“…Among the 28 correlations analyzed, 20 presented genotypic magnitudes higher than phenotypic ones, especially when they showed negative values (Table 1). These results are desirable for selection, as the environmental effects have not outweighed the genetic effects (Dvorjak et al., 2019). For other variables, the genotypic correlation showing higher magnitudes than the phenotypic correlation, but there was no significant variation between both correlations in some associations.…”

The knowledge of the associations between the variables and the cause‐effect discrimination allows the breeders to make efficient of new cultivars development with traits that meet of producers and consumers demands. Therefore, the present work aimed to study the associations and among the quality variables of papaya (Carica papaya L.) fruits and the effects in selection process. Eight variables related to fruit quality were evaluated in 62 topcross hybrids. The phenotypic and genotypic correlations and path analyses, were performed to verify the associations between the variables and the effects on pulp volume. Canonical correlation analysis between primary and secondary quality variables was also carried out. Fruit firmness (FF) and soluble solids content showed a positive and significant genotypic correlation, providing evidence for selecting fruits with high averages for both variables. Fruit weight and pulp thickness (PT) were the variables that most contributed to the reduction and increased pulp volume percentage (%PV), respectively. The canonical correlation analysis showed an increase in PT associated with an increase in the fruit length and %PV variables. The physical‐chemical variables showed a low association with others, which will make the selection process more laborious to obtain satisfactory gains between the groups of variables.This article is protected by copyright.

“…Furthermore, the traits of HPI and NDM must be prioritized in the selection of superior soybean genotypes due to their direct and indirect effects on GY, which were very influential in all cultivation environments. Hence, indirect selection to increase GY is an efficient selection strategy to optimize the genetic gain of soybeans [ 40 ], even when considering contrasting environments.…”

Genotype × environment (G×E) interaction is an important source of variation in soybean yield, which can significantly influence selection in breeding programs. This study aimed to select superior soybean genotypes for performance and yield stability, from data from multi-environment trials (METs), through GGE biplot analysis that combines the main effects of the genotype (G) plus the genotype-by-environment (G×E) interaction. As well as, through path analysis, determine the direct and indirect influences of yield components on soybean grain yield, as a genotype selection strategy. Eight soybean genotypes from the breeding program of Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA) were evaluated in field trials using a randomized block experimental design, in an 8 x 8 factorial scheme with four replications in eight different environments of the Cerrado of Northeastern Brazil during two crop seasons. Phenotypic performance data were measured for the number of days to flowering (NDF), height of first pod insertion (HPI), final plant height (FPH), number of days to maturity (NDM), mass of 100 grains (M100) and grain yield (GY). The results revealed that the variance due to genotype, environment, and G×E interaction was highly significant (P < 0.001) for all traits. The ST820RR, BRS 333RR, BRS SambaíbaRR, M9144RR and M9056RR genotypes exhibited the greatest GY stability in the environments studied. However, only the BRS 333RR genotype, followed by the M9144RR, was able to combine good productive performance with high yield stability. The study also revealed that the HPI and the NDM are traits that should be prioritized in the selection of soybean genotypes due to the direct and indirect effects on the GY.

“…Magashi et al, (2018) observed the association among some qualitative characters of different varieties of Soybean in the Sudan Savannah region. Dvorjak et al, (2019) conducted experiment to estimate the phenotypic and genotypic correlations between agronomic characters and perform a path analysis in order to identify growth components for indirect selection of high grain yielding variety of soybean crop. Patil and Deshmukh (1989) and Iqbal et al, (2003) also described the use of path analyses in blackgram breeding.…”
