Abstract

Bean breeders evaluate the water uptake (WU) capacity of lines with the aim of identifying those with the shortest cooking time. There is no information on the most likely effect of the selection for WU in the expression of traits related to germination. To obtain information in this respect, F 2:4 families of crosses between the lines CI-107 with Carioca 80 and Amarelinho were evaluated in relation to WU, germination speed index (GSI), and emergence speed index (ESI). The genetic variance was greatest in cross CI-107 x Amarelinho. The estimate of heritability for ESI was similar in both crosses and inferior to the one obtained for WU. The correlated responses in ESI to the selection practiced in WU were particularly expressive in seeds stored for 6 months. Accordingly, a selection aiming at the identification of lines with shorter cooking t ime

与普通豆种子生理品质有关的遗传参数

豆类育种者评价品系的吸水能力，目的是找出蒸煮时间最短的品系。目前还没有关于选择WU对发芽相关性状表达最有可能影响的信息。为了获得这方面的信息，对CI-107与Carioca 80和Amarelinho杂交的f2:4系进行了WU、萌发速度指数(GSI)和出苗速度指数(ESI)的评价。遗传变异在CI-107 × Amarelinho杂交中最大。两个杂交中ESI的遗传力估计相似，但低于WU的遗传力估计。ESI对WU选择的相关响应在储存6个月的种子中表现得尤为明显。因此，选择的目的是识别烹调时间较短的品系

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 The article must be unpublished.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.
