QTL Mapping for Resistance to Cankers Induced by pv. (Psa) in a Tetraploid Kiwifruit Population.

Polyploidy is a key driver of significant evolutionary changes in plant species. The genus (kiwifruit) exhibits multiple ploidy levels, which contribute to novel fruit traits, high yields and resistance to the canker-causing dieback disease incited by pv. (Psa) biovar 3.

Multiple quantitative trait loci contribute to resistance to bacterial canker incited by pv. in kiwifruit ().

pv. (Psa) biovar 3, a virulent, canker-inducing pathogen is an economic threat to the kiwifruit ( spp.) industry worldwide.

Genetic analysis of resistance to Pseudomonas syringae pv. actinidiae (Psa) in a kiwifruit progeny test: an application of generalised linear mixed models (GLMMs).

Linear Mixed models (LMMs) that incorporate genetic and spatial covariance structures have been used for many years to estimate genetic parameters and to predict breeding values in animal and plant breeding. Although the theoretical aspects for extending LMM to generalised linear mixed models (GLMMs) have been around for some time, suitable software has been developed only within the last decade or so. The GLIMMIX procedure in SAS® is becoming popular for fitting GLMMs in various disciplines.
