The development on inbred lines that produce high heterosis effect in crossing is an important step in a breeding programme. A study was conducted with sunflower to compare the effect of lines on the S3 and S4 generations in the formation of hybrids. Twenty four hydrids were obtained by crossing among three male sterile lines with twelve lines in S3 and S4 generations derived from one single improved population. A randomized complete block design, with four replications, was used in the evaluations. The statistical analysis was accomplished by following the hierarchical classification model with hybrids within generations and mother, and generations within mother. There were no significant differences between generations for all traits evaluated. These results suggest that it should be possible to choose the best lines already in S3 generation to continue the selfing generation process. |
