“…Similarly, for maize and potato, embryo production and plant regeneration ability from anther culture were not correlated (Dieu & Beckert, 1986 ;Meyer et al ., 1993), indicating also that these traits `depend on different types of gene action' . Similar evidence was obtained from somatic embryogenesis experiments, and it has been demonstrated that callus induction rate and regeneration ability are controlled by independent genetic systems in wheat (Chowdhury et al ., 1991) and barley (Komatsuda et al ., 1989) .…”

The in vitro development of a whole plant from a single cell (eg microspore or somatic cells) is a characteristic feature of plants . The amenability of a plant to in vitro culture is influenced by the genotype, which is thus of major importance in the plant tissue culture response . The differences observed between different cultivars during in vitro tissue culture with respect to embryogenesis and regeneration result from quantitative or qualitative genetic differences . We describe results obtained from quantitative genetic studies, from Mendelian genetic analysis and from gene mapping . It is less easy to study the influence of cytoplasmic genomes . Moreover, it is necessary to discriminate between maternal effects and cytoplasmic inheritance . A conclusion from this review is that the choice of parental strains for a breeding program should be realized on agronomic criteria rather than on compatibility with the tissue culture technique used . Fortunately, it is relatively easy to incorporate short-term tissue culture capacity into agronomically valuable genotypes . This is of major interest since tissue culture remains necessary for most aspects of crop plants biotechnology . Very little is known about the molecular events that trigger in vitro embryogenesis and regeneration . It is clear that genes involved in the tissue culture response are not specialised tissue culture genes' .

“…Many researchers found the variability of a tissue culture response of immature embryos in wheat (Sears and Deckard 1982;Chowdhury et al 1991;Machii et al 1998;Varshney and Altpeter 2002;Haliloglu et al 2005). It has become evident that a genotype used was of a major importance in the plant tissue culture response, although donor plant environment conditions and a culture medium composition have been considered as important factors too (see review of Sahrawat et al 2003).…”

There are only a few reports about the relationship between tissue culture and agronomic traits in wheat. In an attempt to enlarge the knowledge in this area, 96 wheat genotypes of worldwide origin were evaluated for their tissue culture response as well as the agronomic performance in the threeyear field trials. Plant regeneration was achieved from immature embryos collected 12-15 days after anthesis. Associations between tissue culture and agronomic traits were surveyed by the correlation and path coefficient analyses. A trait-association by year biplot was applied to understand environmental effects on these relationships. All significant traitassociations were of a moderate magnitude and were responsive to the environment. The path coefficient analysis revealed that a grain yield had the highest positive direct effect on a callus formation while the kernel number per spike had the highest positive direct effect on regenerative calli and plant number per embryo. Nevertheless, only productive tillering had significant (positive) direct effect on all studied tissue culture traits.

SummaryIn this study, karyotype criteria of 14 genotypes of Triticum aestivum L. in addition to one genotype of Triticum durum Desf. are described and polyploid variations are discussed. Detailed karyotype features, i.e. total chromosome length (TCL), mean chromosome length (MCL) and karyotype asymmetry expressed as arm ratio (MAR), total form percent (TF %), intrachromosomal asymmetry (A 1 ) and interchromosomal asymmetry (A 2 ), are also described.
