1. Number of experiments necessary to more accurately differentiate common bean genotypes for grain physical traits and minerals in cluster analysis
ABSTRACT The number of experiments that provides greater detail in the differentiation of common bean genotypes for grain physical traits and minerals in cluster analysis is not known. This study was undertaken to determine the number of experiments necessary to more accurately differentiate common bean genotypes for grain physical traits and minerals in clu

2. Genetic variability in Capsicum spp. accessions through multicategorical traits
ABSTRACT Capsicum peppers originate from the American continent. Their culinary and medicinal potential, first exploited by indigenous peoples over 7000 years ago is vast, however more studies are needed. Despite the existence of germplasm banks that house hundreds of accessions of the genus, only a little of this diversity is seen in large markets. In this

3. 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

4. THE USE OF GENETIC DISTANCE AND GROUPING METHODS TO PREDICT Eucalyptus Pellita F. MUELL GENITORS FOR HYBRIDIZATION
ABSTRACT The objective of this study was to use quantitative traits to estimate the genetic distance among E. pellita provenances and progenies, to inform possible hybridization strategies in a species improvement program. A provenance and progeny test with 118 progenies from seven provenances was evaluated. The following quantitative traits were measured at

5. Image phenotyping of lettuce germplasm with genetically diverse carotenoid levels
ABSTRACT Developing biofortified foods such as lettuce is a frequent goal of breeding programs. One obstacle to the success of these efforts is the high temporal and financial cost of determining leaf constituents. Image phenotyping has been increasingly used in crop breeding, but not in lettuce breeding. Until now, the use of image phenotyping to indirectly

6. Genetic diversity in F3 population of ornamental peppers (Capsicum annuum L.)
ABSTRACT Peppers belong to the Solanaceae family and present a wide genetic variability that may be accessed through phenotypic and genotypic traits. This work aimed to study the genetic divergence in an ornamental pepper F3 population by multivariate methods based on the individual and simultaneous analyses of qualitative, quantitative, and molecular data.

7. Evaluation of production and quality traits in interspecific hybrids of ornamental pepper
RESUMO O cultivo de pimentas em vaso como planta ornamental tem aumentado consideravelmente em todo o planeta. No Brasil, esse cultivo é mais recente e ainda carece de cultivares. Para ampliar a variabilidade disponível e obter novas cultivares, a hibridação interespecífica é muito útil como forma de inserir um atributo desejável que ocorre em uma es

8. Genetic diversity among red mombin fruits in the Southwest of Goiás
ABSTRACT The identification of productive plants with fruits of desirable characteristics contributes to the optimization of commercial crops of red mombin fruits. The aim of this work was to evaluate the genetic diversity among the provenance of red mombin of two municipalities of the state of Goiás. The fruits were harvested at ripening stage 3 and transp

9. Biometry and genetic diversity of paradise nut genotypes (Lecythidaceae)
Resumo: O objetivo deste trabalho foi avaliar a biometria de frutos e sementes e a diversidade de genótipos de sapucaia (Lecythis pisonis). Frutos de 12 genótipos de sapucaia foram coletados de plantas na região norte do Estado do Espírito Santo e leste do Estado de Minas Gerais. Os dados foram submetidos à análise de variância, e as médias dos difer

10. Multivariate analysis of productive and nutritional traits and feeding behavior of sheep fed roughage-free diets
ABSTRACT The objective of this study was to evaluate productive traits in sheep fed roughage-free diets by multivariate analysis. Forty lambs were used in this study: 20 Santa Inês animals, consisting of 10 uncastrated males and 10 females; and 20 crossbreds (½ Santa Inês × Dorper), consisting of 10 uncastrated males and 10 females, at an average age of

12. Genetic variability of the components of seed yield in interspecific hybrids of Paspalum
ABSTRACT This study aimed to determine the variability and expression of the components of seed yield in twenty-three apomictic Paspalum plicatulum × Paspalum lepton hybrids and two male parent plants (P. lepton). We used a randomized block design with genotypes individually arranged into ten blocks. The variables were: number of total tillers/plant, number
