Evaluation of Spontaneous Genome Doubling Ability in Haploids of Diverse Genetic Background

Authors: Ursula Frei (Iowa State University) , Nick Boerman (Iowa State University)

Abstract

Doubled haploid (DH) technology using in vivo haploid induction has found wide application in corn breeding in the past decade. Progress has been made to overcome the major bottlenecks of the technology: low haploid induction rates, labor-intensive manual haploid selection, and low doubling rates after chemical treatment for chromosome doubling. However, haploid genome doubling rates remain a major limiting factor in the successful production of DH lines in maize.
