This study was conducted with controlled crosses to understand the genetic potential of determinate growth habit in field environment during the 2008 to 2011 growing periods. Muganli-57 (...) with indeterminate growth habit was crossed to ACS 337 (...), which has determinate growth habit. In the F1 generation, all the plants were indeterminate. In F... population, a 3:1 segregation ratio indicating determinate character was controlled by a single recessive gene. To assess the cross effect on indeterminate and determinate sibs in F... generation, data for both phenotypes were separately generated. Heritability estimates in narrow sense were low for stem length to the first capsule, plant height, number of capsules per plant and seed yield in determinates. This result showed that additive gene effect played an important role for both determinate and indeterminate types and these positive shifts continued in F... generation compared to parental lines.
