1. Selection of ornamental peppers elite lines for ethylene-insensitive
ABSTRACT Peppers belongs to Capsicum genus and have a lot of different varieties. They can be different uses such as potted ornamental plants. Retail market for this type of pepper requires the development of a greater number of commercial cultivars with adequate ornamental characteristics as well as an extended shelf life (post-production). Ethylene exposur

2. Genetic divergence and combined selection for traits that provide high agronomic performance in common bean lines
ABSTRACT The selection of common bean lines with intermediate cycle, upright plant architecture and high grain yield is an important goal of breeding programs. This study proposes to examine the genetic diversity of common bean genotypes for agronomic traits, select superior genotypes for traits that provide high agronomic performance and define promising cr

3. Correlation and selection gains in F6 wheat genotypes
ABSTRACT The agronomic traits have complex quantitative inheritance, wheat breeding has a highly cost and time expending to achieve advanced lines, and new cultivars. The objective of this work was to estimate the phenotypic (rp), genotypic (rg) and environmental (re) correlation coefficients and the genetic parameters, as well as to estimate the selection g

4. Heritability of resistance to potato late blight in an F1 population of elite potato cultivars
ABSTRACT Phytophthora infestans is the most important disease in potato crops. Its control is based on the use of chemical products that have developed pathogen resistance and high economic and environmental impacts. To reduce these effects, the use of plant varieties or cultivars resistant to this pathogen has been proposed. The aim of this study was to eva

5. Selection of genotypes of peach rootstock resistant to Meloidogyne incognita
ABSTRACT The aim of this study was to evaluate the genotypes developed by the Peach Breeding Program at the Federal University of Viçosa, as regards to resistance to M. incognita. Six rootstocks genotypes propagated by cuttings (713-07, 713-13, 913-3, 913-6, 913-11 and 913-17) and two rootstocks propagated by seeds (‘Okinawa’ and hybrid between scion cu

6. GENETIC DIVERGENCE AND SELECTION OF COMMON BEAN CULTIVARS BASED ON PLANT ARCHITECTURE AND GRAIN YIELD
RESUMO A caracterização da divergência genética de cultivares de feijão para vários caracteres relacionados a arquitetura de planta e produtividade de grãos é inédita. Os objetivos desse estudo foram avaliar se cultivares de feijão de diferentes tipos de grãos diferem para 12 caracteres da arquitetura de planta e para produtividade de grãos, estu

7. Superiority index based on target traits reveals the evolution of Brazilian soybean cultivars over last half-century
ABSTRACT The objective of this work was to assess the breeding influences in different agronomic and physiological traits in Brazilian soybean cultivars, released between 1965 and 2011, to identify traits associated with modern cultivars. A total of 29 cultivars were evaluated in two locations in the 2016/17 crop season. Genotype selection based on agronomic

8. PREDICTIVE MODELS OF CHLOROPHYLL CONTENT IN SUGARCANE SEEDLINGS USING SPECTRAL IMAGES
ABSTRACT Chlorophyll content is a widely used parameter for nutritional status diagnosis in sugarcane. This study aimed to develop a predictive model of chlorophyll content in sugarcane seedlings using spectral imagery analysis within the electromagnetic spectrum visible range. The experiment was carried out in a split-plot design, with two fertilization rat

9. 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

10. Genome composition and pollen viability of Jatropha (Euphorbiaceae) interspecific hybrids by Genomic In Situ Hybridization (GISH)
Abstract Interspecific hybridization is required for the development of Jatropha curcas L. improved cultivars, due to its narrow genetic basis. The present study aimed to analyze the parental genomic composition of F1 and BC1F1 generations derived from interspecific crosses (J. curcas/J. integerrima and J. curcas/J. multifida) by GISH (Genomic In Situ Hybrid

11. Uni and multivariate approaches for diallel analysis in early generation trials for soybean tolerance to rust
ABSTRACT Due to the high impact of Asian soybean rust (SBR) in Brazilian croplands, several studies have been conducted in order to maintain or increase the grain yield gain over years in the presence of the pathogen. The aim of this study was to define a breeding strategy applying uni and multivariate approaches for diallel analyzes in early generation tria

12. Selection of Canadian potato clones for agronomic and frying quality traits
RESUMO A demanda por cultivares adequadas ao processamento industrial, principalmente na forma de palitos pré-fritos congelados, é crescente no Brasil. Sabe-se que a expertise canadense em relação ao desenvolvimento de cultivares com características de processamento é alta. No entanto, as condições de cultivo no Canadá são bastante diferentes das o
