Abstract
Grain quality parameters of five new maize inbred lines were investigated and compared with the corresponding properties of two commercial hybrids used in flour production.Kernel of the line L2 had the highest 1000-kernel mass (267.54 g), and line L2 had the highest test mass (844.68 kg m-3).The milling response ranged from 9.80 (L2) to 14.03 s (L1). The largest share of the soft fraction of endosperm was determined in L3 (37.13 %), which is slightly lower than in hybrid ZP 633. The highest protein (12.37 %), as well as crude fibre content (2.59 %) was determined in inbred line L4, while the lowest protein was found in the line L2 (9.36 %), and the lowest crude fibre content (1.81 %) was detected in line L3.All tested maize inbred lines were found to be highly prospective for breeding of new hybrids with improved grain quality parameters
Kukuruz (Zea mays L.) predstavlja jednu od najviše gajenih i najznačajnijih žitarica koje se vekovima koriste u ishrani ljudi i životinja. Cilj ovog istraživanja bio je da se ispitaju novi genotipovi kukuruza sa povećanim potencijalom za stvaranje komercijalne kategorije semena visoke nutritivne, funkcionalne i tehnološke vrednosti koje bi imalo povoljne karakteristike mlevenja za proizvodnju integralnog kukuruznog brašna. Ispitivani su parametri kvaliteta zrna pet novih samooplodnih linija kukuruza i upoređivani sa odgovarajućim svojstvima dva komercijalna hibrida koja se koriste u proizvodnji brašna. Zrno linije L2 imalo je najvišu apsolutnu masu zrna (267,54 g), a zrno linije L2 najvišu nasipnu masu (844,68 kg m-3). Otpornost na mlevenje kretala se od 9,80 (L2) do 14,03 s(L1). Najveći udeo meke frakcije endosperma utvrđen je u liniji L3 (37,13%), što je nešto niže nego u standardnom hibridu zubanu ZP 633 (41,97%). Najviši sadržaj proteina (12,...37%), kao i sirove celuloze (2,59%) određen je u liniji L4, dok je linija L2 imala najniži sadržaj proteina (9,36%), a linija L3 najniži sadržaj sirove celuloze (1,81%).Utvrđeno je da sve ispitane nove samooplodne linije kukuruza poseduju visok potencijal za selekciju novih hibrida sa poboljšanim parametrima kvaliteta zrna.
