Presentation Title
Genetic Diversity in Helianthus annuus: Selective Breeding and Induced Mutagenesis
Document Type
Poster Session
Faculty Mentor

Keywords
genetics, sunflower, mutagenesis
Abstract
H. annuus, more commonly known as the sunflower, is a single species that has many different variations. Traits have been selectively bred for hundreds of years in order to produce a beautiful flower as well as essential agricultural products. Recently interest in the sunflower as a food and fuel crop has led to selective breeding of seeds that produce high yields of sunflower oil. To further push the limits of this plant's genome, researchers have used mutagenesis to force mutations in hopes of developing novel modifications that could increase yield. With the entire genome mapped, the goal for many research groups is to create new genetic starting material for selective breeding. Chemical and radiation-based mutations have been shown to not only increase yield of useful lipid molecules but also create very bizarre looking appearances. This literature review poster discusses hybrid strains, mutant strains and methods of creating new modified genes to increase yields from this staple crop.
