Advantages of Haploids - 1. Production of homozygous DH lines using haploids saves at least 4 years in comparison to selfing/close inbreeding.

2. Selection among DH lines is at least 6-8 times as efficient as that among segregating populations; this greatly reduces the size of breeding populations,

3. Haploids may be useful for the isolation of mutants, since even recessive mutant alleles will express in the M1 (mutagen-treated) generation itself.

4. Pollen embryos are generally highly regenerative. Therefore, they can be used for gene transfers mediated by Agrobacterium or by a technique like particle gun.
