studied. The purpose of this research is to study the adaptability and stability of 25 soybean lines derived from the soybean breeding program, and for that, it was used parametric and non-parametric analysis at the Federal University of Uberlandia....

Diversidade fenotípica e molecular, correlações entre caracteres, adaptabilidad...

This study aimed to: a) assess the genetic diversity of soybean genotypes using agronomic traits and microsatellite markers b) assess the phenotypic and genotypic correlations between agronomic traits of soybean lines derived from different crosses, c) study interaction between genotype and environment and evaluate its effect on grain yield and d) evaluate the adaptability and stability of early and late soybea...

Parâmetros genéticos e variabilidade em genótipos de soja

Universidade Federal de Uberlândia; Mestre em Agronomia; A soja é a principal oleaginosa cultivada no mundo e tem sido grandemente melhorada, entretanto, grande parte dos processos de melhoramento não foi acompanhada de estudos de parâmetros e de variabilidade genética. O objetivo deste trabalho foi estudar a variabilidade genética entre genótipos F5 oriundos de 22 cruzamentos biparentais de soja, por meio de t...

Genetic variability among 79 soybean progenies from UFU-Breeding Program

Achieving high yield strains and early maturity are primary objectives in Soybean Breeding Program. As a result, the objective of this study was to evaluate 79 soybean progenies derived from ten biparental crosses from the Soybean UFU- Breeding Program. The experiment was conducted at Capim Branco Farm in Uberlândia, Minas Gerais. Initially the hibridation occurred among the parental genotypes with the desirabl...

BIOLOGIA DA REPRODUÇÃO DE Coffea arabica L. e Coffea canephora Pierre

O sucesso da cafeicultura deve-se, em parte, ao trabalho de melhoramento genético dessa cultura. No caso da cafeicultura brasileira, as cultivares atualmente cultivadas comercialmente produzem cerca de quatro vezes mais do que a primeira cultivar introduzida no país. E para se realizar o melhoramento, a primeira etapa é conhecer os mecanismos que estão envolvidos nesse processo. Daí a importância de se estudar ...
