Tissue strength of sugar beet (Beta vulgaris L.) roots could be an interesting breeding target, as it is a possible indicator for storability and influences the manufacturing process. The objective of this study was to analyze the importance of genotype and environment and their interaction on three texture parameters (puncture resistance, tissue firmness, and compressive strength) and to investigate the range of tissue strengths of commercial sugar beet genotypes. For that purpose, two trial series were conducted with six sugar beet genotypes in seven environments across Germany in 2018 and 2019. A screening was performed with 12 commercial genotypes at one site in 2020. Tissue firmness and compressive strength were closely correlated with the puncture resistance of sugar beet roots. The genotype effect was distinctly higher for the texture parameters than for yield and quality parameters, whereas the genotype × environment interaction was negligible, allowing a selection based on few sites. For both genotype and environment, compression strength was closely related to the relative sugar content of the beets. Commercial genotypes also covered a wide range of tissue strengths. These differences might affect harvest damage, storage losses, and subsequent processing steps in the factory.

甜菜根基因型变异的组织强度和环境影响

甜菜组织强度（Beta vulgaris L.) 根可能是一个有趣的育种目标，因为它是一个可能的耐贮性指标并影响制造过程。本研究的目的是分析基因型和环境的重要性及其对三个质地参数（抗穿刺性、组织硬度和抗压强度）的相互作用，并调查商业甜菜基因型的组织强度范围。为此，2018 年和 2019 年在德国的 7 个环境中对 6 个甜菜基因型进行了两个系列试验。 2020 年在一个地点对 12 个商业基因型进行了筛选。组织硬度和抗压强度与抗穿刺性密切相关甜菜根。质地参数的基因型效应明显高于产量和质量参数，而基因型与环境的相互作用可以忽略不计，允许基于少数位点进行选择。对于基因型和环境，抗压强度与甜菜的相对糖含量密切相关。商业基因型还涵盖了广泛的组织强度。这些差异可能会影响收获损坏、储存损失和工厂的后续加工步骤。
