Data set for estimating combining abilities for yield and quality attributes in summer tomato using line by tester analysis in Bangladesh

The dataset includes seven inbred lines as female parents (L) and two testers as male parents (T) with diverse genetic bases and heat tolerance qualities. Fourteen cross combinations were produced through an L×T (7 × 2) mating design, involving hybridization between lines (f) and testers (m) in a one-to-one fashion. To assess the heterosis of the crosses, all parents (both lines and testers) were included along with the crosses and evaluated in the same experimental field for 16 traits using a completely randomized design with two replications.
