Drought is one of the main dangers for optimum production of wheat. Achieving optimal results in breeding programs require to make informed choices of parents based on general and specific combining ability.In order to study the genetic characteristics, general and specific combining abilities and gene actions under drought stress conditions, a half diallel cross including 9 varieties of wheat ...
