Summary
The anthers of three F1 hybrids of hexaploid triticale and common wheat (‘Rosner’ X ‘Kedong 58’, ‘Beagle’ X ‘Kedong 58’ and ‘Beagle’ X ‘Jinghua No. 1’) were cultured on four media in vitro. More than 900 green plants were obtained. The chromosome numbers ranged from 17 to 27 for haploid derivatives and from 38 to 52 for diploid regenerates. The chromosome constitutions of the pollen plants reflect those of the gametes found in the donor plants (genome formula: AABBDR). The value of such pollen plants for genetical analysis of rye wheat addition and substitution lines, as well as for breeding purposes, is discussed.
