1. Productivity and postharvest durability of Heliconiaceae grown in full sun in the Midwest region of Brazil
ABSTRACT Flower stems of the Heliconiaceae family are gaining more and more space in the Brazilian market of ornamental plants and further knowledge about quality, productivity, and postharvest management is necessary. The objective of the present study was to evaluate heliconiaceae cultivated in full sun in the central-west region of Brazil in terms of agro

2. Agronomic trait selection and pre-germinative treatments in passion fruit hybrid
ABSTRACT Seed biometry and dormancy overcoming methods should be considered in the passion fruit production chain, in the seedling production stage, because of the different characteristics that condition the seedlings. The objective of this work was to identify and correlate the main biometric characteristics between seeds and seedlings and to select the be

3. Inbreeding depression and genetic variability of populations for green maize production
ABSTRACT The production of green maize is considerable important for various regions of Brazil. It is vital that breeding programs of public institutions seek to meet the needs of this market sector, which has a relevant social role, mainly on small properties. The aim of this study was to estimate the inbreeding depression and the genetic components (m + a

4. Genetic parameters estimation in common bean under weed plant competition
ABSTRACT The present study aimed to estimate genetic parameters of 20 common bean genotypes, commercial and regional bean on weed interference. The agronomic characters analyzed were: average stem diameter (ASD); average plant length (APL); number of pods per pot (NPP); number of locules per pod (NLP); number of grains per pod (NGP); percentage of empty locu

5. Selection to high productivity and stink bugs resistance by multivariate data analyses in soybean
ABSTRACT Stink bugs that affect soybeans are responsible for significant losses in seed production, quality and germination potential, in addition to hindering the mechanized harvest. To develop insect resistant materials, the breeder can compile a selection index by factor analysis. Therefore, the objective of this work was to validate the use of factor ana

6. 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

9. Identification of populations and hybrid combinations of maize for in natura consumption
ABSTRACT Brazil is one of the leading countries in the production of maize (Zea mays), with great potential for growing green maize, which has a superior commercial value in relation to maize marketed in the form of grains. Although important, the availability of cultivars recommended for the production of green maizeis still very scarce. The objectives of t

10. AGRONOMIC POTENTIAL AND GENETIC DIVERSITY OF LANDRACES OF COWPEA OF THE STATE OF CEARÁ
RESUMO Variedades tradicionais são fontes de variabilidade genética, principalmente no que se refere a alelos que conferem tolerância a fatores bióticos e abióticos e, portanto, podem auxiliar os programas de melhoramento no desenvolvimento de cultivares promissoras. Contudo, torna-se necessário conhecer esse patrimônio genético em nível que permita
