Identification of RAPD markers linked to pod length in Brassica napus L. canola

Abstract

The purpose of this study was to develop molecular markers as a tool to make important agronomic selections in the absence of a scorable phenotype. This project focused on the trait of pod length in Brassica napus L. canola. Pod length is an important parameter involved in total yield in this crop. In this study, the inheritance of long pods was found to be controlled by two independent genes in a dominant relationship with additive effects. Using bulk segregant analysis (BSA) and linkage analysis using RAPD markers, two corresponding linkage groups that segregate with the long pod trait were identified. The application of this trait for possible benefit in a canola breeding program is discussed. Key words: Spring canola, RAPD, pod length, plant breeding, Brassica napus
