Estimation of Heterosis and Heterobeltiosis in an 8x8 Diallel Cross Bread Wheat F3 Population

Hybrid vigor which often observed in F1 plants is also important in F3 generations. Eight bread wheat (Triticum aestivum L.) genotypes (Midas, As-14, Rumeli, Esperia, Gl-14, Krasunia odes’ka, Masaccio and Lucilla) from both different origins and agricultural traits were crossed in a half diallel cross and evaluated for heterosis and heterobeltiosis in F3 populations for some yield components. The experiment was conducted in a randomized complete blocks design with four replications in Lüleburgaz/K？rklareli under farmer conditions in 2016-2017 cropping year. Positive heterosis and heterobeltiosis values were observed for all investigated traits in almost all crosses. The values of heterosis and heterobeltiosis for spike length, spikelet number per spike, grain number per spike, grain weight per spike and grain yield per plant ranked between 28.76 and 22.73%; 10.75 and 5.51%; 25.46 and 16.52%; 46.66 and 31.61%; 46.92 and 32.20%, respectively
