Morphological observations in durum wheat after embryo manipulations

Abstract

In cereals, haploid or diploid embryo structures are suitable organisations in practice for amelioration or storage of genotypes or some other biotechnologies. It is possible to reveal of variation as different genotypes from heterozygote or landraces after making homozygote of recessive alleles by doubling of chromosomes using embryo rescue. In these genotypes, characters can be evaluated as qualitative or quantitatively, for instance; dark purple coleoptile could be observed in some doubled haploid (DH) genotypes. The amount of chlorophyll (a/b) and carotenoid have been evaluated in young leaves in DH-6 and DH-8 and some other durum wheat genotypes, while investigating their tolerances to salinity in laboratory conditions. Colour of grains (amount of carotenoid in harvested grains) in durum genotypes have also been evaluated with field experiment conditions in three different locations of Anatolia and also correlation (r) has been identified with other grain characters related with agronomical values. Here it is possible to determine the rate into correlation (path) of characters and direct and indirect effects of each other. Naturally, the relationships between amount of chlorophyl in young leaves and carotenoid in harvested grains and also harvest index (HI) of genotypes will be able to be interesting subjects to discuss.
