Advances in genomics for diversity studies and trait improvement in temperate fruit and nut crops under changing climatic scenarios.

Genetic improvement of temperate fruit and nut crops through conventional breeding methods is not sufficient alone due to its extreme time-consuming, cost-intensive, and hard-to-handle approach. Again, few other constraints that are associated with these species, ., their long juvenile period, high heterozygosity, sterility, presence of sexual incompatibility, polyploidy, etc.
