Divergência genética entre genótipos de quinoa quanto a crescimento morfológico e caracteres da panícula Sci. Agrar.Paran. / SAP
de Oliveira, Giovani Andreazza; de Vasconcelos, Edmar Soares; Achre, Diandra.
This study aimed to identify and select genotypes of quinoa (Chenopodium quinoa) with greater genetic distance between them, to compose groups of crossing. For both genotypes were evaluated two distinct populations of Chenopodium quinoa (Cherry Vanilla and Brilliant Rainbow), 15 quantitative characteristics being evaluated to determine the genetic distance and formation of groups with similar plants. The grouping was done by the method of neighbor furthest from the standardized mean euclidean distances, which allowed the division of 44 genotypes into three distinct groups. The crossing were those recommended involving genetic distance greater genotypes, genotype example 22 (group 1, Brilliant population belonging to Rainbow) genotype 34 (third group,...

Queen bee Apis mellifera and the colony productivity Sci. Agrar.Paran. / SAP
Camargo, Simone Cristina; Lima, Erica Gomes de; Toledo, Vagner de Alencar Arnaut de; Garcia, Regina Conceição.
Genetic improvement in beekeeping is mainly focused on increasing the productivity of various bee products, however, when thinking in terms of breeding, it is necessary to produce queen bees and to applicate selection in bee colonies. Even with the development of methods and technologies, there are few practical applications in the apiary. Thus, the aim of this study is to synthesize and disseminate the knowledge about the biology and behavior of queen bees, with further focus on the production of queens, as well as the instrumental insemination and selection, as tools for breeding programs. With the release of this knowledge it is expected that their application would improve the quality and quantity of bee products, keeping the colony with a selected...
