| Abstract | ||||
| The present investigation aimed to estimate general combining ability (GCA) variances and their effects for different characters in tomato (Solanum lycopersicum L.) under heat stress at Al- Kharj, Saudi Arabia conditions. Line × Tester analysis including three lines and two testers illustrated the preponderance SCA over GCA for all the studied characters in this investigation. Based on the obtained data both Supermarmande and Nagcarlang genotypes were good combiners for fruit set, yield plant characters while Supermarmand and Super Strain B genotypes were a good combiner for fruit weight. In addition to Supermarmand genotype was a good combiner for characters i.e., plant height, fruit diameter, number of locules, TSS and number of branches/plant. While, Peto86 genotype show that a good combiner for Flash Thickness trait. The crosses (Nagcarlang x Castle Rock), (Superstrian B x Peto86) and (Superstrian B x Castle Rock) was marked as the most promising crosses for yield per plant character under heat stress conditions. | ||||
