Identification of five new primary simple primary trisomics
in soybean based on pachytene chromosome analysis.
Chromosomal location of fertility restoring genes for `wild abortive' cytoplasmic male sterility using primary trisomics
Therefore, the triploids from ms1ms1 soybean have not become useful sources for generating primary trisomics
(2n = 2x + 1 = 41) in soybean.
, and other chromosome number variants for the group-1 chromosomes were observed.
In the near future, we anticipate the availability of all 20 primary trisomics
of soybean (Xu et al., 1997).
The extent of morphological variations observed in MAALs reported in this study could not be compared with the primary trisomics
of the soybean at this time because all the soybean primary trisomics
are in a heterozygous genetic background.
Chromosome location of two isozyme loci in Lolium perenne using primary trisomics
However, a low occurrence of primary trisomics
were observed (Table 2) as well as a single tetraploid.
The F1 hybrids were trisomics
and the succeeding progenies were highly sterile.
A high frequency (19%) of deletions was detected compared to other chromosome aberrations such as monosomics, trisomics
and translocations (12% each).
Production and identification of primary trisomics
in diploid Agropyron cristatum (crested wheatgrass).
