Abstract

Human consumption of vegetable soybeans is increasing, and consequently, breeding programs need to be encouraged and optimized. Therefore, there is a need to understand the relationship between the traits evaluated in the R6 (full seed) and R8 (full maturity) stages and estimate genetic divergence. At two sites and two crop seasons, we evaluated 42 progenies (F6 generation) from crosses between vegetable soybean genotypes and three commercial cultivars. In general, we found significant coincident correlations between environments. Positive and significant correlations between pod width (PWR6) and hundredseed weight (HSW) and between PWR6 and hundred-pod weight (HPW) suggest the possibility of replacing the labor-intensive process of obtaining HSW and HPW by estimating PWR6, which is faster and easier to apply. The unweighted pair-group method arithmetic average analysis allocated soybean genotypes into six major clusters. Furthermore, information from the present work may guide practical actions in breeding programs.

菜用大豆的改良:未成熟植株与成熟植株的遗传多样性及性状相关性

人类对蔬菜大豆的消费量正在增加，因此，需要鼓励和优化育种计划。因此，有必要了解在R6(完整种子)和R8(完全成熟)阶段评价的性状之间的关系，并估计遗传分化。在两个地点和两个作物季节，我们对蔬菜大豆基因型与3个商品品种杂交的42个后代(F6代)进行了评价。总的来说，我们发现环境之间存在显著的一致相关性。荚果宽度(PWR6)与百粒重(HSW)、百粒重(HPW)呈显著正相关关系，说明通过估算PWR6来代替劳动密集型的获取高粒重和百粒重的过程是可行的，而且更快、更容易应用。非加权对组法算术平均分析将大豆基因型划分为6个主要聚类。此外，来自本工作的信息可以指导育种计划的实际行动。

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 The article must be unpublished.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.
