Although genome-wide association studies (GWAS) based on single-marker analysis have been widely applied in plant breeding programs, the effectivity of the methodology is still undermined by high false-positive rates and the limited power to detect associations. Bayesian methods estimated marker effects simultaneously proved to be efficient, indicating genes with important effects. Regional heritability mapping (RHM) on the other hand determines the genome region (group of markers) associated with the phenotype, consider population structure and familial relatedness and is more powerful to detect quantitative trait loci (QTL) and reduced false-positive rates than single marker methodologies. A single-marker mixed model (SM-MM), bayesian approach and RHM were used for 11 traits in 413 rice accessions genotyped for 44,100 SNP markers. Using RHM in regions of 0.21Mb and 0.69 Mb, respectively, detected 5 and 7 associated regions with 163 and 569 single nucleotide polymorphisms (SNPs), bayesian method with regions of 0.21Mb and 0.69 Mb detected regions for all traits, whereas SM-MM detected 4 single SNP?trait associations. For the 11 traits, RHM explained around 25-40 and 25-76% using genome regions of 0.21 and 0.69Mb, respectively, and SM-MM using single markers explained 1?7% of the genomic heritability. Regional heritability mapping was more effective than SM-MM in capturing major proportions of genomic heritability. The regions found in this study were within or close to the QTL noted in the Q-TARO and Gramene QTL databases.

ABSTRACT - The objective of this work was to identify the effect of potassium rates on Bt transgenic resistance and damage caused by Spodoptera frugiperda in corn plants at different developmental stages. The experimental design was a randomized complete block in a 3x6 factorial arrangement, with three potassium rates (0, 45, and 90 kg ha-¹) and six corn hybrids (20A55Hx, 30A77PW, AG1051, MG652PW, NS90VTPro2, and NS92VTPro), with three replicates. The hybrids were evaluated through the analysis of canonical variables. With low potassium rates, the effectiveness of the corn hybrids in controlling the S. frugiperda caterpillar decreases in the different phenological stages. The use of the Bt technology is more efficient under an adequate potassium rate of 90 kg ha-¹ KCl. RESUMO - O objetivo deste trabalho foi identificar o efeito de doses de potássio sobre a resistência transgênica Bt e os danos causados por Spodoptera frugiperda em plantas de milho, em diferentes estádios de desenvolvimento. O delineamento experimental foi de blocos ao acaso, em arranjo fatorial 3x6, com três doses de potássio (0, 45 e 90 kg ha-¹) e seis híbridos de milho (20A55Hx, 30A77PW, AG1051, MG652PW, NS90VTPro2 e NS92VTPro), com três repetições. Os híbridos foram avaliados por meio de análise de variáveis canônicas. Com doses baixas de potássio, a eficácia dos híbridos de milho no controle da lagarta S. frugiperda diminui nos diferentes estádios fenológicos. O uso da tecnologia Bt é mais eficiente quando sob dosagem adequada de potássio de 90 kg ha-¹ KCl.
