SADAF- A POTENTIAL DONOR FOR ENHANCING FREQUENCY OF DOUBLED HAPLOIDS IN WHEAT × MAIZE CROSSING SYSTEM

To identify the genotypic effects of parents for wheat × maize crossing system, five f1 wheat genotypes were crossed with five maize cultivars. the data for haploid seed and embryo production in each cross was recorded and analyzed. the data revealed that maize genotypes have significant variable effects on haploid wheat seed and embryo production. the line × tester analysis proved that wheat and maize genotypes along with their interactions, affect haploid seed and embryo production in wheat × maize crossing system. in this experiment a maize variety named sadaf showed best performance on the basis of high gca value as compared to others. it was also discovered that high seed production phenomenon could not be associated with high haploid embryo formation in a wheat × maize crossing system. it was concluded that maize genotypes having great potential for wheat haploid production should be identified and utilized in this system to improve its efficiency as in this study sadaf is recommended for wheat × maize crossing system.
