Special Issue Information

Dear Colleagues,

Fruit is the main source of minerals and vitamins essential for the human body. The fruit tree industry is therefore an important driving force for the development of the agricultural economy. Germplasm resources and important functional genes are the basis of fruit breeding and germplasm innovation. The research and utilization of fruit germplasm resources is of great significance to promote the development of the fruit industry. In recent decades, germplasm resources and genetic improvement have greatly benefited from the knowledge of tree genomics and genetics, as well as the development of modern biotechnologies. This Special Issue, entitled “Research on Germplasm Resources and Genetic Improvement of Tree Fruit”, will highlight recent progress in the research and utilization of fruit germplasm resources.

The main focus of this Special Issue is:

(1) the identification, evaluation, and characterization of tree fruit germplasm;
(2) the identification and breeding utilization of favorable genes which have not been fully explored;
(3) genetic mapping, fine mapping, and genome wide association analysis of loci/genes for important traits of tree fruit;
(4) the development and breeding utilization of molecular markers tightly linked to important traits of tree fruit.

Commercial fruit production in Norway is located at around latitude 60° north, demanding a careful choice of adapted cultivars. The most comprehensive collection of apple genetic resources in Norway is being kept in the Norwegian Apple Collection (NAC) at the Njøs Fruit and Berry Centre (NJØS). The collection contains around 350 accessions and was recently genotyped with a single nucleotide polymorphism (SNP) array. Curated SNP data were used for the assessment of structure and diversity, pedigree confirmation, and core collection development. In the following SNP analysis, we identified several duplicates and parent-child relationships. Across the geographic regions represented, the collection was equally diverse. Different methods for analyzing population structure were applied. K-means clustering and a Bayesian modeling approach with prior assumptions of the data revealed five subpopulations associated with geographic breeding centers. The collection has a distinct genetic structure and low relatedness among the accessions; hence, two core collections with 100 accessions in each were created. These new core collections will allow breeders and researchers to use the NAC efficiently. The results from this study suggest that several of the accessions in the Norwegian Apple Collection could be of high importance for breeding purposes. Full article
