Abstract

The stink bug complex is characterized as an important soybean pest that demands the development of cultivars resistant to the attack of these insects to reduce losses in soybean quality and productivity and, therefore, develop a more sustainable agriculture. This study aimed at selecting soybean genotypes with good agronomic traits, including resistance to stink bug complex and identify the key traits that assist in this selection. 256 genotypes obtained by crossing IAC-100 (resistant) × CD-215 (susceptible) were evaluated under natural field infestation, in the 2014/15 harvest using the16x16alpha-lattice design. The multivariate statistical analysis of principal components and non-hierarchical K-means clustering method tested 11 agronomic traits of interest. The genotypes selected for resistance to stink bugs complex were IAC 100, 2, 18, 22, 25, 38, 48, 69, 71, 73, 110, 121, 132, 133, 149, 150, 171, 178, 181, 202, 214, 217, 219, 241 and 242. The studied traits as yield, good seed weight, leaf retention, and 100 seed weight can be used to select resistant genotypes.

大豆抗臭虫复合体基因型鉴定及关键农艺性状选择。

臭虫是一种重要的大豆害虫，需要开发抗臭虫的品种，以减少大豆质量和生产力的损失，从而发展更可持续的农业。本研究旨在筛选具有良好农艺性状的大豆基因型，包括抗臭虫复合物，并确定有助于这一选择的关键性状。采用16x16 α -晶格设计，对2014/15年收获的IAC-100（抗性）× CD-215（敏感）杂交获得的256个基因型进行田间自然侵染评价。主成分多变量统计分析和非分层k均值聚类方法检验了11个感兴趣的农艺性状。抗性基因型为IAC 100、2、18、22、25、38、48、69、71、73、110、121、132、133、149、150、171、178、181、202、214、217、219、241和242。研究的产量、良种重、留叶率和百粒重等性状可用于抗性基因型的选择。
