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.

本数据集包含7个作为母本的自交系（L）以及2个遗传基础多样、兼具耐热性的测验种作为父本（T）。通过L×T（7×2）交配设计获得14个杂交组合，即各母本自交系（f）与各父本测验种（m）以一对一方式完成杂交。为评估各杂交组合的杂种优势，本研究将所有亲本（含自交系与测验种）连同杂交组合一同种植于同一试验田，采用完全随机设计设置2次重复，对16个性状进行表型评价。
