Abstract

Abstract: Productive soybean genotypes is one of the main objectives of soybean breeding programs. However, there are few studies on the selection of characteristics associated with the quality and performance of soybean seeds. The objective in this study was to predict physiological and genetic parameters associated with seed quality in segregating soybean populations derived from parents of differing maturity groups. Eight genotypes of the F2:3 segregating soybean population (numbered 163, 24, 57, 108, 164, 169, 157, and 81) cultivated in the 2018/19 harvest were evaluated. To conduct the experiment, a completely randomized design was used. The physiological quality of the seeds was evaluated by germination test, tetrazolium test, and image analysis. Statistical analyses were performed by using a mixed model approach. Greater seed vigor was observed in the genotypes 108, 164, and 169, whose results were among the best for most of the analyzed parameters. The greater mechanical damage and damage due to stink bugs can explain the lower vigor of some seeds, as observed in genotypes 57 and 163, while weathering damage did not correspond to the results of the seed vigor tests. The analyses indicated a greater influence of genetic characteristics than of relative maturity group on the responses of the genotypes. No effect of relative maturity group on soybean seed vigor was evident.

大豆种子生理品质及成熟期的影响

摘要大豆高产基因型是大豆育种计划的主要目标之一。然而，对大豆种子品质性能相关性状的选择研究较少。本研究的目的是预测来自不同成熟度群体亲本的大豆群体中与种子质量相关的生理和遗传参数。对2018/19年度栽培的F2:3大豆分离群体(163、24、57、108、164、169、157和81)的8个基因型进行了评价。实验采用完全随机设计。通过萌发试验、四氮唑试验和图像分析对种子的生理品质进行评价。采用混合模型方法进行统计分析。108、164和169基因型的种子活力较强，其结果在大多数分析参数中均为最佳。在57和163基因型中观察到，较大的机械损伤和臭虫损伤可以解释某些种子活力较低的原因，而风化损伤与种子活力试验的结果不一致。分析表明，遗传性状对基因型反应的影响大于相对成熟组。相对成熟组对大豆种子活力无明显影响。

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.
