1. Effect of stem height in variation of bark, heartwood, sapwood and physical properties of wood in Dipteryx panamensis Pittier in a provenance/progeny test
RESUMO A madeira de Dipteryx panamensis é usada no reflorestamento na Costa Rica, tendo um programa de melhoramento genético iniciado recentemente no país. O objetivo do presente estudo foi estudar o efeito da altura do tronco das árvores na variação de casca, alburno, cerne, densidade verde (GD), densidade básica (SG) e teor de umidade na condição

2. Resistance to witches’ broom in adult plants and progeny of local varieties of cacao in Southern Bahia
ABSTRACT Plants of local cacao variety from Southern Bahia were evaluated in order to verify if there are different levels of resistance to witches’ broom disease in the study population and if the evaluation of adult plants in the field is a good predictor of these resistance levels. The seedlings were maintained under greenhouse conditions and inoculated

3. 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

7. Effect of breeder age and storage conditions of Japanese quail eggs on hatchability, quail neonate quality, and Bursa of Fabricius characteristics
ABSTRACT Two experiments were conducted to evaluate combinations of different storage periods and temperature of hatching eggs of breeder quails in two stages of the production cycle (24 and 43 weeks) on hatchability, quail neonate quality, and Bursa of Fabricius characteristics. In each experiment, a total of 1.050 Japanese quail eggs were incubated in a ra

8. Increasing the resistance of common bean to white mold through recurrent selection
ABSTRACT White mold, caused by Sclerotinea sclerotiorum (Lib.) de Bary is one of the most important diseases of the common bean (Phaseolus vulgaris L.) worldwide. Physiological resistance and traits related to disease avoidance such as architecture contribute to field resistance. The aim of this study was to verify the efficiency of recurrent selection in ph
