Development of secondary tetraploid triticale with a complete A-genome through crossing primary amphiploids with secondary hexaploid triticale
2000
Sodkiewicz, W. | Apolinarska, B.
The AmAmRR wheat-rye amphitetraploids obtained in the result of crossing diploid wheat T. monococcum with rye are self-sterile but their gametes, both female and male, are functional. Efforts were undertaken to cross such forms with hexaploid triticale with the aim to study frequency of the substitution of chromosomes from genome B to primary allotetraploid genotypes and, further in doing so, to ascertain possibilities of creation of secondary AARR forms with aestivum cytoplasm. The obtained results revealed a complete absence of chromosome transfer from genome B to the developing forms with secondary tetraploid despite a well known reduced conjugation capability of some diploid...
