Genetic analysis of rye (Secale cereale L.) Genetics of male sterility of the G-type

Abstract

The genetics and relationships between the genes in rye located in the nucleus and cytoplasm of the male sterility of the G-type were investigated. A factor inducing male sterility was found in the cytoplasms or rye cv Schlägler alt and rye cv Norddeutscher Champagner. Monogenic inheritance was observed in linkage tests. Using primary trisomies of rye cv Esto, the nuclear gene ms1 was found to be located on chromosome 4R. Modifying genes, probably masked in normal cytoplasm but expressed in male-sterility-inducing cytoplasm together with gene ms1, were located on chromosomes 3R (ms2) and 6R (ms3). Mono-, di-, and trigenic inheritance types were found in backcross progenies of trisomies.

RAPD markers linked with restorer genes for the C‐source of cytoplasmic male sterility in rye (Secale cereale L.)

“…A weak restorer gene for the G cytoplasm was also identified on the 6R chromosome by means of trisomics analysis (Melz and Adolf 1991). This result is consistent with the suggested localization of two RAPD markers (pr777/600 bp and pr433/ 800 bp) on the 6R chromosome.…”

“…The existence of at least three loci for male sterility in cms-C cytoplasm is expected. Assuming that cms-G and cms-C cytoplasms are very similar (Warzecha and Salak-Warzecha 1996), it is reasonable to suggest that, except for the two genes on chromosomes 4R and 6R identified in this study, another locus for male sterility could be positioned on chromosome 3R (Melz and Adolf 1991).…”

“…In addition, two modifying genes were located on 3R and 6R (Melz and Adolf 1991). Male fertility in the sterilizing C cytoplasm was connected with at least three independent loci (Łapin´ski 1990).…”

“…A major restorer gene for G cytoplasm was mapped on the distal part of the 4RL chromosome arm (Bo¨rner et al 1998). In addition, two modifying genes were located on 3R and 6R (Melz and Adolf 1991). Male fertility in the sterilizing C cytoplasm was connected with at least three independent loci (Łapin´ski 1990).…”

Combining ability of non‐adapted sources for male‐fertility restoration in Pampa CMS of hybrid rye*

“…Łapin´ski and Stojałowski (2001) found that the vast majority of male sterility sources from 50 rye populations belonged to the Vavilovii type. This also holds true for the G cytoplasm (Melz and Adolf 1991) that was used to produce a hybrid variety in Germany in 2000 (ÔNovusÕ).…”
