1. Application of univariate and multivariate statistical analyzes in clonal selection of Eucalyptus spp. for charcoal production
Resumo O objetivo deste trabalho foi selecionar os materiais superiores de Eucalyptus spp. a partir de análises estatísticas univariada e multivariada. Utilizaram-se 25 materiais genéticos de Eucalyptus spp., coletados no município de Itamarandiba, Minas Gerais. Foram determinadas as propriedades da madeira e do carvão vegetal para todos os materiais ge

2. Adventitious rooting of cultivars and clonal selections of Prunus spp. rootstock under intermittent mist system
ABSTRACT To reduce peach tree losses due the Peach Tree Short Life (PTSL), the main research line in Brazil is to select tolerant rootstock and perpetuate it by cloning methods. The objective was to evaluate adventitious rooting capacity of softwood cuttings of three cultivars and several clonal rootstock selections of Prunus spp., under intermittent mist s

3. Mobile genetic elements associated with carbapenemase genes in South American Enterobacterales
ABSTRACT Introduction: Carbapenem resistance in members of order Enterobacterales is a growing public health problem causing high mortality in developing and industrialized countries. Its emergence and rapid propagation worldwide was due to both intercontinental spread of pandemic strains and horizontal dissemination via mobile genetic elements (MGE) such a

4. Andina - first clonal cultivar of high-altitude conilon coffee
Abstract Andina is a conilon coffee variety originated from a selection of clones discovered by farmers. It was cultivated and evaluated for yield and plant vigor an altitude of 850m asl. Five genotypes (A1, NV2, NV8, P1 and Verdim TA), with a mean yield of 51.3 bags per hectare per year.

5. Cashew crop propagation
Resumo Frutífera genuinamente brasileira, o cajueiro é conhecido principalmente devido à sua castanha e ao líquido da casca da castanha (LCC), amplamente utilizada na indústria. De grande importância alimentar, o pseudofruto também apresenta representatividade econômica no Brasil, apresentando, portanto, multifinalidade de cultivo. Com grande variab

6. Genetic parameters and selection of sugarcane in early selection stages for resistance to sugarcane borer Diatraea saccharalis
Abstract A T1 (sugarcane population originating from true seeds) and T2 (first sugarcane clonal stage) population were used to estimate genetic parameters and compare selection strategies for Diatraea saccharalis (Lepidoptera: Crambidae) resistance in sugarcane. In the T1 stage, heritability at the family mean level (h²=0.77) was higher than individual geno

7. Molecular marker assisted selection for increasing inbreeding in S1 populations of cassava
Abstract The objective of the present work was to use MAS in self-pollinated cassava populations for obtaining individuals with high inbreeding (f) aimed at rapid development of partial inbred lines. Three progenies (F0222, F1378 and F1662) were self-pollinated, generating a total of 233 S1 individuals. The progenies and the S1 individuals were evaluated in

8. METAHEURÍSTICA CLONAL SELECTION ALGORITHM PARA OTIMIZAÇÃO DO PLANEJAMENTO FLORESTAL
RESUMO Dada a importância de se avaliar novas tecnologias para otimização do planejamento florestal, este trabalho objetivou introduzir a metaheurística Clonal Selection Algorithm na resolução de um problema de ordenamento da produção florestal. Considerou-se uma área manejada de tamanho igual a 4.210 ha, contendo 120 talhões com idades entre 1 e 6

9. Allele dosage of PVY resistance genes in potato clones using molecular markers
Abstract Potato virus Y (PVY) is considered one of the most important pathogens in potato crop. The objective of this study was to estimate the allele dosage of Ry genes and select clones with multiple copies of resistance alleles to be used as parents in potato breeding programs. Seven clonal families were genotyped, including five parents with resistance t

10. Genetic parameters estimates and visual selection for leaves production in Ilex paraguariensis
ABSTRACT The selection of yerba mate superior genotypes, based on each plant leaf weight, is based on genetic parameters obtained from experimental plantations and it is practically impossible from the fourth year of age. Therefore, we estimate genetic parameters and check the feasibility of selection through notes and weight estimates of each tree at 18.5 y

11. Software Selegen-REML/BLUP: a useful tool for plant breeding
Abstract The software Selegen-REML/BLUP uses mixed models, and was developed to optimize the routine of plant breeding programs. It addresses the following plants categories: allogamous, automagous, of mixed mating system, and of clonal propagation. It considers several experimental designs, mating designs, genotype x environment interaction, experiments rep

12. Coffea arabica clones resistant to coffee leaf miner
Abstract Brazilian arabica coffee production is based on a set of highly productive cultivars sexually propagated. All of them are susceptible to coffee leaf miner, Leucoptera coffeella, and most of them are also susceptible to coffee leaf rust, Hemileia vastatrix. Aiming to reduce the selection process of cultivars with multiple resistances to both biotic c
