Abstract

This study aimed to assess the efficacy of silver nitrate and calcium phosphate in inducing chromosome elimination and promoting haploid wheat generation in the context of wheat-maize crosses. The experiment explored the impact of various treatments, including non-use (control) and the utilization of silver nitrate (3gr/l) combined with calcium phosphate (0.1gr/l). Additionally, different durations of treatments post-pollination, spanning 48 and 72 hours, were considered. The study evaluated key characteristics such a number florets, number as well as the quantity and percentage of successful seed formations. The findings underscored significant distinctions among the treatments, achieving a level of significance of 1%. The use of silver nitrate in conjunctionwith calcium phosphate for wheat tillers demonstrated an increased propensity for haploid embryo formationSpecifically, maintaining wheat tillers in a solution of silver nitrate and calcium phosphate for 72 and 48 hours, in comparison to the control group, resulted in haploid embryo formations with proportions of 12.53%, 5.60%, and 3.82%, respectively. These results indicate that extended exposure to the silver nitrate-calcium phosphate treatmentenhances the formation of haploid embryos.
