“…Results from an agroclimatic zoning model indicate that north and northeast Argentina are also suitable (Falasca et al 2017). Similar predictions are available for Brazil suggesting the importance of the entire natural occurrence area of A. aculeata for exploring its productive potential (Resende et al 2020). Plath et al (2016) found that 2.8% of the potential area (3.7 M km 2 under present climate conditions) is considered highly suitable by the modeling study and 37.1% moderately suitable.…”

Acrocomia spp., a genus of wild-growing palms in the neotropics, is rapidly gaining interest as a promising multipurpose crop. Diverse products can be derived from various components of the palm, the oils being of highest interest. Acrocomia shows similar oil yield and fatty acid composition to the African oil palm (Elaeis guineensis). It is, however, able to cope with a wider range of environmental conditions, including temporary water scarcity and lower temperatures, thus potentially a more sustainable alternative to its tropical counterpart. Acrocomia’s research history is recent compared to other traditional crops and thus knowledge gaps, uncertainty, and challenges need to be addressed. This review attempts to assess the acrocomia’s preparedness for cultivation by highlighting the state-of-the-art in research and identifying research gaps. Based on a systematic literature search following a value web approach, it (a) provides a comprehensive overview of research topics, (b) shows the development of publication activities over time and the drivers of this development, and (c) compiles main findings to assess the acrocomia’s preparedness for commercial cultivation. Our results confirm its multipurpose characteristic as a potential feedstock for manifold sectors. Research has continued to increase over the last decade, especially on A. aculeata and is driven by the interest in bioenergy. Increasing knowledge on botany has contributed to understanding the genetic diversity and genus-specific biology. This has enabled applied research on seed germination and propagation toward domestication and initial plantation activities, mostly in Brazil. Main research gaps are associated with genotype–environment interaction, planting material, crop management, and sustainable cropping systems. Overall, we conclude that acrocomia is at an early phase of development as an alternative and multipurpose crop and its up-scaling requires the integration of sustainability strategies tailored to location-based social-ecological conditions.

“…We estimated variance components and related genetic parameters for the following quantitative traits: plant height (HEI), trunk circumference 10 cm above ground level (CIR), fruit volume (FRV), and estimated fruit yield (FRY). To calculate the fruit volume (FRV), we used the equation adopted by Resende et al (2020) and Yunes et al (2015), which considers the radial and longitudinal circumferences of fruits. The estimated fruit yield (FRY) was obtained from the product of the fruit mass and number of fruits per plant (developed or immature fruits present on the tree in September 2021, a period marked by the appearance of "falling fruits").…”

Hancornia speciosa is a fruit tree species with potential for exploitation, which makes the adoption of strategies related to its conservation and breeding relevant. Our study aimed to investigate the reproductive phenology, estimate genetic variability, and identify superior H. speciosa genotypes among the accessions that compose the germplasm collection of the Federal University of Goiás, Brazil. Experimental data were obtained from 143 individual accessions. Evaluation of reproductive phenology was conducted on an arbitrary scale of points assigned to trees monthly. Morphological characterization was based on a list of 20 qualitative descriptors and 12 quantitative traits. The dissimilarity between and within botanical varieties and their correlation with the geographic distance of the origin populations were investigated. Analysis of variance components was performed using the Restricted Maximum Likelihood/Best Linear Unbiased Prediction procedure using two linear models. The selection of the ≈ 10% best individual accessions was performed considering genetic and genotypic values. With the exception of H. speciosa var. speciosa, the botanical varieties that compose the germplasm collection showed similar reproductive patterns, with a peak in fruit appearance in August. Morphological dissimilarity was smaller within botanical varieties. Among the botanical varieties, dissimilarity was generally positively correlated with the geographic distance. The adoption of a multivariate selection index procedure enables the prediction of genetic gains, resulting in the selection of genotypes from different similarity groups. Clone selection is the most promising strategy for the improvement of H. speciosa, ensuring a better response to selection in the short term than recurrent selection.

“…Environmental covariates can also be modeled using crop growth models (CG GBLUP) and deep kernel approaches [67,[80][81][82]. Recently, environmental covariates using geographic information system information have been used to better deal with GE [83]. Further, Costa-Neto et al [63] developed an R package called "EnvRtype" to integrate large-scale envirotyping (enviromics) into quantitative genomics for implementation in GS.…”

Plant geneticists and breeders have used marker technology since the 1980s in quantitative trait locus (QTL) identification. Marker-assisted selection is effective for large-effect QTL but has been challenging to use with quantitative traits controlled by multiple minor effect alleles. Therefore, genomic selection (GS) was proposed to estimate all markers simultaneously, thereby capturing all their effects. However, breeding programs are still struggling to identify the best strategy to implement it into their programs. Traditional breeding programs need to be optimized to implement GS effectively. This review explores the optimization of breeding programs for variety release based on aspects of the breeder’s equation. Optimizations include reorganizing field designs, training populations, increasing the number of lines evaluated, and leveraging the large amount of genomic and phenotypic data collected across different growing seasons and environments to increase heritability estimates, selection intensity, and selection accuracy. Breeding programs can leverage their phenotypic and genotypic data to maximize genetic gain and selection accuracy through GS methods utilizing multi-trait and, multi-environment models, high-throughput phenotyping, and deep learning approaches. Overall, this review describes various methods that plant breeders can utilize to increase genetic gains and effectively implement GS in breeding .
