EFFECT OF 1B/1R TRANSLOCATION ON PROTEIN COMPLEX AND RELATIVE VISCOSITY OF WHEAT GRAIN WITH EMPHASIS ON FEEDING VALUE

Result description

The research was aimed at a 1B/1R translocation effect on selected grain parameters of wheat double haploid (DH) lines. A set of DH wheat lines selected according to the presence (8 lines) or absence (10 lines) of 1B/1R translocation was grown for 3 years. There were tested following parameters of grain: content of crude protein, content of 9 selected essential amino acids, calculated essential amino acid index (EAAI), protein fractions content (albumins + globulins and their proportion in crude protein; gliadins and sum of glutenins) and relative viscosity. There were found out higher genotypic dependence of albumins+globulins content and relative viscosity in comparison with content of crude protein, gliadins, glutenins and amino acids. There was also confirmed high positive correlation among most of essential amino acids, crude- and storage proteins (gliadins and glutenins) and their negative correlation to proportion of albumins+globulins in crude protein. The parameter EAAI did no

    Vliv 1B/1R translokace na bílkovinný komplex pšeničného zrna a relativní viskozitu s ohledem na krmnou kvalitu

  • Czech description

    Výzkum byl zaměřen na vliv 1B/1R translokace na vybrané parametry zrna u dihaploidních (DH) linií pšenice. Soubor DH linií členěných podle přítomnosti (8 linií) či absence (10 linií) 1B/1R byl pěstován po 3 roky. Byly u něho hodnoceny následující charakteristiky zrna: obsah hrubých bílkovin, obsah 9 vybraných esenciálních aminokyselin, vypočtený index esenciálních aminokyselin (EAAI), obsah bílkovinných frakcí (albumino-globulinové frakce a její podíl v hrubých bílkovinách; gliadiny a suma gluteninů) arelativní viskozita. Byly zjištěny větší rozdíly mezi genotypy v obsahu albumino-globulinové frakce a v relativní viskozitě ve srovnání s obsahem hrubých bílkovin, gliadinů, gluteninů a aminokyselin. Byla potvrzena silná pozitivní korelace mezi obsahem většiny esenciálních aminokyselin a obsahem hrubých a zásobních bílkovin (gliadinů a gluteninů) a jejich negativní korelace k podílu albuminů a globulinů v hrubých bílkovinách. U EAAI nebyla prokázána průkazná závislost na více variabilníc
