Abstract

ABSTRACT The objective of this work was to perform simultaneous selection in sweet potato genotypes and to verify the efficiency of fuzzy systems when compared to the Mulamba & Mock (MM) method. The experiment was carried out in randomized blocks, with 24 sweet potato genotypes, four replications and ten plants per plot. The breeding values were obtained by the mixed model methodology (REML/BLUP), and then the MM index and the gains obtained by the developed fuzzy systems were estimated. There was a predominance of environmental effects over genotypic effects for all traits. These estimates suggest an expressive contribution of the environment for these traits and, consequently, greater difficulty for genetic improvement. Through this, the fuzzy systems stood out in relation to the MM method, as they presented superior selection gains for characters related to human and animal food. The genotypes with potential for human and animal food selected by the fuzzy system were: UFVJM07, UFVJM05, UFVJM09, UFVJM40, UFVJM01, UFVJM25, UFVJM15. The fuzzy logic was efficient in the simultaneous selection of sweet potato genotypes, allowing the selection of plants similar to the desirable ideotype than the MM method.

模糊逻辑在甘薯基因型同时选择中的应用

摘要本工作的目的是对甘薯基因型进行同时选择，并与Mulamba&Mock（MM）方法相比验证模糊系统的有效性。该试验是在随机区块中进行的，每个区块有24个红薯基因型，4个重复和10个植株。通过混合模型方法（REML/BLUP）获得育种值，然后估计MM指数和所开发的模糊系统获得的增益。所有性状的环境效应均高于基因型效应。这些估计表明，环境对这些性状有明显的贡献，因此，遗传改良的难度更大。通过这一点，模糊系统在MM方法中脱颖而出，因为它们为与人类和动物食物相关的性状提供了优越的选择增益。通过模糊系统筛选出的具有人类和动物食品潜力的基因型为：UFVJM07、UFVJM05、UFVJM09、UFVQM40、UFVJCM01、UFVJF25、UFVJN15。模糊逻辑在红薯基因型的同时选择中是有效的，与MM方法相比，它可以选择与理想理想理想型相似的植物。
