Tarazi, Roberto; Moreno, Maria Andréia; Gandara, Flávio Bertin; Ferraz, Elza Martins; Moraes, Mário Luiz Teixeira [UNESP]; Vinson, Christina CleoMade available in DSpace on 2022-04-28T21:00:17Z (GMT). No. of bitstreams: 0 Previous issue date: 2010-03-15; Dipteryx alatais a native fruit tree species of the cerrado (Brazilian savanna) that has great economic potential because of its multiple uses. Knowledge of how the genetic variability of this species is organized within and among populations would be useful for genetic conservation and breeding program...
Outcrossing rate of Couratari multiflora (J.Smith) Eyma (Lecythidaceae), a low-...
Lepsch-Cunha, Nadja; Kageyama, Paulo Yoshio; Vencovsky, Roland; Nascimento, Henrique Eduardo MendonçaFoi utilizado um modelo de cruzamento misto multilocos para analisar o sistema de cruzamento de uma população de Couratari multiflora, espécie arbórea emergente encontrada em baixas densidades (1 indivíduo/10 ha) nas florestas de "terra firme" da Amazônia central. Inventariamos e observamos fenologicamente 41 árvores em uma área de 400 ha. Dessas, somente quatro árvores-mãe foram analisadas, pois poucas árvores...

Effective population size and genetic gain expected in a population of Coffea c...
Resende, Marcos Deon Vilela de; Mistro, Júlio César; Fazuoli, Luiz Carlos; Vencovsky, RolandThis work aimed to study the effective population size and genetic gain in a population of robusta coffee (Coffea canephora Pierre) and verify the possibility of using recurrent selection. The experiment comprised 25 treatments, consisting of 21 C. canephora progenies and four C. arabica (cultivars) grown in Brazil. The experimental design was a 5x5 quadruple balanced lattice, with 24 replications, with one pla...

Tambarussi, Evandro Vagner; Ann Veasey, Elizabeth; Menezes, Lou; Ibañes, Bruna; Lombardi, Kátia Cylene; Vencovsky, RolandThe aim of this study was to evaluate the genetic diversity among native plants and some individuals obtained from crosses with unknown genealogy of C. walkeriana as well as C. loddigesii and C. nobilior and to advance towards solving the question of the genetic purity of the “Orchidglade” clone. Eight microsatellite loci were used to evaluate the genetic diversity between individuals of C. walkeriana. Microsat...
