摘要

甘薯品种选育是一个漫长的过程。在这个过程中,杂交后代的筛选主要由经验判断决定。数据分析和决策疲劳一直困扰着饲养者。近年来,低效筛选模式已不能满足甘薯种质创新的要求。因此,有必要构建一种高效的方法来筛选不同用途的种质,挖掘优良基因型,并创造专门的甘薯品种。本文基于鲜根产量、藤长、藤径、分枝数、根数和贮藏根空间分布等6个农艺性状,以及干物质含量、商品根产量、根均匀性、淀粉含量和食用质量分数等5个品质性状,构建了多准则决策模型。其中,采用模糊综合评判法,综合颜色、气味、甜味、粘性和纤维味的感官得分,计算出食用质量得分。通过对25种甘薯材料的评价,将MCDM模型与传统筛选方法进行了比较。主观因素对评价结果的干扰显著减少。在甘薯优良材料的筛选中,MCDM模型比传统的筛选方法更全面、更准确、更快。它可以与传统的筛选方法相结合,为育种家服务。

Development of a multicriteria decision-making model for evaluating hybrid offspring in the sweetpotato (Ipomoea batatas L.) breeding process.

Sweetpotato variety breeding is always a long process. Screening of hybrid offspring is dominated by empirical judgment in this process. Data analysis and decision fatigue have been troubling breeders. In recent years, the low-efficiency screening mode has been unable to meet the requirements of sweetpotato germplasm innovation. Therefore, it is necessary to construct a high-efficiency method that can screen germplasms for different usages, for mining elite genotypes, and to create dedicated sweetpotato varieties. In this article, the multicriteria decision-making (MCDM) model was constructed based on six agronomic traits, including fresh root yield, vine length, vine diameter, branch number, root number and the spatial distribution of storage roots, and five quality traits, including dry matter content, marketable root yield, uniformity of roots, starch content and the edible quality score. Among these, the edible quality score was calculated by using fuzzy comprehensive evaluation to integrate the sensory scores of color, odor, sweetness, stickiness and fibrous taste. The MCDM model was compared with the traditional screening method via an evaluation in 25 sweetpotato materials. The interference of subjective factors on the evaluation results was significantly reduced. The MCDM model is more overall, more accurate and faster than the traditional screening method in the selection of elite sweetpotato materials. It could be programmed to serve the breeders in combination with the traditional screening method.
