1. Metabolomic and Histological Response of Passiflora cincinnata Infected with Cowpea aphid-borne mosaic virus (CABMV) Reveals Changes in Asymptomatic and Symptomatic Phases
Passion fruit woodiness disease, caused by the Cowpea aphid-borne mosaic virus (CABMV), is one of the leading phytosanitary challenges of passion fruit production. Passiflora cincinnata has been recognized for its potential in genetic improvement due to its highest resistance to CABMV and other phytopathogens. Metabolomic and histological alterations of P. c

2. Automated Counting of Meloidogyne javanica Galls in Vegetable Roots
RESUMO Os nematoides-das-galhas, gênero Meloidogyne spp., estão entre os parasitas mais destrutivos das plantas cultivadas. O sintoma mais característico da doença é o surgimento de galhas no sistema radicular. O uso da resistência genética é um dos mais eficientes, econômicos e menos impactantes do ponto de vista ambiental no controle desse endopar

3. Resistance of the wild tomato Solanum habrochaites to Phytophthora infestans is governed by a major gene and polygenes
Abstract: This work aimed to study the inheritance of resistance to Phytophthora infestans in tomato plants, using the maximum likelihood estimation function. The susceptible cultivar Santa Clara (Solanum lycopersicum) was used as the female genitor and the P. infestans resistant S. habrochaites f. glabratum accession (BGH 6902) as the male genitor.

4. Prospection of genetic resistance resources to root-knot nematodes in cucurbit genotypes
RESUMO O objetivo desse trabalho foi prospectar fontes de resistência aos nematoide-das-galhas em acessos de cucurbitáceas. Foram realizados dois experimentos, o primeiro para avaliar a resistência ao nematoide-das-galhas, M. incognita raça 1 em acessos das espécies Lagenaria vulgaris; Sicana odorífera; Cucurbita facifolia; Luffa sp.; Citrullus lanatus

5. Monitoring of Resistance of Sourgrass to Glyphosate Herbicide in Urban Areas of the State of São Paulo, Brazil
RESUMO: O objetivo deste estudo foi monitorar a resistência de Digitaria insularis ao glyphosate em áreas urbanas do Estado de São Paulo, visando a compreensão da disseminação dos biótipos resistentes. Para isso, foram realizados três experimentos em casa de vegetação no delineamento inteiramente casualizado com quatro repetições. No primeiro exp

6. Search for sources of resistance to Meloidogyne enterolobii in commercial and wild tomatoes
RESUMO Meloidogyne enterolobii (=M. mayaguensis) é um patógeno de plantas capaz de induzir galhas e reduzir produtividade de uma vasta gama de espécies hospedeiras. Este patógeno tem sido também reportado como ameaça global para a cultura do tomateiro (Solanum lycopersicum), principalmente, por causa da sua habilidade de suplantar a resistência a algu

7. Performance and selection of tomato cultivars for organic cultivation in greenhouse
ABSTRACT Production of tomato fruits in organic systems has difficulties such as the use of adequate cultivars. The hypothesis is that organic cultivation has strength dependency of the selection of appropriate genotypes to increase the economic viability of fruit production. The present work aimed to test and obtain, under organic greenhouse system, cultiva

8. Combinatorial analysis of agronomic characters in soybean
RESUMO A avaliação do potencial genético dos parentais é fundamental para obter populações superiores para os principais caracteres agronômicos. O objetivo desse trabalho foi obter estimativas das capacidades geral e específica de combinação de cinco genitores de soja, por meio do dialelo parcial, a fim de identificar os parentais e as combinaçõe

9. Resistance to Pratylenchus brachyurus in Vitis species population through multivariate approaches and mixed models
ABSTRACT: Genetically diverse interspecific hybrids of Vitis were selected for resistance to Pratylenchus brachyurus. Three segregating populations with 57 hybrid crosses were evaluated. The parents included Vitis romanetiiC166-043 × 07355-075, 06354-047 × Cereza and 06354-047 × Nocera, selected from the germplasm bank at the University of California, Dav

10. Phenotyping for angular leaf spot severity and its implication in breeding common bean for resistance
ABSTRACT: Phenotyping for severity of angular leaf spot (ALS) in common bean is important to identify new sources of resistance and select progenies in conventional and molecular marker-assisted breeding. In this study, three phenotyping methods for ALS severity were assessed and its implications in breeding for resistance to Pseudocercospora griseola are di

11. Development and validation of SNP assays for the selection of resistance to Meloidogyne incognita in soybean
Abstract This work aimed to develop and validate individual SNP molecular markers previously identified in a genetic association study of resistance to Meloidogyne incognita in soybean using a microarray panel. The markers identified in the array were converted in single TaqMan® markers. The single markers were used to create an SNP genotyping protocol and

12. Recurrent selection in common bean aiming at resistance to white mold in a greenhouse
Abstract The objectives of this study were to estimate the genetic progress of mass selection for white mold resistance in common bean, evaluated in a greenhouse in cycle XII of recurrent selection (900 S0 plants), and compare it with field selection in previous cycles. In addition, progress was compared with microsatellite marker-assisted selection (MAS) am
