Vagera, J.; Nesvadba, Z.; Martinek, P.; Ohnoutková., L.: In vitro haploid zygotic embryogenesis due to pollination with maize pollen and induced in vitro androgenesis in Czech wheat breeding genotypes. Rostlinná Výroba, 47, 2001, 5:293-2000

Original language description

Induction of haploid zygotic embryogenesis and androgenesis was studied in 72 and 31 wheat genotypes, respectively. Green zygotic plants (haploids only) were obtained in 52 genotypes (72 %), and green androgenic regenerants (haploids and spontaneous polyhaploids) were observed in 17 genotypes (55 %). In zygotic embryogenesis embryos developed in 65 genotypes (90 %), and in androgenesis embryos or microsporial calli were detected in 28 genotypes (90 %). The highest frequency of haploid zygotic regenerants was 0.24 per pollinated flower, whilst that of androgenic regenerants was 0.08 per cultured anther (0.24 per three anthers in one flower). On average, in induced androgenesis the plants were produced by one out of three androgenic anthers. In induced haploid zygotic embryogenesis the plants were regenerated by every third flower (ovary) with induced embryos. In a set of selected genotypes the yield of induced haploid zygotic embryogenesis was compared with induced pollen embryogenesis.
