Dissertation note: Thesis (Ph.D.) - Cairo University - Faculty of Agriculture - Department of Agronomy Summary: Selection index was constructed to help selection for several important traits simultaneously. Judicious use of conventional and restricted selection indices is of a great importance to the breeder because selection focuses on breeding value, the portion of genetic superiority transmitted to progeny. Selection of F₆ line (s) that combine high seed yield with one or more desired agronomic or seed yield component trait in a new cultivar was practiced via 12 conventional and two restricted selection indices. These lines were evaluated in the next generation (F₇) in an evaluation experiment. The two experiments were grown in the Agricultural Production and Research Station of National Research Center, El Nubaria district, Egypt, in 2011 and 2012 seasons, respectively. The results showed significant genetic variances among lines for all studied traits expect days to maturity in F₆ and fruiting zone length in F₇. Mean performance of F₆ and F₇ lines were higher than the check cultivar for number of branches plant⁻¹, number of capsules plant⁻¹, seed yield plant-1, oil % and seed yield plant⁻¹, Height to 1st capsule, branches plant⁻¹ and seed yield plot⁻¹ showed higher values of PCV and GCV, also reported from high to moderate heritability.
