Método de melhoramento por descendência de semente única, para obtenção de linhagens de feijoeiro resistentes ao crestamento bacteriano comum.

O objetivo do presente trabalho foi a obtenção de linhagens de feijoeiro comum resistentes aos crestamento bacteriano comum, utilizando-se o método de melhoramento por descendência de semente única. Foram obtidas 30 linhagens com resistência ao crestamento bacteriano comum e uma considerável diminuição do tempo para o avanço das gerações.

Caracterização e avaliação agronômica de novos isolados de rizóbio obtidos de nódulos de genótipos silvestes de feijoeiro-comum.

Este trabalho teve como objetivos avaliar a capacidade de utilização de fontes de C, tolerância à salinidade e temperatura, caracterizar genotipicamente e determinar a eficiência agronômica de novos isolados de rizóbio em condições de campo.

Promoção do crescimento de milho por novas estirpes de bactérias associativas: resultados de ensaios em rede conduzidos pelo instituto nacional de ciência e tecnologia da Fixação Biológica do Nitrogênio (INCT-FBN).

Foi implementada uma rede de ensaios pelo Instituto Nacional de Ciência e Tecnologia da Fixação Biológica do Nitrogênio (INCT-FBN) para a validação de novas estirpes de bactérias associativas com capacidade de promover o crescimento vegetal. A rede de ensaios formada abrange cinco estações experimentais, sendo quatro localizadas no Estado do Paraná e uma em Goiás.

Is there hope for BNF in common beans?

Although since 1984 there are Rhizobium strains available for common bean inoculation in Brazil, a survey in 2014 showed that only 15% of the Brazilian farmers adopt inoculation as a routine practice. Part of this disbelief in relation to common beans inoculation can be attributed to the fact that supposedly, bean inoculation would not be able to support increased yield levels in high-tech farms, being appropriate only for small farms. A series of demonstration units carried out since 2012, under farm conditions in the Cerrado region, have showed that a 10.8% mean increase in yield were obtained only with inoculation in relation to the treatment without inoculation and without nitrogen fertilization (whose average yield was 3163 kg ha-1). It was also found that inoculation with supplementation of 60 kg ha-1 of N promoted yield levels (4010 kg ha-1) higher than those with 120 kg ha-1 N as urea (3411 kg ha-1).

O que é e como fazer adubação verde.

Adubação verde é uma prática agrícola que consiste no uso de certas plantas que são capazes de reciclar os nutrientes presentes em camadas profundas do solo, ou na atmosfera, tornando o solo mais fértil e mais produtivo. Essas plantas são rústicas e têm sistema radicular forte.

Major loci controlling resistance to the angular leaf spot of common bean.

Based on the evidences presented in this paper, results from classical genetic studies, fine-mapping information and physical position analysis using the reference genome sequence of P. vulgaris, the BIC Genetic Committee has formally accepted the proposed new gene symbols.

Resistance to Fusarium wilt in common bean cultivars and lines in pre-commercial stage.

The objective of this study was to identify common bean cultivars with resistance to Fusarium wilt.

Phenotypic and molecular characterization of common bean genotypes for resistance to anthracnose.

This study aimed to perform phenotypic and molecular characterization of cultivars and breeding lines of common bean for resistance to anthracnose.

Cooking time of common bean: genetic parameters and selection of elite lines.

The objectives of this study were to investigate the genetic variability and select elite lines for CT, since these lines aggregate essential agronomic traits.

Progeny tests for common bean isolines resistant to diseases with the aid molecular markers.

The aim of this study was progeny tests in segregating populations for resistance genes to these three diseases.

Pyramided lines of "carioca" common bean and their reaction to Pseudocercospora griseola.

The present work aimed to characterize lines produced by the Breeding Program of Common Bean (PMGF) of the Federal University of Viçosa (UFV), called ?Ruda R3? and ?Pérola R1?, in reaction to different races of P. griseola.

Marker-assisted selection integrated to the embrapa common bean breeding program.

The establishment of a specific Marker-Assisted Selection Facility at the Embrapa Rice and Beans Biotechnology Laboratory, in 2014, has better supported the routine analysis with molecular markers demanded by the Embrapa Common Bean Breeding Program. In addition, it has also supported other Embrapa plant breeding programs, such as rice and cotton.

Productivity, adaptability and stability of production of special grain common bean lines in different environments of Minas Gerais, Brazil.

This study aimed to select special grain bean lines with high productivity, adaptability and stability of production, evaluated in different environments of the Minas Gerais State, Brazil.
