    Diversity of Evaluated Characters and HMW-Glu Alleles in Landraces and Cultivars of Emmer, Einkorn and Spelt Wheat

  • Original language description

    Morphological and agronomical characters were studied in emmer (22), einkorn (10) and spelt (10) wheat cvs. in two seasons in Prague. Large diversity was recorded especially in emmer wheat, followed by einkorn and spelt. Spelt and emmer had tall stem (mean =115 and 107 cm respectively). Einkorn was shorter (85 cm), with good resistance to powdery mildew but low values of productivity characters. High spike productivity in spelt (mean grain mass per spike = 1.59 g) was conditioned by high TGW (mean 49 g), lower spike productivity was in emmer (mean 0.86 g, best cultivar 1.47 g). HMW Glue allele 2* at 1A chromosome was rare in bread wheat (7%), absent in spelt and frequent in emmer (36 % lines), allele 1 was prevailing in all species. At 1B, most commonin wheat were subunits 7+9 (40%) and 7+8 (22 %). Combination 6+8 was frequent in spelt (76%) and alleles 7+8 (41%) and 21 (21%) in emmer where also some rare alleles were found. Diversity of HMW- Glu subunits at 1D was lower.

    Diverzita hodnocených vlastností a HMW Glu alleles krajových odrůd pšenice, pšenice špaldy, jednozrnky a dvouzrnky

  • Czech description

    U souboru odrůd pšenice jednozrnky (10) dvouzrnky (22) a špaldy (10) byly studovány morfologické a agronomické vlastnosti ve dvou sezonách v Praze. Vysoká diverzita byla zaznamenána specielně u dvouzrnky, následovala jednozrnka a špalda. Špalda a dvouzrnka měly vysoké stéblo (průměr =115 and 107 cm). Jednozrnka byla kratší (85 cm), s dobrou odolností k padlí. Pšenice špalda se vyznačovala vyšší produktivitou zrna v klasu (průměrná hmotnost zrna na klas = 1.59 g) na rozdíl od dvouzrnky (průměr 0.86 g, nejlepší odrůda 1.47 g). HMW Glu alela 2* na 1A chromosomu v pšenici obecné se vyskytovala zřídka (7%) , ve špaldě se tato alela nevyskytla a nejfrekventovanější byla v dvouzrnkách (36 % linií), alela 1 převažovala ve všech druzích. Na chromozomu 1B, bylau pšenice nejběžnější gluteninová podjednotka 7+9 (40%) a 7+8 (22 %). Kombinace 6+8 byla čatá ve špaldě (76%) a alela 7+8 (41%) a 21 (21%) v dvouzrnkách. Diverzita HMW-gluteninových podjednotek na chromozomu 1D byla nižší.
