Genetic divergence in snap-bean (Phaseolus vulgaris L.) evaluated by different methodologies
Fourteen snap-bean accessions of the Germplasm Bank of the Universidade Estadual do Norte Fluminense Darcy Ribeiro (UENF) were analyzed for their morphoagronomical diversity in genotype-environment (sowing season) interaction, by multivariate analyses. The experiment was conducted in a randomized block design with four replications, in two sowing seasons (April to August - autumn/winter and October to December - summer), in 2001. The clustering grouping methods were in more agreement with autumn/winter data than with the summer data. There was a reduced similarity in the clusters among environments (sowing season). Crossings between UENF 1469 and UENF 1488 and between UENF 1469 and UENF 1486 were indicated, as well as their F 1 hybrid in combination with UENF 1488 for providing segregant generations. Accessions UENF 1486, UENF 1487, UENF 1488, UENF 1483, and UENF 1579 are also indicated for summer planting, in an experimental level.
期刊介绍：
The CBAB – CROP BREEDING AND APPLIED BIOTECHNOLOGY (ISSN 1984-7033) – is the official quarterly journal of the Brazilian Society of Plant Breeding, abbreviated CROP BREED APPL BIOTECHNOL.
It publishes original scientific articles, which contribute to the scientific and technological development of plant breeding and agriculture. Articles should be to do with basic and applied research on improvement of perennial and annual plants, within the fields of genetics, conservation of germplasm, biotechnology, genomics, cytogenetics, experimental statistics, seeds, food quality, biotic and abiotic stress, and correlated areas. The article must be unpublished. Simultaneous submitting to another periodical is ruled out. Authors are held solely responsible for the opinions and ideas expressed, which do not necessarily reflect the view of the Editorial board. However, the Editorial board reserves the right to suggest or ask for any modifications required. The journal adopts the Ithenticate software for identification of plagiarism.
