| Abstract | ||
| In the spring season (2014) was six lines of sunflower input (C, Q, F, I, E and A) In full diallel cross, to get the 15 singles hybrid and 15 reciprocal hybrid. Planted genotypes (parents and singles hybrids and reciprocal) in experiment compared to using randomized complete block design (RCBD) with three replicates in a farmers' fields in township of Kifl located south - Babylon during the autumn season (2014( . And taking the data for the traits of leaf area, diameter disk, number of seeds in the disk , 100 seed weight, yield seeds per plant, ratio of oil in the seed and yield the oil in the plant and to study the heterosis and measured on the basis of deviation hybrids single and reciprocal for the best of the parents to estimate the heterosis of the traits studied. The median genotypes squares (parents + single hybrids and reciprocal) the high significant when probability 1% of all traits. Discriminate hybrid cross (Q × I) and (I ×A) and reciprocal (A ×E) , (I × Q) and (A × Q) show heterosis of the high significant and desirable for most of the measured traits on the basis of the F1 for the best parents deviation. And The results showed the importance of cytoplasmical Effect study in all the traits of sunflower. | ||
