Research and utilization of poly-haploids in wheat has been limited because of the low frequency of haploid formation. In haploid production through wheat x maize crossing, application of hormones is crucial to produce embryos. Effect of different hormones and application methods were studied in wheat x maize crosses. The wheat genotypes and methods of hormonal treatments viz. spray and tiller injection exhibited highly significant differences for embryo formation. Different hormonal treatments viz. 100 ppm 2, 4–0, 100 ppm GA₃ and 100 ppm AgNO₃ differ significantly for per cent seed set and embryo formation.
