Abstract

The macadamia (Macadamia integrifolia) is a nut crop tree widespread across eastern Australia.Although, it was introduced in Brazil in 1931, just in the past 20 years its cultivated area hasexpanded more signicantly. However, 80% of the orchards consists of exotic varieties, and just 17local cultivars are available to farmers. Therefore, the lack of local varieties makes indispensable the development of new varieties adapted to local conditions. The macadamia tree is a perennial species that takes a long time to reproduce. Thus, traditional breeding programms takes a long time to deliver new varieties. Molecular techniques could provide genetic information useful for breeding programms, such as, the kinship (relatedness) between ndividuals, detection of quantitative trait loci (QTL) and marker assisted selection. The objective of this study is to develop both microsatellites(SSR) and diversity array technology (DArT) primers that will be used to gain insigths intothe genetic architecture of macadamia that ultimately will be applied to our breeding programm.
