dc.description.abstractThe aim of this study was to determine which of six inbreeds that were investigated could be the donor of the favorable alleles for grain yield and its components ear diameter and number of kernels in a row. The trial including the F1 hybrid progeny and the inbreeds investigated was set in 1998 in RCB design at four locations: Zemun Polje, Srbobran, Pančevo and Inđija, in four replications. The modified method after Dudley (1987) was used to establish the donors of favorable alleles. All inbreeds expressed positive values of the UG parameter and the L545-93 inbred line was chosen to improve the grain yield of the ZPE25-10-1 x B84 elite hybrid on the basis of the largest value of its UG parameter (0.95*). Positive UG values were determined for other investigated traits, e. g. the ear diameter (0.26*) and the number of grains in a row (2.54*), also. On the basis of the relative relatedness of the L545-93 inbred and the parents of the elite hybrid it was concluded that the parallel improvement of the ear diameter and the kernel number in a row could be achieved by backcrossing the ZPE25-10-1 x L545-93 F1 hybrid progeny and the donor line. The improvement of the grain yield of the elite hybrid should be carried out by backcrossing the B84 x L545-93 F1 progeny and the B84 parental inbred.en
dc.description.abstractCilj ovog rada bio je da se utvrdi koja od šest inbred linija kukuruza može da bude donor poželjnih dominantnih alela za prinos i njegove komponente prečnik klipa i broj zrna u redu. Ogled sa F1 hibridima i inbred linijama postavljen je 1998. godine po potpunom slučajnom blok sistemu na četiri lokacije (Zemun Polju, Srbobranu, Pančevu i Indiji) u četiri ponavljanja. Za izbor donora korišćen je modifikovani metod po Dudley-u (1987). Sve ispitivane inbred linije imale su pozitivne urednosti parametra mG, pri čemu je, na osnovu najveće vrednosti ovog parametra linija 1.545-93 odabrana kao donor poželjnih alela za popravku prinosa elitnog hibrida ZPE25-10-1 xB84 (0,95*). Pozitivne vrednosti parametra UG za ovu liniju utvrđene su i u slučaju prečnika klipa (0,26), kao i broja zrna u redu (2,54). Na osnovu relativne srodnosti linije L545-93 i roditelja elitnog hibrida ZPE25-10-1 X B84, zaključeno je da paralelna popravka prečnika klipa i broja zrna u redu može da se postigne povratnim ukrštanjem hibridnog potomstva ZPE25-10-1 X L545-93 sa linijom donorom. Popravka prinosa elitnog hibrida postići će se povratnim ukrštanjem F1 potomstva BS4 X L545-93 sa roditeljskom komponentom hibrida koji se popravlja B84.sr
