Özet

Direction and magnitude of mid-parent (MP) and high-parent (HP) heterosis were detected and estimated in 18 combinations, 180 F(1)s and 150 F(2)s for plant height (PH); spike length (SL); number of spike per plant (NS), number of spikelet per spike (NSP) and number of grain per spikelet (NG). For this, 9 females (7 commons Triticum aestivum (L.) Em. (Thell), P-5 = Akoz 867, P-7 = Kose 220/39, P-9 = Penjamo 62, P-10 = Sivas 111/33, P-11 = Surak 1593/51, P-12 = Sertak 52 and P-13 = Yektay 406 and 2 durums (Triticum durum Desf., P-1 = Kunduru 414/44 and P-4 = Kunduru 1149) and 4 semi wild males (P-2 = T. dicoccum., 2n = 28; P-3 = T. carthlicum; P-6 = T. vavilovi and P-8 = T. spelta., 2n = 42) were hybridized. The MP was varied between 33.1% (P(13)xP(8)) at the F-1 for the NG and 152.6% P-7 x P-8 at the F-2 for the NS; the HP was ranged between 71.2% (P(7)xP(8)) at the F-2 for the NG and 135.3% (P(7)xP(8)) at the F-1 for the NS. Heterosis effect was appeared mostly on the SL and PH; but fixed the highest on the NS and NSP in the each generation. The semi wilds were ordered as to be P-8> P-6> P-3> P-2. Statistically significant correlations were fixed between (MP-F-1) and traits; SL and PH traits were found have been impressed as to be more adventageous and stable.
