Relação entre a variação genética de caracteres quantitativos e marcadores moleculares em subpopulações de cagaiteira (Eugenia dysenterica DC)

Abstract: O objetivo do trabalho foi relacionar a diversidade genética medida a partir de três diferentes marcadores moleculares, com a variação genética quantitativa de caracteres poligênicos, estimada em ensaio de progênies, sob condições controladas. As progênies, oriundas de dez subpopulações naturais de cagaiteira do sudeste de Goiás, foram avaliadas em experimento em blocos completos casualizados, com quatro repetições e uma planta por parcela. Foram estimadas a herdabilidade ao nível de média de progênies (h mi ²… Show more

“…These accessions were differentiated by the plants with lower height and the highest MMS values as important agronomic characteristics for selection of progenitors. A positive and significant correlation between measures of genetic variation of quantitative characteristics and molecular markers has been verified in other studies and even in different species such as Cagaiteira (Eugenia dysenterica DC., Myrtaceae) (Aguiar et al, 2011;Vieira et al, 2013). In spite of lack of significant correlation among morphologic descriptors and the molecular markers in this study, it is emphasized that the stem hairiness, leaf shape, foliar basis symmetry, leaf incision, angle of the leaf on the main stem, leaf hairiness, extrafloral nectary, color of the flower corolla, capsule hairiness, and color of the seeds were contributive to discrimination of sesame accessions, because they presented more than one class.…”

“…Many different species of the Cerrado have been reported as of favorable genetic variability (Ganga et al, 2009;Carmargo et al, 2010), this information is a good indication to start breeding trials. Due to the lack of information on various aspects of Caryocar brasiliense, progeny tests, mainly used to estimate genetic parameters and select individuals, are an important tool (Aguiar et al, 2011) to calculate the genetic variability of the matrices, respecting the morphological traits of the fruits (Ramos et al, 2015).…”
