The present study was conducted to evaluate the factors (e.g. cultivar (V), wild species line (L), year (Y) and their interaction) affecting the production of a BC
1F
1 population (cultivar × F
1(cultivar × ‘
peruvianum-complex’)), a breeding strategy for using many cultivars as pistillate parents for the production of a BC
1F
1 population and for the segregation of some characteristics such as sweet aroma of leaf, morphological traits and self-incompatibility in the BC
1F
1 population. Ovule selection and culture method was used for the production of progenies. The interaction between the cultivar and the wild species line (V × L) was found to be significant. Differences in the number of GOFs (Germinated Ovules per Fruit) among 19 tomato cultivars crossed with F
1 (cultivar ×
L. peruvianum LA1554) were significant. Differences in the number of GOFs among wild species lines (as F
1 pollen parents) were also significant and much more pronounced than those of the cultivars. Significant variation was observed within-year and affected the interaction (V × Y) which was variable. The present study suggests that the probability of obtaining a stable, consistent average number of GOFs is high for the production of a BC
1F
1 population if many cultivars are used at a time as seed parents. The segregation of some characteristics in the BC
1F
1 population was evaluated. Most of the morphological traits resembled those of the wild species parents. Thirty six percent of the BC
1F
1 population inherited self-compatibility from the L. esculentum parent. A sensory panel composed of 8 members evaluated the leaf aroma of 100 BC
1F
1 plants (19 cultivars × F
1 derivedfrom LA1554) and two BC
1F
1 plants were found to have the same sweet aroma as the F
1 (pollen parent). In the present study a large BC
1F
1 population with an expected number of plants was obtained. Sensory attributes of some BC
1F
1 plants suggested that the expected quantitative trait had successfully been introduced into the BC
1F
1 population.
