Single-step genome-wide association study for susceptibility to and precocity of vegetative phase change in .

Introduction: leaf disease (MLD) is one of the most prevalent foliar diseases of plantations around the world. Since resistance management strategies have not been effective in commercial plantations, breeding to develop more resistant genotypes is the most promising strategy. Available genomic information can be used to detect genomic regions associated with resistance to MLD, which could significantly speed up the process of genetic improvement.

Construction of a High-Density Genetic Map of (Berg.) Burret, an Outcrossing Species, Based on Two Connected Mapping Populations.

, known as feijoa or pineapple guava, is a diploid, (2 = 2 = 22) outcrossing fruit tree species native to Uruguay and Brazil. The species stands out for its highly aromatic fruits, with nutraceutical and therapeutic value. Despite its promising agronomical value, genetic studies on this species are limited.
