| Abstract | ||
| The experiment was conducted in a farm at Al- Haddama area/Safwan district/ Al Zubair region/ Basrah province, during seasons of 2007/2008 and 2008/2009 to test three hybrid cultivars of summer squash (Kriti F1, Amjad F1 and Arti F1). These cultivars were compared with the local cv. Mulla Ahmed in characteristics of vegetative growth (plant height, spreading area, leaf and peduncle area, fresh and dry weights of the leaf, total chlorophyll) and yield (days from cultivation to Horticultural maturation, number of fruits/plant, mean weight of the fruit and its length, yield per plant, total productivity). In addition to the qualitative characteristics of leaves and fruits which included fat, protein, carbohydrates, nitrogen, phosphorous, potassium and refractive index of oil in seeds Randomized Complete Block Design (RCBD) with three replications was used . Means were compared through least modified differences test (L.S.D.) at aprobability levelof 0.05. Results showed a variation in the response of the cultivated cvs. due to the environmental surroundings, where Kriti F1 superiority in fresh and dry weight of leaves in the first season, the content of nitrogen, phosphor, potassium and protein percentage in leaves and fruits in the second season. In addition, the number of fruits, yield per plant, total productivity and refractive index of oil in seeds for both seasons. Amjad cv. provided the highest content of carbohydrates in leaves and highest number of fruits per plant for the first season, and highest yield per plant and total productivity for the second season, and superiority in the leaf area and fruit contents of carbohydrates for both seasons. Results also showed that the superiority of Arti F1 cv. in fresh and dry weights of leaves and the mean weight of fruit for the second season, height of plant and spreading area for both seasons. Mulla Ahmed cv. surpassed in leaves content of total chlorophyll for both seasons, and an increase in carbohydrate content in the first season, phosphor us in second season and fruits content of carbohydrates in the same season. The three cv. recorded an increase in the leaves and fruits content of potassium for both seasons as compared to the cv. Mulla Ahmed. | ||
