Malatya is considered to be a center of dried apricot production. The production is dependent on only a few cultivars like 'Hacihaliloǧlu' and 'Kabaaşi'. To diversify the production patterns, fresh consumption of apricots grown in the region is being encouraged. For this purpose, extending the harvesting period utilizing early and late table cultivars is crucial. A breeding study aimed to develop new late-ripening apricot cultivars was initiated at Inonu University. A total of 2250 hybrid trees was planted to experimental plots from 24 combinations. More than 1200 hybrid trees developed fruits in two consecutive seasons and the fruits were subjected to pomological analyses. A great deal of variation was observed for maturity date which was controlled by several factors. Several promising hybrids were selected for further investigations. The maturity period ranged 148-172 days for these selections while they produced fruits of 23.2-45.4 g weight and 18.0-22.1% soluble solids.

Turkey has important mulberry genetic resources. In contrast to the other mulberry producing countries, in Turkey mulberry tree is used only for fruit production not for sericulture purposes. Some selected morphological fruit characteristics such as seed formation, fruit weight, SSC (Soluble solid content), titratable acidity, juice yield and pH of 34 selected mulberry genotypes found together in an ex-situ collection parcel in Malatya Fruit Research Institute in Turkey were investigated. The collection parcel has been established in 1996 year with 3×5 m row spacing. The morphological fruit characteristics are represented of 3 years average data (2006-2008). The results showed that there were big differences among genotypes in terms of most of the fruit characteristics. Fruit weight varied from 0.66 (Istanbul dutu 2) to 3.07 (Gumushaci beyaz); SSC varied from 17.33% (Erzincan karadut 16) to 30.67% (Lokum dut); titratable acidity varied from 0.06% (Angut 9) to 1.62% (Gumushaci karadut 8) and pH varied from 2.19 (Kemaliye karadut 9) to 5.86 (Mersin mor dut), respectively.

This study was conducted in Malatya, between 1999 and 2003, and the region's most important dried apricot variety, Hacihaliloglu was used as material. In the study, the effect of 5 different combined or alone pruning treatments on the growth, fruit quality and yield characteristics were determined in comparison with non-pruned trees. Pruning treatments in different periods did not statistically affect phenological features and fruit dimensions but strongly affected total soluble solid and fruit firmness of Hacihaliloglu apricot cultivar. The highest average yield considering trunk cross-sectional area was obtained as 0.34 kg·cm -2 from pre-harvest summer pruning treatment and the highest share of flower bud was observed as 68.29% in pre-harvest summer+winter pruning treatment. Pruning applications significantly affected both shoot diameter and length. The highest shoot diameter and length were obtained from pre-harvest summer+winter pruning application as 8.52 mm and 77.84 cm, respectively. The highest leaf area was determined as 39.43 cm 2 in post harvest pruning treatment.

A study was aimed to detect the aroma profile of 20 apricot cultivars, i.e., 'Turfanda Eski Malatya', 'Karacabey', 'Paviot', 'Zerdali No.1', 'Aprikoz', 'Soganci', 'Hasanbey', 'Roxana', 'Royal', 'Sekerpare', 'Cataloglu', 'Kabaasi', 'Stark Early Orange', 'Sakit-3', 'Hacihaliloglu', 'Iri Bitirgen', 'Casna Drenova', 'Cologlu', 'Ordubat' and 'Imrahor' which are grown at the Fruit Research Institute in Malatya province of Turkey. Aroma compounds were identified using gas chromatography (GC) with mass spectrometry (MS). Extraction was done automatically using headspace apparatus of GC/MS. Aroma composition of apricot genotypes varied according to genotype. Among the detected aroma compounds, 12 alcohols, 8 aldehydes, 4 esters, 3 terpenes, 2 lactones, 2 ketones, 2 acids and 3 other compounds were identified and γ-decalactone was detected as the major compound in 'Hacihaliloǧlu' which is our local and leading genotype.

This study was aimed at assessing the quality characteristics of 21 apricot genotypes such as Turfanda Eski Malatya, Karacabey, Paviot, Zerdali No.1, Aprikoz, Soǧanci, Hasanbey, Levent, Royal, Şekerpare, Çataloǧlu, Kabaaşi, Stark Early Orange, Sakit-3, Sam, Hacihaliloǧlu, Iri Bitirgen, Casna Drenova, Çöloǧlu, Ordubat, Imrahor that are grown in Malatya provinces of Turkey. Main soluble sugars of experimental varieties were separated, identified and quantified using high-performance liquid chromatography with refractive index detection. According to the results, sugar composition of apricot genotypes was different from one genotype to another. Sucrose, glucose, and fructose were determined as the major sugars in all apricot varieties and our local genotypes were detected to have higher concentration in terms of identified sugars.

Twelve-year-old apricot trees from the 'Hacihaliloglu' apricot cultivar were pruned in a series of five treatments. In all treatments, one-third of annual shoots (33.3%) were removed between 1999 and 2003. The chlorophyll a, chlorophyll b, total chlorophyll and carotenoid contents in leaves were determined. The starch, total sugar, reducing sugar and sucrose contents in shoots were also determined. In addition, seasonal variation of carbohydrates was studied. The treatments did not affect the carotenoid content of leaves, but they statistically affected the total chlorophyll content. The highest total chlorophyll content in leaves was 5.27 mg/g, and it was found in the post-harvest summer/winter pruning treatment. The highest average total sugar content (6.25%) was observed in the post-harvest summer pruning treatment, while the lowest (2.56%) was found in the post-harvest summer/winter and control treatments. The highest starch content (8.18%) was found in October from the post-harvest summer/winter treatment, whereas the lowest value (3.59%) was obtained in March from the winter pruning treatment. Summer pruning treatments promoted an accumulation of carbohydrates.

The study was carried out between 2004 and 2005 years in Malatya Fruit Research Institute. The fumigation of 1600, 1800 or 2000 g SO2 were applied for 6, 8, 10, 12 and 24 hr after harvest on dried 'Hacihaliloglu' apricot fruits. The loss of SO2, product moisture (%), product temperature, acidity (%), pH and the colour of the apricot fruits were determined after the drying processes on the wooden trays following the SO2 fumigation and during storage periods. The results showed that the average level of the SO2 in the dried apricots was found as 2000 ppm after fumigation as requirement of European regulations. Dried apricot fruits had 2174 ppm of SO2 in 2004 and 1586 ppm of SO2 in 2005 at the beginning of storage and these amounts were decreased to 1284 and 1091 ppm at the end of 12 months of storage in normal atmospheric conditions. The loss of SO2 amount in dried apricots was found to be directly proportional with the initial quantity of SO2. When the level of SO2 in dried apricots was decreased to 1500 ppm, the quality of the product was also decreased and the colour of dried apricots are darkened. As a result of this study, can be recommended that the dried apricots including 2000 ppm SO2 should be marketed after 6 months of storage.

The S-genotypes of a set of Turkish and Hungarian apricot (Prunus armeniaca L.) cultivars were determined by polymerase chain reaction (PCR) amplification of their S-RNase intron regions. In addition, the S-genotyping method was extended to the SFB gene to detect the non-functional SC-haplotype and hence reliably identify self-compatible apricot cultivars. We determined the complete S-genotype of 51 cultivars and the partial S-genotype of four cultivars. A total of 32 different S-genotypes were assigned to the 51 cultivars, and many of them (28) were classified into newly established cross-incompatibility groups III through XIV. Another 12 cultivars demonstrated unique incompatible genotypes and seven self-compatible cultivars were identified in the examined accessions. The fact that Turkish and Hungarian apricot cultivars carry 12 and five S-alleles, respectively, and all five alleles detected in Hungarian cultivars were also present in Turkish apricots furnished molecular evidence supporting the long-suspected historical connection between Hungarian and Turkish apricots. The connection between these two gene pools appeared to be relatively recent and associated with historical events dating back 300 years. Our results confirm that Turkish germplasm contributed considerably to the development of several desirable Hungarian apricot cultivars. Results suggest that the mutation rendering the SC-haplotype non-functional might have occurred somewhere east of central Turkey.
