Abstract

We report on two methodologies for developing maternal haploids in Japanese pear.
In the first method, we tried to induce haploidization through an inter-generic hybridization with irradiated pollen of apple.
Fourteen seedlings germinated from 155 F₁ seeds that were sown.
Five seedlings at 120Gy total dosage (20Gy/h dose rate) and a seedling at 80Gy (10Gy/h) survived and grew vigorously.
Their morphology and DNA profiling indicated that they were similar to Japanese pear.
Secondly, we tried to obtain apomicts through an inter-generic cross between a specific cultivar of Japanese pear Gold Nijisseiki and apple with the intact pollen.
Only one seedling survived from the 53 inter-generic seedlings that germinated.
Its characteristics were also similar to the morphology of Japanese pear.
Though the individual did not inherit any RAPD markers from apple, it has two SSR alleles inherited from apple.
