Abstract:

In this study, it was aimed to determine the haploidy frequencies of the some locally grown onion (Allium cepa L.) genotypes in Turkey by flower bud culture. The effect of genotype on callus formation, callus transformation to plants and direct plant formation was found to be statistically significant. In the experiment, 39 plants were obtained from calluses and direct plant growth from flower buds. Ploidy analysis revealed that one of these plants, genotype number 13 obtained from (Siverek/?anl?urfa province), was haploid. Compared to others, genotypes 12, 13 and 5 were found to have high ability on both callus formation and direct plant formation. Therefore, it is thought that these genotypes can give more successful results in haploid plant production in onion breeding studies
