dc.description.abstractVariability, heritability and components of variance have been studied in 50 cultivars from different selection centers all over the world. The experiment was performed in randomized block design in three replications on the experimental field during two seasons. A total number of 60 plants have been analyzed in the full maturity stage. The analyzed cultivars displayed very significant differences in the average value of plant height. The average variability of plant height was V=7.4%. The lowest variability of plant height was found in the Fundulea cultivar (V=5.2%), and the highest in Norin 10 (V=9.8%) cultivar. The obtained heritability value in broad sense was very high for plant height (h2=95.9%). Phenotypic analysis of variance indicated that there was a larger influence of genetic factors for plant height (84.32%) than influence of environmental factors on expressing of analyzed yield components.sr
dc.description.abstractU radu je proučavana varijabilnost, komponente fenotipske varijanse i heritabilnost za visinu biljke kod 50 genetički divergentnih sorti pšenice poreklom iz različitih selekcionih centara sveta. Istraživanja su obavljena u poljskom ogledu po slučajnom blok sistemu tokom dve vegetacione godine. Ogled je izveden po tipu ogleda retke setve (razmak od 20 cm između redova i 10 cm između biljaka u redu, sa dužinom reda od 1.0 m). U punoj fazi zrelosti pšenice urađena je analiza visine 60 biljaka u tri ponavljanja (3 x 20). Ustanovljene su visoko signifikantne razlike u prosečnim vrednostima između sorti za ovo svojstvo. Najveća prosečna visina biljke utvrđena je kod sorte Blue Boy (122.2 cm), a najmanja kod sorte Norin 10 (50.4 cm). Varijabilnost visine biljke bila je dosta niska, sa prosečnim koeficijentom varijacije od V= 7.4 %. Sorta Fundulea 262 (V=5.2 %) je pokazala najmanju varijabilnost za visinu biljke. Prosečna varijabilnost visine biljke bila je identična u obe godine istraživanja. Analizom fenotipske varijanse ustanovljen je visok udeo genotipa u ispoljavanju ovog svojstva (84.3 %), a znatno niži udeo godine (7.5 %) i interakcije sorta/godina (6.7 %). Takođe je utvrđena i visoka heritabilnost u širem smislu za visinu biljke (h2=95.9%). Sve analize ukazuju da na ispoljavanje visine biljke znatno veći uticaj imaju genetički faktori od faktora spoljne sredine.sr
