Abstract
Six selected bread wheat double haploid genotypes and eight maize cultivars belonging to four types were used in this study. The six wheat genotypes pollinated with the eight maize cultivars to study the effects of different maize genotypes of distinct types on the wheat haploid embryo ratio. The results showed that the same wheat material when pollinated with different maize cultivar, the embryo rate differed between 1.5 to 3 times and ranging from 15.43% to 47.80%. The average haploid embryo induction rate was highest in sweet type (33.24%) and lowest in super sweet type (29.59%). The wheat genotype A6 recorded the highest embryo rate percentage (34.11%), while A5 recorded the lowest rate (29.36%). The white Sweet Waxy (B4) found to be the highest for embryo rate, followed by the Cloud Sweet Jade 6th (B5) and Jane wo Waxy 1th (B1), while the lowest was recorded by Cloud Super Sweet 2nd (B8) cultivar. The maize genotypes in the same type differed significantly regarding the haploid embryo induction rate of wheat genotypes and thus maize types were not consistent in their behavior. So, the key was to select maize genotypes and not the maize type. The interaction between wheat genotype and maize genotype has a significant effect on the embryogenesis rate. Therefore, if the rate of embryo induction of some wheat materials with a common maize variety is low, it may be possible using the pollination of other maize cultivars to increase the embryogenesis in wheat x maize hybridization.
