<b>Genetic variability and progeny selection of peach palm via mixed models (REML / BLUP)

Abstract: ABSTRACT. Heart of palm harvesting and exploitation has reduced the natural reserves of açaí and juçara; hence, the peach palm is an excellent option as source of heart of palm that can reduce the pressure on these two species. The peach palm has high tillering and no post-harvest oxidation. An experiment in a randomized block design with 72 progenies of peach palm, 36 replications and a single tree plot was performed for five years at the experimental field of Embrapa in the Western Amazon. Genetic parameters… Show more

“…A Pupunheira é uma palmeira nativa da América Latina Tropical (Graefe, Dufour, Zonneveld, Rodriguez & Gonzalez, 2013). O seu interesse como produtora de palmito (pupunha) surgiu após a redução de reservas naturais da juçara (Euterpe edulis Martius) e do açaí (Euterpe oleraceae Martius), por meio do extrativismo (Rodrigues et al, 2017).…”

“…Nessa perspectiva, o uso da pupunha tem se apresentado como uma importante alternativa para o cultivo sustentável, pois além de colaborar para a redução da exploração predatória da juçara e açaí, possui crescimento célere e formação de perfilhos (Penteado, Santos & Neves, 2010;Rodrigues et al 2017).…”

“…By contrast, for the fruit weight variable an increase of 0.60 in genetic determination was observed only after the tenth evaluation, suggesting that selection aimed at this variable requires several observations. Rodrigues et al (2017) evaluated the population of heart palm for five years and found low repeatability, and recommended seven measurements for yield. Sanchéz et al 2017found that eight crop season for Annona muricata are necessary for an effective selection.…”

“…Much research has been undertaken to prove the importance of the effect of years on perennial crops, e.g., heart palm (Rodrigues et al, 2017) and citrus (Imai et al, 2016). According to these studies, to select promising genotypes with greater efficiency, it is more advantageous to increase the number of years and locations assessed than the number of progenies.…”

“…Mixed-model methods, such as restricted maximum likelihood and best linear unbiased prediction (REML/BLUP), are efficient in estimating variance components and predicting genetic effects from morphological data, providing accurate results (Resende 2002). Studies on important native tree species, including some palm species such as E. edulis (Guilhen et al 2019), E. oleracea (Navegantes et al 2018), E. precatoria (Ramos et al 2019) and Bactris gasipaes (Rodrigues et al 2017), are hampered by the difficulties of collecting the plant material, illegal tree cutting and data imbalance. To overcome these problems and gain information about the true genetic values, the simultaneous application of REML and BLUP is recommended (Resende 2002).…”
