Chemical compositions as quality parameters of ZP soybean and wheat genotypes

Abstract

This research is focused on the analysis of chemical characteristics of ZP soybean and wheat genotypes, as well as, on nutritional differences between this two complementary plant species. The experimental material consisted of two bread (ZP 96/I and ZP 87/Ip), two durum (ZP 34/I ZP and ZP DSP/01-66M) wheat genotypes and four soybean varieties (Nena, Lidija, Lana and Bosa) of different genetic background. All ZP soybean genotypes, except the Lana, had over 40% of total proteins by dry matter. Lana and Lidija, variety of recent creation, developed as a result of selection for specific traits, had high oil content. Wheat genotypes had much a lower content of ash, oil, total and water soluble proteins than soybean cultivars. The highest oil, total and water soluble proteins content was detected in grain of durum genotype ZP DSP/01-66M. Lignin content varies much more among soybean than among the wheat genotypes. Generally, contents of total phenolics, carotenes and tocopherol were more abundant in ZP soybean than bread and durum wheat genotypes.

Cilj ovog rada je analiza hemijskih karakteristika ZP genotipova soje i pšenice, kao i nutritivne razlike između ove dve komplementarne biljne vrste. Eksperimentalni materijal obuhvata dva hlebna, dva durum genotipa pšenice i četiri ZP genotipa soje različitog genetičkog porekla. Svi ZP genotipovi soje osim Lane, imaju preko 40% ukupnih proteina. Lana i Lidija, nedavno stvorene sorte, nastale kao rezultat selekcije za specifična svojstva, imaju visok sadržaj ulja. Genotipovi pšenice imaju znatno niži sadržaj pepela, ulja, ukupnih i u vodi rastvorljivih proteina nego genotipovi soje. Najviši sadržaj ulja, ukupnih i u vodi rastvorljivih proteina je nađen u durum genotipu ZP DSP/01-66M. Sadržaj lignina varira značajno više između genotipova soje nego pšenice. Generalno, sadržaj ukupnih fenola, karotina, i tokoferola je obilniji u ZP genotipovima soje nego u pšenici.
