دراسة اهم الصفات الاقتصادية و الانتاجية للطرز المحلية من القرع العسلي Cucurbita moschata ,Duch

The local types of Pumpkin is considered as a rich source of variation and can be used as a main selection material in breeding programs to improve the characteristics of this crop. In this research, nine local types of Pumpkin (Cucurbita moschata ,Duch) have been studied from 2001 to 2003. The study included plant phonological phases, economical characteristics, and the most important quantitative characteristics relating to fruit yield to evaluate the characteristics of every type and identify the economical types to use in the breeding programs. The study of results showed genetic variation between the groups for some important economic characteristic as (stem long. No of nodes till the first female flower, sexual ratio ♀/♂, fruit average weight, the average weight of 100 seeds). The results appeared also the positive correlation between the productivity and some important economic characteristics, such as (stem long, nodes number, sexual ratio ♀/♂, the average weight of fruit, the number of fruits per plant). this means that we can consider the weight fruit character, as selection index for productivity character followed by the steam long characteristics, number of fruits per plant.
