Tridge summary

This article introduces the challenges faced in breeding kiwiberry, a new and difficult fruit crop, due to its complex genetic and environmental factors. The article highlights the need for marker tools to facilitate breeding and focuses on a thesis aimed at exploring the genetic basis of fruit quality traits in kiwiberry. The thesis developed a high-density SNP genotyping array and performed linkage and QTL mapping in a bi-parental kiwiberry population, leading to the development of tools to improve the precision and efficiency in kiwiberry breeding.

Samenvatting (Engelstalig)Kiwiberry is a relatively new fruit crop that is woody, perennial, polyploid, and dioecious with a long juvenile phase about 3-6 years. Many economically important traits are quantitative and are expected to be under the genetic control of numerous genes. Variation in these traits is often influenced significantly by environmental effects and measurement methods. These traits are difficult to improve using conventional breeding methods and are even more challenging for a polyploid crop. There is a need to develop marker tools to facilitate breeding in kiwiberry. However, this area has not been well studied in kiwiberry. This thesis aims to address this knowledge gap by exploring the genetic basis of fruit quality traits in kiwiberry. We developed a ...
