Scientific Short Article Response of Three Cold Tolerant Wheat (Triticum aestivum L.) Genotypes to Haploid Production Through Chromosome Elimination

To compare three wheat genotypes for producing the haploid and doubled haploid through chromosome elimination, an experiment was carried out using F1 population from the crosses RaptorxPishtaz, NorstarxPishtaz and MironovskayaxPishtaz. Measured traits were seed set percentage, embryo and haploid seedling development and were analyzed statistically using test. Among three genotypes, there was significant difference concerning the percent of seed and embryo forming, but significant difference was not observed for haploid plant. RaptorxPishtaz showed the highest value for seed set, MironovskayaxPishtaz the highest value for haploid plants and embryo forming percent, and NorstarxPishtaz the lowest level of haploid plants and embryo forming percent. According to the results, the seed set and embryo number traits, when the same number of florets are pollinated, can be considered as an important trait in genotype selection for production of doubled haploid plant. This experiment also showed the dependence of chromosome elimination trait to genotype.
