Abstract

Abstract: The selection of soybean genotypes with seeds of high physiological quality is key to increasing the likelihood of establishment and success in the field and thus reaping higher yields. The aim of this study was to evaluate the genetic control of the physiological quality of soybean seeds from a partial diallel cross. Six previously selected soybean cultivars, group 1 (CD 201, CA 115, MS 8400) and group 2 (CD 202, Syn 1263, Syn 1279), were intercrossed by a partial diallel cross, totalizing 24 treatments. Seeds from these cultivars and crosses were evaluated for seed physiological quality based on germination tests, first germination count, accelerated aging, seedlings emergence, and emergence speed index. The lignin content in the soybean seed coat was evaluated. The effects on general and specific combining ability and reciprocal effects were analyzed. There were significant additive and non-additive effects of the genes on the seed quality traits and pronounced effects on the reciprocal traits, which suggest the presence of a maternal effect. Lignin content was not correlated with the physiological test results in the studied genotypes.

大豆种子品质的部分双列遗传控制

摘要:选择生理品质优良的大豆基因型是提高大豆在田间建立和成功的可能性，从而获得更高产量的关键。本研究的目的是评价大豆部分双列杂交种子生理品质的遗传控制。采用部分双列杂交方法，对6个已筛选的大豆品种(1组(cd201、CA 115、MS 8400)和2组(cd202、Syn 1263、Syn 1279)进行24个处理的杂交。通过萌发试验、首次萌发次数、加速老化、出苗率和出苗率指数对这些品种和杂交品种的种子进行了生理品质评价。测定了大豆种皮中木质素的含量。分析了对一般配合力和特定配合力的影响以及相互效应。基因对种子品质性状有显著的加性和非加性影响，对互易性状有显著的影响，表明存在母体效应。在研究的基因型中，木质素含量与生理试验结果不相关。

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.
