“…This fact is relevant because the higher the coefficient of kinship between populations, the more difficult it is to discriminate them. For traits controlled by fewer genes, such as disease resistance, plant architecture, and grain appearance (Batista et al, 2017;Moura et al, 2016;Silva et al, 2013), lower variability between populations is expected because they share the same alleles from the common parent. Thus, all the variability between populations is conditioned to the noncommon parent.…”

“…In autogamous plant breeding programs, the selection of inbred progenies that aim at extracting superior lines for quantitative traits are evaluated in different environments (i.e., growth season, sites, and years). In this sense, progenies are evaluated in different inbred generations (Batista et al, 2017;de Resende et al, 2015de Resende et al, , 2016Pereira et al, 2017a). Thus, data from these generations can be used in a multigeneration index (de Resende et al, 2015Resende et al, , 2016, which leads to more accurate genetic value estimates when compared with the traditional methodologies based on the mean between progenies or the last generation evaluated.…”

Core Ideas Partitioning of the progenies effect within populations has several advantages. FAI‐BLUP index capitalizes the progenies × growth seasons interaction. The selected inbreed progenies showed favorable genotypes for the target traits. Genetic breeding towards the common bean ideotype can accelerate the cultivar release. ABSTRACTThe goal of breeding programs is selection toward the ideal plant type. In this study, field experiments were performed to select common bean inbred progenies that maximize the probability of extracting superior lines. A total of 124 inbred progenies of three consecutive generations (F2:3, F2:4, and F2:5) were conducted in field experiments over three different environments (one generation in each environment). Seven different traits, related to disease severity, commercial acceptance grain, and yield, were evaluated by best linear unbiased prediction. This work underscored the importance of incorporating population information into the statistical model as a means of comparing progenies from different populations with higher efficacy, even when kinship information between populations is not available. Toward the common bean ideotype, 20 inbred progenies of greater potential were selected using the factor analysis and genotype‐ideotype distance (FAI‐BLUP) index. This index is based on the structural equation models by joining the factor analysis technique (exploratory factor analysis) with the ideotype design (confirmatory factor analysis). The predicted genetic gain was increased for all the traits in all generations. Selection strategies that capture the multitrait information capitalize the progenies × growth season interactions and are based on the ideotype, such as as the FAI‐BLUP index, have the potential for use in genetic breeding toward the common bean ideotype and can accelerate the release of more adapted cultivars.

“…This test allows determining the predominant segregation pattern that indicates whether it is governed by one, two, or more genes, as well as the predominant type of interaction (Liu 1997). The chi-square test has been proven to be practical and efficient in testing the hypotheses of segregation patterns (Batista et al 2017) for it considers the deviations between expected and observed values and the number evaluated (Schuster and Cruz 2004).…”

Physiological disturbances are one of the major bottlenecks to the expansion of papaya crops due to the negative influence on fruit quality. Studies on genotypes of light-green color have become essential to the development of strategies of tolerance to the physiological disorder skin freckle. Understanding the inheritance of qualitative traits is crucial to selection and prediction of the behavior of segregating generations. Thus, this study aimed to determine the inheritance of the qualitative trait leaf color in segregating generations of crosses between the dark-green cultivar BSA and the light-green cultivar GPC. Inheritance was determined based on the Mendelian genetics laws, by evaluating the phenotypic proportions in the analysis of generations P 1 (BSA), P 2 (GPC), F 1 , F 2 , BC 1 , BC 2 , BC 2r , and F 2:3. The inheritance of light-green leaves from the crossing between BSA and GPG is due to double recessive epistasis.

Fusarium wilt–common bean pathosystem: Pathogen variability and genetic control

et al. 2023

Sustainable management of plant diseases has been a challenge in the effort to feed a human population that has increased substantially. One of the main diseases that affect common bean and dry bean is Fusarium wilt, caused by the fungus Fusarium oxysporum f. sp. phaseoli (Fop), which can cause losses of up to 100% in crop production. The Fop infection process starts in the roots, followed by colonization and obstruction of xylem vessels, leading to leaf wilting, vascular discoloration, chlorosis, dwarfism, and premature plant death. Fop show high genetic variability, and seven different physiological races have been reported in different regions of the world. There is also a study in which the formae specialis designation has been replaced by Fusarium species. Different studies in common bean have shown that physical, biological, and chemical changes are involved in the Fop resistance mechanism and in the Fusarium and common bean pathosystem. Many studies have been conducted to detect candidate genes and pathways associated with resistance to Fop. This work offers useful information for advancing common bean resistance breeding.
