Abstract

Abstract: Knowledge of the genetic variability and of the variables for evaluating common bean lines for the physiological seed quality trait is important for the selection of promising common bean genotypes for this trait in breeding programs. Through multivariate analysis, the objective of this study was to evaluate the efficiency of physical and physiological tests for studies of genetic variability in seeds of common bean lines. Twenty lines of common bean were evaluated for thousand-seed weight, first count, germination, tetrazolium, electrical conductivity, accelerated aging, field emergence and seedling performance. The experimental data were subjected to analysis of variance, analysis of genetic parameters and multivariate analysis of principal components. Genetic variability was observed among the common bean lines, and two groups of lines with superior physiological performance according to the germination and seed vigor tests were identified. First germination count, germination, seedling length in the field, accelerated aging and emergence speed index tests are the most promising for characterizing the physiological potential of seeds of common bean lines.

应用多变量分析方法评价了普通豆种子生理品质性状的遗传变异

摘要:了解普通豆生理种子品质性状的遗传变异和评价变量，对于在育种计划中选择有前途的普通豆基因型具有重要意义。本研究通过多变量分析，评价了物理和生理试验在普通豆系种子遗传变异研究中的有效性。对20个普通豆品系的千粒重、初粒数、发芽率、四氮唑、电导率、加速老化、田间出苗率和出苗性能进行了评价。对实验数据进行方差分析、遗传参数分析和主成分多变量分析。观察了普通豆品系间的遗传变异性，鉴定出发芽和种子活力试验生理性能较好的两组品系。首次萌发数、萌发率、田间苗长、加速老化和出苗速度指数试验是评价普通豆系种子生理潜能最有希望的指标。

期刊介绍： From 2017 the Journal of Seed Science (JSS) will circulate online version only. Original scientific studies and communications, not yet published or submitted to another journal for publication and written in Portuguese or English, will be accepted for publication. For manuscripts submitted in English, the authors should provide an adequated version. The SCIENTIFIC COMMUNICATION is a category of scientific manuscript which describes a technique, an equipment, new species or observations and surveys of limited results. It has the same scientific rigor as the “Scientific Articles” and the same value as a publication. The classification of a manuscript as a SCIENTIFIC COMMUNICATION is based on its content and scientific merit but it can be a preliminary study, simple and not definitive on a certain subject, with publication justified by its uniqueness and contribution to the area. The Editorial Board of the JSS may invite leading authors of recognized reputation to compose specific Review Articles covering topics of their specialization that will convey to the scientific community the state-of-the-art knowledge related to the specific theme.
