This work was carried out in the clay soil of the Experimental Farm of Assiut University, Assiut during the summer season of five years from 1998 to 2002. The purpose of this investigation was to study 1) the mode of inheritance and different gene actions that control some vegetative, reproductive and yield characteristics in okra, 2) the effect of different irrigation regimes (irrigation intervals) on growth and yield of some selections F3 generations, with the aim of getting lines having better performance yield and good quality fruits under water stress conditions.
Two main experiment were included in this work:
Experiment I: Genetic studies of some horticultural traits:
Five okra genotype [Velvet Round cv. (P1); T13 TVRNAB cv. (P2); Sudaneez type (P3); Ashkor, Fakous (P4) and El-Badary (P5) subjected to diallel cross to obtain the possible 10 F1’s without reciprocal. In 2000 season the 10 F1’s with the five parental materials were grown in a complete randomized block design with three replications. Twelve traits were studied in this work (vegetative, reproductive, yield and its components and fruit quality characters).
The results of this experiment could be summarized as follows:
- Significant differences were found among the studied genotypes (5 parents and 10 F1 ‘s) regarding most vegetative, reproductive; yield and its components and fruit quality characters.
- Regarding combining ability i.e. GCA and SCA, for the studied parents. It is clear that P3 and P4 showed the highest estimates for
