Genetic Linkage Maps:
Strategies, Resources and
Achievements

ABSTRACT
Sunflower genome mapping has come a long way. This chapter starts
with a brief history of mapping efforts of using morphological and
biochemical markers, and then describes all DNA-based marker
techniques used in sunflower genome mapping. It also reviews the
mapping populations developed and the mapping software packages
available and summarizes the sunflower genome mapping
achievement of approximately 20 published linkage maps. The chapter
ends with listing the challenges to the sunflower research community
in three areas: 1. handling the enormous amount of data of high-
throughput sequence-based markers in sunflower genome mapping
in the near future; 2. correlating DNA sequence alterations with the
quantitative variation of economically important traits; and 3. applying
the mapping achievement to sunflower improvement, the ultimate
goal of genome mapping.
