1. Correlation and selection gains in F6 wheat genotypes
ABSTRACT The agronomic traits have complex quantitative inheritance, wheat breeding has a highly cost and time expending to achieve advanced lines, and new cultivars. The objective of this work was to estimate the phenotypic (rp), genotypic (rg) and environmental (re) correlation coefficients and the genetic parameters, as well as to estimate the selection g

2. Potential of forage and grain yield of maize genotypes in the Brazilian semiarid region
ABSTRACT Maize is importance in the semiarid region due to its forage potential. However, the large number of hybrids on the market hampers the selection of the hybrid by the producer. Given the above, the objective of this paper is to identify genotypes with productive potential for forage and grain production according to the characteristics of the semiari

3. Selection strategies in a segregating passion fruit population aided by classic and molecular techniques
ABSTRACT Combining the use of agronomic, disease-resistance, and molecular informationcan greatly contribute to genetic progress in breeding programs. This study was developed to estimate the genetic distance between genotypes derived from backcrosses and their parents using morphoagronomic and molecular information and information pertaining to resistance t

4. Genotype x environment interaction, adaptability and stability of ‘Piel de Sapo’ melon hybrids through mixed models
Abstract The aim of this study was to evaluate the genotypic performance of twelve Piel de Sapo melon hybrids in the Mossoró-Assú agricultural region, state of Rio Grande do Norte, Brazil, using mixed models. Adaptability and stability of the predicted genotypic values were studied by the Harmonic Mean of the Relative Performance of Genotypic Values (HMRPG

5. Identification of core locations for soybean breeding in Southern Brazil
Resumo: O objetivo deste trabalho foi identificar locais-chave de teste em duas macrorregiões sojícolas no Brasil, para avaliação e seleção de linhagens de soja (Glycine max). Foram testadas 22 cultivares em 23 locais, nessas duas macrorregiões (MR1 e MR2), durante quatro anos, de 2012 a 2015. Os ensaios foram conduzidos em delineamento de blocos ao a

7. Genetic parameters and selection of sugarcane in early selection stages for resistance to sugarcane borer Diatraea saccharalis
Abstract A T1 (sugarcane population originating from true seeds) and T2 (first sugarcane clonal stage) population were used to estimate genetic parameters and compare selection strategies for Diatraea saccharalis (Lepidoptera: Crambidae) resistance in sugarcane. In the T1 stage, heritability at the family mean level (h²=0.77) was higher than individual geno

9. ADAPTABILITY AND PHENOTYPIC STABILITY OF LETTUCE CULTIVARS IN A SEMIARID REGION
RESUMO O estudo de genótipos, em diferentes ambientes ou épocas de cultivo, tem grande importância para a cultura da alface, cuja expressão do potencial produtivo é influenciada pelas condições ambientais. Deste modo, a aplicação da metodologia de modelos mistos (REML/BLUP) tem sido utilizada para avaliar os efeitos da interação genótipo x ambien

10. Genetic parameters and agronomic characterization of elite barley accessions under irrigation in the Cerrado
ABSTRACT. There is a demand for barley cultivars that are suitable for the malt industry as well as genotypes that are stable and better adapted for irrigation in the Cerrado. This study aimed to estimate the genetic parameters by assessing 69 barley genotypes from different countries, from 2012 to 2014, under irrigation in the Cerrado. Six agronomic charact

11. Selection and recommend of quinoa (Chenopodium quinoa) genotypes based on the yield genotypic adaptability and stability
ABSTRACT The present study aimed to select and recommend quinoa genotypes based on the yield genotypic adaptability and stability, by the method of the Harmonic mean of relative performance of genotypic values. Five experiments were conducted during the crop seasons of 2014 and 2015 in two locations in the Western region of Paraná State, Brazil. This study

12. Resistance to Pratylenchus brachyurus in Vitis species population through multivariate approaches and mixed models
ABSTRACT: Genetically diverse interspecific hybrids of Vitis were selected for resistance to Pratylenchus brachyurus. Three segregating populations with 57 hybrid crosses were evaluated. The parents included Vitis romanetiiC166-043 × 07355-075, 06354-047 × Cereza and 06354-047 × Nocera, selected from the germplasm bank at the University of California, Dav
