    The degree of similarity of backcross lines of Triticum aestivum cultivars manitou and neepawa with Aegilops speltoides accessions as donors (1986)
    Springer
    Euphytica 35 (1986), S. 677-685 
    Details
    ISSN: 1573-5060
    Keywords: Triticum aestivum ; bread wheat ; backcross lines ; similarity Aegilops speltoides ; inhibitor gene
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary The degree of similarity of a BC line with its recurrent parent is not related to the presence of expressions for morphological characters originating from the donor like purple coleoptile, purple anther and waxy leaf. BC lines derived from one donor do not resemble each other more than they do other BC lines. The absence of characters conditioned by dominant or co-dominant genes may be caused by the presence of inhibitor genes.

    Groups of bread wheat landraces in Austrian alps (1989)
    Springer
    Euphytica 41 (1989), S. 235-246 
    Details
    ISSN: 1573-5060
    Keywords: Triticum aestivum ; bread wheat ; landrace groups ; classification ; primary landrace ; secondary landrace ; Austria
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary Using 49 morphological characteristics sixty-six accessions originating from 15 populations of bread wheat, together with 8 selections from landraces and 5 improved varieties were classified in five groups: group 1: Alpiner Bartwizen (including Hausbergweizen), Attergauer Bartweizen, which are marked by awned white ears; group 2: Awned Sipbachzeller (and its selection Otterbacher Bartweizen) and marked by awned red ears. This group also includes some awned derivatives of hybrids between group 1 and group 3; group 3: Sipbachzeller wheat, including Innviertler wheat and the selections Ritzlhofer Alt, Achleitner and Wieselburger roter Kolben; group 4: Tassilo and Tassilo-variants, and group 5: Dickkopf (Squarehead) types with lax ear, probably being derivatives of hybrids between group 3 and Dickkopf types. Most populations were contaminated with foreign material. The contamination may have been caused by the farmer who actually mixed varieties, or may have originated on the farmer's field.

    Classification of landraces and improved cultivars of hexaploid wheats (Triticum aestivum, T. compactum and T. spelta) grown in the USA and described in 1922 (1991)
    Springer
    Euphytica 59 (1991), S. 33-47

    ISSN: 1573-5060
    Keywords: Triticum aestivum ; bread wheat ; Triticum compactum ; club wheat ; Triticum spelta ; spelt wheat ; classification ; genetic diversity ; landraces ; cultivars ; USA
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary In 1922 Clark, Martin and Ball published descriptions of 207 hexaploid wheat landraces and improved cultivars, collected in the USA: 189 bread wheat accessions (Triticum aestivum), 24 club wheats (T. compactum) and four spelt wheats (T. spelta). After omitting 24 bread wheat accessions with identical descriptions as other accessions, the descriptions were used here to classify the remaining 183 accessions into five clusters on the basis of 10 selected characters. Clusters 1 and 3 include mainly accessions introduced from North and West Europe. These accessions must derive from the European Zeeuwse and Gelderse landrace groups. Hence most of the accessions belonging to these two clusters belong to the North and West European heritage. Cluster 2 includes most of the accesions introduced from Australia and Canada, or belonging to the club wheats. Most accessions from the USSR1 are included in cluster 4. Here we also find Turkey and related landraces. All but one pubescent accessions are included in cluster 5. The wide variation of US wheats, described in 1922, forms the basis of the Foundation Germplasm wheats as defined by Cox (1991). Apparently no hard white winter wheat landraces and cultivars were described.

    Classification of landraces and improved cultivars of rivet wheat (Triticum turgidum) and bread wheat (T. aestivum) from Great Britain and described in 1934 (1990)
    Springer
    Euphytica 47 (1990), S. 249-258

    ISSN: 1573-5060
    Keywords: Triticum turgidum ; rivet wheat ; Triticum aestivum ; bread wheat ; classification ; landraces ; improved cultivars ; Great Britain

    Notes: Summary Descriptions of landraces and improved cultivars of Triticum turgidum and T. aestivum grown in Great Britain, published by Percival (1934) were used to investigate between accession resemblance, and possible between accession relationships. It was found that the landrace accessions of T. turgidum belonged to one landrace and differed greatly from the bread wheat accessions. The bread wheat accessions also formed one group, but most landraces occurred at one side of the scatter diagram, and most cultivars at the other side. This distribution was mainly caused by the characters length and density of the ear. The improved cultivars had a shorter and denser ear than the landraces.

    The extent of similarity between near-isogenic lines of the Australian spring wheat variety Triple Dirk with their recurrent parent (1986)
    Springer
    Euphytica 35 (1986), S. 381-393 
    Details
    ISSN: 1573-5060
    Keywords: Triticum aestivum ; bread wheat ; near-isogenic line ; isogenicity ; phenotypic similarity ; vernalisation ; cold requirement
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary The near-isogenic lines of the wheat variety Triple Dirk supposed to differ only for Vrn genes have been investigated for their similarity to Triple Dirk and for purity. The NILs were found to differ from Triple Dirk. It was also discovered that Triple Dirk and the NILs each exist of more than one genotype. It is recommended that each NIL is tested for its Vrn-genotype and purified. New sets of Vrn NILs can only be made with these checked NILs and with one-plant progeny of the newly used recurrent parents.

    The degree of phenotypic similarity of near-isogenic lines of the wheat cultivar Centana with their recurrent parent (1989)
    Springer
    Euphytica 40 (1989), S. 161-167 
    Details
    ISSN: 1573-5060
    Keywords: Triticum aestivum ; bread wheat ; near-isogenic lines ; phenotypic similarity
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary The degree of phenotypic similarity of Centana and its near-isogenic lines (NILs) has been investigated. Some NILs have a disease reaction, a gliadin pattern and a yield level which differs from Centana. This means that they still possess many donor genes. One of the NILs, Shortana, must be a derivative of a backcross line crossed with an unknown genotype resulting in a good yielding variety.

    The degree of phenotypic resemblance of the near-isogenic lines of the wheat cultivar thatcher with their recurrent parent (1986)
    Springer
    Euphytica 35 (1986), S. 665-676 
    Details
    ISSN: 1573-5060
    Keywords: Triticum aestivum ; bread wheat ; near-isogenic lines ; phenotypic resemblance ; backcross ; linkage drag
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary Thatcher, 16 of its near-isogenic lines (NIL) and 8 donors were investigated for the degree in which the NILs phenotypically resembled their recurrent parent. In general the NILs have a good phenotypic resemblance. In a few NILs characters occur that are not seen in Thatcher. In some cases these are found in the donor indicating the presence of donor genes other than the marker gene in the NIL. In other cases a character possessed by a NIL is not present in Thatcher or in its donor. In such cases either inhibitor genes may play a part, or the donor accession that accompanies the set of NILs may not be the donor used to breed the NIL. Two causes are possible. One is that the donor was a mixture of genotypes, the other is contamination. The presence of donor genes other than the marker Lr gene(s) in a NIL may lead to unexpected results or, what is worse, to wrong conclusions.

    The character brown ear of bread wheat: A review (1983)
    Springer
    Euphytica 32 (1983), S. 299-310 
    Details
    ISSN: 1573-5060
    Keywords: Triticum aestivum ; bread wheat ; ear colour ; glume colour ; genetics ; linkage ; chromosomal location ; geographical distribution ; homeoallelic genes
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary A summary of the brown ear character of bread wheat is presented. In most varieties this character is conditioned by a (semi)dominant gene identified as Rg on 1BS. This gene seems to be widespread, from the viewpoint of evolution, probably because it is an ‘old’ gene. There are no indications that the presence of the gene and hence the presence of a brown ear is advantageous or disadvantageous to the carrier wheat plant. Some linkage relations are described. More research is needed to establish whether all varieties with one gene for brown ear carry Rg, to investigate the varieties with a non-monogenic genetic system and to identify more associations between brown ear and other characters. It should also further be investigated whether within T. spelta another gene for brown ear is present and, if so, whether this gene is on chromosome 1AS and linked to Hgl, the gene for hairy glume.
