Abstract

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.

不同方法评价蚕豆(Phaseolus vulgaris L.)遗传分化

采用多变量分析方法，对北弗鲁米嫩塞达西里贝罗大学种质资源库的14份蚕豆材料进行了基因型-环境(播季)互作的形态农艺多样性分析。试验采用随机区组设计，设4个重复，于2001年4 ~ 8月(秋冬季)和10 ~ 12月(夏季)两个播种季节进行。与夏季数据相比，聚类分组方法与秋季/冬季数据更符合。不同环境(播种季节)的聚类相似性降低。指出了UENF 1469与UENF 1488之间、UENF 1469与UENF 1486之间的杂交，以及它们与UENF 1488的f1杂交组合，以提供分离代。品种unf 1486, unf 1487, unf 1488, unf 1483，和unf 1579也适用于夏季种植，处于实验水平。

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 The article must be unpublished.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.
