Breeding programmes count on stable trained panels that support breeding evaluation selections. This work aimed to evaluate the performance of a small expert panel in the join IRTA-PFR breeding programme to validate its use in the sensory assessments of fruit pear genotypes during the selection process. A breeding F1 population of 80 pear seedlings from this programme was used. Descriptors and standard references used for sensory evaluations of pear attributes were previously defined by the four members of the expert panel. A General Procrustes Analysis (GPA) was applied to analyse the relations between instrumental and sensory traits. The results showed a good relationship between sensory attributes such as firmness and crispness with penetrometer measures. A high correlation was also found between sensory sourness and titratable acidity (TA). Panel performance was evaluated in terms of reproducibility, homogeneity, and panel consonance. The results indicated that the experts were very consistent and had a good performance. The work demonstrates, for the first time, that a small expert trained panel could be efficiently used in pear breeding programmes and allows for the selection process in a more economical and available way in contrast to the larger sensory panels conventionally used.
育种计划依赖于稳定的训练有素的小组来支持育种评估选择。这项工作旨在评估参与IRTA-PFR联合育种计划的一个小型专家小组的表现，以验证其在选择过程中对梨基因型果实进行感官评估时的用途。使用了该计划中的一个由80株梨幼苗组成的育种F1群体。专家小组的四名成员先前已定义了用于梨属性感官评估的描述符和标准参考。应用广义普罗克汝斯分析（GPA）来分析仪器测量和感官特征之间的关系。结果表明，诸如硬度和脆度等感官属性与 penetrometer 测量值之间存在良好的关系。在感官酸度和可滴定酸度（TA）之间也发现了高度相关性。从可重复性、同质性和小组一致性方面对小组表现进行了评估。结果表明，专家们非常一致且表现良好。这项工作首次证明，一个小型的专家训练小组可以有效地用于梨育种计划，并且与传统使用的较大型感官小组相比，能够以更经济和可行的方式进行选择过程。
