Derakhshan, a new long eggplant variety, suitable for cultivation in warm and warm temperate regions of Iran

Given the performance and desirable quality characteristics of the fruit in the promising D7 line, the introduction of this line as a new variety of eggplant was very justified and will certainly be associated with a much higher economic income for the producer. In addition, the new version of Brilliant Eggplant is a very serious domestic competitor for foreign cultivars, which is completely in line with the goals of the Resistance Economic Program and is certainly a step towards preventing the outflow of foreign currency and helping domestic employment. Therefore, the promising Line D7 was introduced in 1397 as a new variety of bright eggplant.

In the project "Selection of Lines from Five Indigenous Masses of Eggplant in Iran", 5 indigenous masses of eggplant in the country were collected and subjected to a pure line selection correction program. Selected lines along with Varamin pen as a witness, for one year in three regions of Karaj, Varamin and Dezful under the project "Investigation of selected lines of native eggplants in advanced experiments" in the form of complete block statistics accidentally and were repeated in 3 replications. The performance stability of the genotypes was evaluated using the relative superiority coefficient method. The selected lines of advanced performance experiments in five regions of Karaj, Jiroft, Urmia, Dezful and Mazandaran were studied for two years. The experimental treatments included 4 advanced lines of sweet and semi-sweet eggplant and three witnesses (local Borazjan, Qasri Dezful and Black Beauty). Finally, an experiment was carried out in the field of farmers' farms in Dusari city, located in the south of Kerman province, with the cultivation of promising Line BJ30, D7, D1 and non-hybrid eggplants Results &

At the end of the first year of the project (2006) and due to quantitative and qualitative traits and with special emphasis on fruit traits, the top single plants were selected and at the end of their fruits were sown. In the second year of the project (2007) it was done as an agent, the top lines were selected, and the D7 line was selected as one of the selected lines with a difference of 10.3 tons per hectare with the mother control (Dezful Qasri Mass). At the end of the third year of the project, which was done in the form of a completely randomized block design and according to the average comparisons, the selected lines were selected and introduced for advanced experiments. As a result of these studies, the D7 line was selected with a yield of 39 tons per hectare and a difference of about 10 tons per hectare with the Varamin pen witness and having the highest yield among the selected lines from Dezful Palace. In advanced yield tests (2010) in Karaj, Varamin and Dezful regions, D7 line with a yield of 37.1 tons per hectare and with appropriate quality characteristics was selected as a top line. The results of compatibility and sustainability studies during the years 2011 to 2013 showed that this line with an average yield of 31.4 tons per hectare and the high sustainability. Line D7 was introduced as Derakhshan variety with its high yield, uniformity and good fruit quality.

The new Derakhshan eggplant (D7 line) was selected, evaluated and introduced by the method of pure line selection (single plant selection) during the years 2006-2018 from Qasri Dezful eggplant landrace. This line has always been selected as one of the top lines during all experiments such as Augment, preliminary, advanced and compatibility and stability Keywords: Quality, Uniformity, Yield stability.
