PREDICTION OF TECHNOLOGICAL QUALITY OF WHEAT BASED ON GENETIC MARKERS

Popis výsledku v původním jazyce

The importance of wheat with different grain colour in practice is increasing, mainly of those with purple pericarp and blue aleurone. Higher amount of phenolic compounds especially anthocyanins with demonstrable antioxidant effects make this wheat different from a standard wheat varieties. The research based on molecular methods with the use of PCR deals with detection of the allelic composition of Glu-1 loci of high molecular weight glutenin subunits (HMW-GS) and presence or absence verification of secalin locus (Sec-1). For our research 8 wheat genotypes with blue aleurone and one genotype with white grain were used. At the respective loci these subunits and their combinations were identified: Glu-A1 (Ax1, Ax2*, AxNull), Glu-B1 (Bx7+By8*, Bx7*+By8, Bx7*+By20*, Bx7+By20*, Bx6+By20*), Glu-D1 (Dx5+Dy10). Subunits Ax1, Ax2* and allelic combination Dx5+Dy10 are considered as markers of good bread-making quality. The presence of allele Glu-D1d which is a marker of good bread-making grain quality was proved in genetic resources with blue aleurone UC66049, Skorpion (RU 440-6) and RU 440-5 and they are therefore considered as perspective. The rye translocation 1BL/1RS was absent in the whole studied collection. Blue grain genotypes Barevna 9 and Barevna 25 showed higher resistance to fusarium head blight.
