Why doubled haploids?
Advantages of using doubled haploid plants in your breeding program are:
Production of 100% homozygous parent lines
More uniform parents are derived for hybrid seed production
Highly uniform offspring
Speeding up breeding progress (varieties are released much faster on the
market)
Faster anticipation towards demands of customers
Sorting out lethal genes in one step
Identification of recessive mutants
Creation of stable populations for genetic studies

Ploidy measurements with flow cytometry
Haploid, Doubled haploid and n≤2n mixoploids are difficult to identify by
morphology. Polyploids are often deformed.
