Effect of wheat and maize genotypes for wheat haploid production in wheat x maize crosses

Abstract

The hybridization of wheat x maize has emerged as the most efficient technique for wheat polyhaploid production, having several advantages over other methods of wheat haploid production [1]. Despite considerable research in the area of wheat x maize system of haploid production, there is, however, still controversy surrounding the differential effect of wheat and maize genotypes on the success of haploid plant production. Whereas some groups reported a significant influence of maize genotype on the success of haploid plant production [2, 3], others report differences in crossability dependent only on wheat genotypes [4, 5].
