Abstract

Wheat (Triticum aestivum L.) haploids were produced by crossing with Job's tears (Coix lachryma-jobi L.) as the pollen parent. Pollination was followed by 2,4-D treatment, detached tiller culture, and embryo culture, as described for maize pollination. The frequency of embryo formation was similar to that obtained by crossing wheat with maize pollen. Job's tears is a perennial plant which forms several stalks and its pollen can be collected throughout the year when the plant is maintained in a controlled environment. Our results indicate that Job's tears can be used as the pollen parent for wheat crosses for haploid production without requiring synchronization of flowering dates.
