“…sativa and one for L. serriola (Bennett and Smith 1976, quoting To the knowledge of the writers there is no published account of different DNA amounts per nucleus being found in different cultivars of L. sativa , although a single absolute determination of DNA amount in one variety has been recorded (McLeish and Sunderland 1961). However such differences found in the present work , are in accordance with the findings of other workers between cultivars of other species (e. g. Avanzi et al 1966 in Tritcum durum, Furuta et al 1975 in 27 strains of Aegilops squarrosa, Ahmad and Godward 1980 in two cultivars of Cicer arietinum , Price et al 1980 in Microseris douglasii, Resslar et al 1981 in Arachis. ) However there are accounts (e.g.…”

“…The ratio between A and D genomes of common wheat was 1.00:0.88 that is very close to the ratio observed between two genome donor species, T. monococcum (A genome) and Ae. squarrosa (D) by Furuta (1975). Furuta et al (1974) and Nishikawa 'et al (1979) confirmed that DNA content of AABB genome component extracted from three cultivars of common wheat is equal to that of Emmer wheat.…”

In order to elucidate the origin of tetraploid wheat, nuclear DNA content (1C or 4C) in eight accessions of Triticum urartu, 21 of four Sitopsis species of genus Aegilops and three artificial tetraploids obtained from the F1 hybrid between Ae. longissima, Ae. sharonensis or Ae, bicornis and T. monococcum was measured by means of Feulgen-cytophotometry.T, urartu showed uniform DNA content among the accessions, and was the same DNA as T. monococcum in its DNA content. Some intraspecific variation was noticed in three species, Ae. ton gissima, Ae. sharonensis and Ae. searsii. Whereas two other species, Ae. spelt oides and Ae. bicornis did not show any significant intraspecific variation. 4C DNA content in three synthesized tetraploids was the same as the sum of the contents of their parents' and was nearly equal to that of Emmer wheat, indicating that all Ae. ton gissima, Ae, sharonensis and Ae. bicornis can be a candidate of the B genome donor to polyploid wheat. On the other hand, T, urartu and Ae. speltoides have less DNA content than the B genome of polyploid wheat.

“…In relation to phylogeny of wheat, several comparative studies of nuclear DNA content have been reported (Rees 1963;Rees and Walters 1965;Pegington and Rees 1970;Nishikawa and Furuta 1968,1969Furuta 1975;Furuta et al 1974Furuta et al , 1977Furuta et al ,1978Nishikawa et al 1979). They are summarized as follows; 1) with the exception (T, monococcum, Ae.…”

In order to consider at chromosomal level the phylogeny of wheat, DNA content of 21 individual chromosomes was measured cytophotometrically at Ml or Al of meiosis in inonosomic plants and compared among seven strains belonging to six subspecies of common wheat, Triticum aestivum. 1) Nuclear DNA content at pollen tetrad did not differ at all among seven strains.2) DNA content of individual chromosomes varied from chromosome to chromosome in any strain.3) Significant difference was found among three genomes, A, B and D, the ratio being 1.14: 1.21:1.00.This ratio apparently differed from those of two earlier reports based on nuclear DNA content of putative diploid ancestors (T, monococcum: Aegilops speltoides: Ae. squarrosa). The authors suggested diploid species of section Sitopsis, with a little higher DNA content than Ae. speltoides as B genome donor to polyploid wheat. 4) There was not significant difference among seven homoeologous groups, but homologous chromosomes. 5) Total DNA content of seven strains calculated from DNA content of individual chromosomes was very similar to one another, being clearly compatible with the results of nuclear DNA content at pollen tetrad.
