| چکیده | ||
| This study aimed to evaluate the general and specific combining abilities and the gene action mechanisms for some traits of cucumber. The study was conducted using an incomplete diallel cross in a completely randomized design with three replications during the 2022-2023 growing season at the Faculty of Agriculture, University of Guilan. The results indicated significant differences in all traits except for fruit width and plant length. The mean squares for general and specific combining abilities were significant for traits such as the number of pistillate flowers, the number of staminate flowers up to the 15th node, the number of final nodes, fruit weight, number of fruits, and yield per plant, indicating that both additive and non-additive gene actions were involved in the genetic expression of these traits. However, the mean square for specific combining ability was not significant for ovary length, suggesting no significant difference among hybrids in terms of specific combining ability for controlling this trait. Additionally, based on the results, the highest significant positive and negative general combining abilities at the 1% probability level for yield per plant were associated with line 3 (0.21) and line 2 (-0.22), respectively, indicating an increase in this trait in line 3 and a decrease in line 2. Therefore, line 3 could be utilized in breeding programs to enhance yield. The findings of this research demonstrated that additive variance played a more significant role in controlling the traits than non-additive variance, and the use of selected recombinant inbred lines is recommended. | ||
