Abstract The genus Vaccinium L. (Ericaceae) contains a wide diversity of culturally and economically important berry crop species. Consumer demand scientific research in blueberry (Vaccinium spp.) cranberry macrocarpon) have increased worldwide over the crops’ relatively short domestication history (~100 years). Other species, including bilberry myrtillus), lingonberry vitis-idaea), ohelo reticulatum) are largely still harvested from wild but with improvement efforts underway. Here, we present review article on these crops topics that span taxonomy to genetics genomics breeding. We highlight accomplishments made thus far for each crops, along their journey wild, propose areas questions will require investments by community coming decades guide future efforts. New tools resources needed underpin development superior cultivars not only more resilient various environmental stresses higher yielding, also produce fruit continue meet variety consumer preferences, quality health related traits.

Inheritance of Yield Components and Morphological Traits in Avocado cv. Hass From “Criollo” “Elite Trees” via Half-Sib Seedling Rootstocks

Frontiers in Plant Science, Journal Year: 2022, Volume and Issue: 13

Published: May 24, 2022

Grafting induces precocity and maintains clonal integrity in fruit tree crops. However, the complex rootstock × scion interaction often precludes understanding how phenotype is shaped, limiting potential to select optimum rootstocks. Therefore, it necessary assess (1) seedling progenies inherit trait variation from elite 'plus trees', (2) whether such family superiority may be transferred after grafting scion. To bridge this gap, we quantified additive genetic parameters (i.e., narrow sense heritability-h2, genetic-estimated breeding values-GEBVs) across landraces, "criollo", "plus trees" of super-food crop avocado (Persea americana Mill.), their open-pollinated (OP) half-sib families. Specifically, used a genomic best linear unbiased prediction (G-BLUP) model merge phenotypic characterization 17 morpho-agronomic traits with screening 13 highly polymorphic SSR markers diverse panel 104 "criollo" trees."

In Vitro Polyploid Induction of Highbush Blueberry through De Novo Shoot Organogenesis

Plants, Journal Year: 2022, Volume and Issue: 11(18), P. 2349 - 2349

Published: Sept. 8, 2022

Polyploid induction is of utmost importance in horticultural plants for the development new varieties with desirable morphological and physiological traits. Polyploidy may occur naturally due to formation unreduced gametes or can be artificially induced by doubling number chromosomes somatic cells. In this experiment, a protocol vitro polyploid highbush blueberry (Vaccinium corymbosum L.) leaf tissues was studied using different concentrations colchicine oryzalin. Oryzalin found highly toxic species, while adventitious shoot organogenesis media enriched 25 250 µM able induce polyploidization, significant differences among treatments used. Higher both antimitotic agents led browning death tissues. The polyploids obtained showed several when compared diploid shoots. Flow cytometry analysis used confirm ploidy level regenerated shoots, demonstrating that total 15 tetraploids 34 mixoploids were obtained. stomatal sizes (length width) larger than those diploids, but reduced density observed as controls. These shoots will acclimatized grown until they reach reproductive phase order test their potential appeal use breeding genetic improvement.

A joint learning approach for genomic prediction in polyploid grasses

Scientific Reports, Journal Year: 2022, Volume and Issue: 12(1)

Published: July 21, 2022

Abstract Poaceae, among the most abundant plant families, includes many economically important polyploid species, such as forage grasses and sugarcane ( Saccharum spp.). These species have elevated genomic complexities limited genetic resources, hindering application of marker-assisted selection strategies. Currently, promising approach for increasing gains in breeding is selection. However, due to polyploidy nature these more accurate models incorporating into schemes are needed. This study aims develop a machine learning method by using joint predict complex traits from genotypic data. Biparental populations two Urochloa decumbens , Megathyrsus maximus ) were genotyped, several quantitative measured. High-quality markers used different cross-validation scenarios. By combining classification regression strategies, we developed predictive system with results. Compared traditional prediction methods, proposed strategy achieved accuracy improvements exceeding 50%. Our results suggest that methodology could be implemented programs, helping reduce cycles increase gains.

Abstract Background Triploid oysters, bred by crossing tetraploid and diploid are common worldwide in commercial oyster aquaculture make up much of the hatchery-produced Crassostrea virginica farmed mid-Atlantic southeast United States. Breeding animals for genetic improvement triploid progeny is unique to oysters can proceed via several possible breeding strategies. along with their or relatives, have yet been subject quantitative analyses that could inform a strategy improvement. The importance involving C. has emphasized occurrence mortality events near-market sized triploids late spring. Methods Genetic parameters survival weight were estimated from twenty paternal half-sib families thirty-nine full-sib reared at three sites Chesapeake Bay (USA). Traits analyzed using linear mixed models ASReml-R. relationship matrices appropriate pedigrees produced polyAinv package R. Results A event occurred one site located on bayside Eastern Shore Virginia. Between early May July, had less than 0.70, while most greater 0.90. heritability during this period affected was 0.57 ± 0.23. adversely related low salinity (− 0.50 0.23) unrelated similar (0.05 0.39). Conclusions Survival spring substantial additive basis, suggesting selective tetraploids reduce mortalities. correlations revealed evidence genotype environment interactions weak between triploids. phenotyping half-sibs recommended oysters.
