Abstract

In order to heritability estimate and identify the number of controlling gene of some traits in crossing Omid bread wheat and La/b tritipyrum primary line, parent seeds and F₁, F₂ and F₃ generations obtained from crossing Omid wheat variety and La/b tritipyrum primary line were planted in farm condition. The traits such as tiller number, high plant, stem length, leaf number, node number, inter node distance, flag leaf length, flag leaf width, ear number, number of spikelet per spike, ear length, own length, spike diameter, leaves length of non flag leaf were measured and noted. The obtained results from variance analysis showed that generations squares average were segregation for all traits, therefore generations mean analysis for all mentioned traits were performed. The results obtained show that dominant variance played most roles in controlling traits inheritance. Also, averages of broad sense heritability were estimated from 0.52 to 0.93. The number of controlling gene in reviewed traits were estimated from 1 to 4.
