Effect of parental genotypes on haploid embryo formation in wheat x maize hybridization
2005
Kondic-Spika, A. | Kobiljski, B.
Thirteen wheat (Triticum aestivum L.) combinations were crossed with two different maize (Zea mays L.) genotypes. The results have shown that there were significant differences among wheat combinations, as well as between maize genotypes in relation to the studied characters. Significant differences in fertilization frequency were found between pollinators in three wheat combinations (Banks/Rodna, Banks/NS-205-98 and Lira/Sonata). In these combinations, significantly better results were obtained in the crosses with Kelvedon Glory pollinator. The advantage of this pollinator was specially expressed in the frequency of haploid embryos, which ranged from 0.2 to 3.6; in relation to the total number of pollinated florets. In wheat crosses with ZPSC-213 pollinator, the frequency of haploid embryos ranged from 0 to 1.2;. No significant difference between the pollinators in regard of this trait was found in combination Banks/Rodna, while all other wheat combinations had significantly greater number of haploid embryos in the crosses with Kelvedon Glory pollinator.
