Reflections on doubled haploids in plant breedingplants have also been referred to as dihaploid plants, however, the classical definition of dihaploid is the haploid plant (1. = 2.) of an autotetraploid (2. = 4.). To avoid confusion, doubled haploid is preferred to dihaploid.

Haploids in plant breedingn the pollen grain. The haploid embryo can arise from an egg cell (gynogenesis) or from a gametophytic cell other than the egg cell (apogamy) or a male gamete (androgenesis). It can also originate from the microspore nucleus before first pollen grain mitosis when pollen or anthers are cultured .. Ha

Reflections on doubled haploids in plant breeding) from heterozygous parents, and 2. doubling the chromosomes in the tissues (followed by regenerating plants) or plants to obtain diploid plants (2.) which are referred to as doubled haploids. At the haploid level, every gene is hemizygous. After chromosome doubling, which in theory makes an identic
