dc.description.abstractU radu su ispitivani genetički odgovori i fenotipske promene kod tri domaće divergentnesorte pšenice: PKB Talas, BG Merkur i PKB Lepoklasa, tokom procesa sortnereprodukcije. Ispitivanja su obavljena u dve proizvodne godine, 2008/2009 i 2009/2010,u poljskim ogledima na eksperimentalnim poljima Instituta PKB Agroekonomik.Ispitivana su po tri različita tretmana (varijante) za svaku od ovih sorti u pogledu primeneselekcije i gustine useva, koji odgovaraju zahtevima za proizvodnju tri različite kategorijesemena: elita, original i prva sortna reprodukcija. Biljke u svakom od različitihproizvodnih uslova su praćene uz merenje njihovih fenotipskih karakteristika. Poobavljenoj žetvi ispitivan je kvalitet njihovog semena, tehnološke osobine i ocenjivananjihova sortna identičnost primenom laboratorijskih metoda i tehnika. Dobijeni podaciobrađeni su biometrijski i prikazani kroz odgovarajuće tabele, grafikone i slike. Ukupno uanalizu je uključeno 5400 podataka (100 biljaka x 3 ponavljanja x 3 varijante ogleda x 3sorte x 2 godine) za svaku ispitivanu morfološku osobinu biljaka (broj izdanaka, brojklasića u klasu, broj zrna u klasu, apsolutna masa zrna i masa zrna u klasu). Izračunate susrednje vrednosti (M) i varijabilnosti (varijanse i koeficijenti variranja) za sve ispitivaneosobine pšenice, kao i značajnosti njihovih razlika primenom LSD - testa. Na osnovuprosečnih vrednosti ispitivanih sorti pšenice u obe ispitivane godine sorta PKB Talasimala je najveće vrednosti sledećih ispitivanih osobina: broj izdanaka (3,26) i broj klasićau klasu (21,66), dok je sorta PKB Lepoklasa imala najveće prosečne vrednosti za ostaleispitivane osobine: broj zrna u klasu (69,98), apsolutna masa zrna (45,22 g) i masa zrna uklasu (3,17 g). Sličnosti i razlike između fenotipskih osobina sorti, po varijantama igodinama, određene su primenom hijerarhijske klaster analize, koja je pokazala da susorte PKB Talas i BG Merkur relativno sličnijih osobina, nego sorta PKB Lepoklasa kojase izdvojila po svojim osobinama. Uticaj sorte pri grupisanju (klasterovanju) bio je jačinego uticaj semenske kategorije. Kategorije semena original i prva sortna reprodukcija (ISR) daju sličnije fenotipove međusobno u odnosu na kategoriju semena elita. Najjače korelacione zavisnosti utvrđene su između osobina broj izdanaka i broj zrna u klasu (r =0,96), kao i između osobina broj izdanaka i masa zrna u klasu (r = 0,93) kod sorte PKBLepoklasa...sr
dc.description.abstractGenetic responses and phenotypic changes in three divergent domestic wheatcultivars during the process of varietal reproduction were examined in this paper: PKBTalas, BG Merkur and PKB Lepoklasa. Tests were conducted in two production years2008/2009. and 2009/2010., in field trials in the experimental fields of the Institute PKBAgroekonomik. Three different treatments (variants) were tested for each of thesevarieties in terms of selection and plant density, corresponding to the requirements for theproduction of three different categories of seeds: the elite, the original and first certifiedreproduction. Plants in each of the different production conditions were monitored bymeasuring their phenotypic characteristics. Upon completion of the harvest quality oftheir seeds, technological properties and evaluated their varietal identity were tested usinglaboratory methods and techniques. The obtained data were biometricly processed anddisplayed through the appropriate tables, graphs, and images. 5400 data (100 plants x 3replications x 3 testing variants x 3 cultivars x 2 years) were included in analysis for eachmorphological characteristics of plants (number of secondary tillers, number of spikeletsper spike, number of grains per spike, weight per 1000 seeds and weight of grain in theear). Mean (M) and variability (variance and coefficients of variation) were calculated forall characteristics of wheat, and the significance of their differences using LSD test. Talascutivar had the highest values based on the average values of tested cultivars in bothyearsof the following characteristics: number of secondary tillers (3,26) and number ofspikelet per spike (21,66), while variety PKB Lepoklasa had the highest average valuesfor other characteristics: number of grains per spike (69,98), weight per 1000 seeds(45,22 g) and weight of grain per spike (3,17 g). Similarities and differences between thephenotypic characteristics of cultivars, the variants and years are calculated using thehierarchical cluster analysis, which showed that the cultivars PKB Talas and BG Merkurhave relatively similar characteristics, related to PKB Lepoklasa cultivar that split it`s characteristics...en
