Abstract
Merely two tetraploid rye plants were found among 128 progeny plants of four F1 hybrids between tetraploid triticale (2n = 28) and tetraploid rye (4n = 28). The remained plants were triticales, tetraploid with exception of one individual with 38 chromosomes. The numbers of wheat and rye chromosomes were precisely determined, with the Giemsa banding technique, for 57 plants, including 32 true F2 obtained following the F1 selfing. Over 90% of the tetraploid triticales had full complement of 14 wheat chromosomes, in the remained plants one or two wheat chromosomes were substituted for the rye ones. The substitution plants with a higher proportion of rye chromosomes were lacking. There were also no cases of new intergenomic translocations different to those present in the parental forms. In relation to the theoretical distribution, based on the assumptions on independent segregation for wheat-rye pairs of homoeologues and on equal survival of all types of gametes and zygotes, the over-representation of the plants with 14 wheat chromosomes was 16000 — fold. The influence of a mistake at crossing could be excluded because of the normal segregation of a cytogenetically marked version of the 1R rye chromosome from the rye parent. Owing to a relatively high fertility of the F1 generation (40–45 seeds per spike), the over-representation of triticales with the whole wheat genome could not be statistically explained by zygotic or/and gametic selection. The results suggest group segregation of wheat chromosomes in meiosis, rather than of the assumed independent segregation of each wheat-rye pair. The low frequency of rye plants could be related to self-incompatibility of karyotypes without the complement of wheat chromosomes.
