Evaluation of yield, quality and quantity characteristics of Strawberry Cultivar under greenhouse conditions in Jiroft and Kahnoj rejoin

Jiroft with unique climate is one of the most important and suitable regions for production of greenhouse crops in Iran. Strawberries are a viable crop in most greenhouse of the Jiroft. Selection of appropriate varieties is important besides determent yields and quality. In order to this study, 10 cultivars including Paros, Camarosa, Queen Elisa, Pajaro, Selva, Diamante, Gaviota, Merak, Missionary and Kordestan were grown to evaluate their yield and quality under greenhouse in 2007-2008 years. The experiment was in a Randomized Complete Block Design with three replications. The strawberries were grown on double row of raised beds covered with a black plastic according to standard recommendations for strawberry production in Jiroft in early autumn. During the production in the greenhouse, the parameters such as total yield, titratable acidity quantity, soluble solid content, vitamin C and diameter, weight average of fruit and a viable runner product were measured. According to total yield of two years, there were significant differences between cultivars. There were also significant differences in average fruit weight among cultivars, the highest average fruit weight under conventional and greenhouse followed by Queen Elisa and Paros cultivars. Paros, Pajaro, Queen Elisa, Selva, Missionary and Kordestan cultivars had the highest TSS content under conventional system. Titrtable acidity of fruit was not strongly affected by cultivars management and it was lower under growing conditions. Paros cultivar produced the highest total and marketable yields followed by Camarosa, Pajaro and Selva cultivars. Missionary and Kordestan produced similar amounts of yield fruit. There was no difference in soluble solids which indicates that yield differences did not come at the expense of soluble solids, which is important for processing fruit. Under this condition, TSS content of cultivars showed variability, namely the values were lower in the second year when compared to the first year. This might be resulted from susceptibility of these cultivars to nutritional differences in the soil., differences between vitamin C to this trait of each cultivar was not significant. TSS content is a cultivar-specific character. While some cultivars had higher TSS, the others had the lower TSS under the same growing conditions. Pajaro Cultivar was produced highest growing runners during two years. Generally results showed that Paros, Camarosa, Queen Elisa, Pajaro and Selva cultivars are recommended for greenhouse in the Jiroft and similar regions.
