“…Many countries have similar germplasm collections for other minor fruits such as ber, pomegranate, litchi, jaman, etc., consisting of most of the possible varieties of these fruits in these countries. Similarly, fig collections have been reported from different countries such as Tunisia [32,33], Turkey [12,29,56], Morocco [8,57,58], Spain [35,59], Lebanon [60], Iran [4], Kashmir [23,38] and Jordan [36]. These studies have shown that the diversity of morphological and pomological characters could be useful for an efficient marker system to distinguish between different fig genotypes.…”

Wild Himalayan figs (Ficus palmata Forsk.), native to East Asia and the Himalayan region, are closely related to the well-known cultivated fig (Ficus carica L.), which is grown mainly in the Mediterranean region. The Pakistani state of Azad Jammu and Kashmir has a rich variety of figs. However, no comprehensive study has been carried out to utilise the diversity of these wild figs for possible use in sustainable fruit production. Therefore, the present study was designed to assess the variability of 35 wild fig accessions using quantitative and qualitative traits. Descriptive statistics were used to measure quantitative characteristics, while the coefficient of variance (CV %) was analysed using SAS® version 9.1. A principal component analysis (PCA) and multivariate analysis were performed using R Studio (v1.1.4). Pearson correlation coefficients between characteristics were obtained using SPSS software. The studied accessions showed high variability and the coefficient of variation (CV) ranged from 4.46–14.81%. Days to maturity varied from 71 to 86, leaf area from 38.55 to 90.06 cm2. The fruit length, fruit diameter and fruit weight ranged from 11.25 to 29.85 mm, 11.85 to 27.49 mm and 2.65 to 9.66 g, respectively. The photosynthetic activity and total chlorophyll content also varied from 7.94 to 10.22 μmol CO2 m−2s−1 and 37.11 to 46.48 μgml−1. In most of the fig accessions studied, apical dominance was found to be ‘absent’ while fruit shape was observed to be ‘globular’. A strong correlation was observed between all the studied characteristics. In the PCA analysis, all 35 fig accessions were distributed in four quadrants and showed a great diversity. This could be a valuable gene pool for future breeding studies and provide improved quality varieties. Wild Himalayan figs from the wild are well adapted to local pedoclimatic conditions and, combined with easy propagation and production can contribute to the local economy and have a significant impact on the socio-economic and ecological balance. The results of this study show high variability in some of the studied traits of 35 accessions from different parts of Northeast Pakistan, indicating their good potential for further enhancement and utilisation in sustainable agricultural production.

“…The collection of multiple data for the characterization of caprificus genetic resources in field conditions and the laboratory environment continues with similar to approaches and studies of other countries/researchers [4,5,6,7,11,12,13,14,15,16,19].…”

“…Pollen was collected from a total of 24 individuals, including 20 caprifig genotypes sampled from Adana, Hatay, Kahramanmaraş, Mersin, and Osmaniye provinces in the Eastern Mediterranean Region and 4 standard caprifig varieties from Aydın in the Aegean Region of Türkiye to determine the pollen characteristics. Polar length, equatorial diameter, colpus width, pollen shape, porate number, porate width, exine thickness, and abnormal pollen ratio were determined as the most important distinguishing criteria [6].…”

Wild caprifig trees, varying rich genetic diversity in Turkey, constitute one of the valuable genetic resources. Caprifigs are important to protect the genetic resources to transfer the futureare used as pollinators. Fig Research Institute Directorate (Aydın/ Türkiye) is the institution primarily responsible for the protection of caprifig genetic resources. It has aimed to protect the caprifig cultivars and genotypes collected by survey and selection studies carried out in the fig growing regions of Türkiye, enrich the collection with new cultivars and genotypes, characterize them and provide genetic diversity for further breeding studies. The creation of the caprifig genetic resources plot began in the 1960s. As of 2022, the number of varieties and genotypes in caprifig genetic resources is 70. In this research; The project work has been evaluated in general terms, and the scientific studies on genetic diversity so far have been given in detail. Average fruit weight of Profichi fruits was determined between 7.71 - 49.40g. The birth of the fruits have occured between 05 March and 08 April.

“…Similarly, Franchi et al [55] reported that plants such as grasses, spinach, walnut and pumpkin have this kind of pollen, and because of its water content and the lack of mechanisms to prevent the formation of ice crystals, it is difficult to store them at low temperatures. There have been no published reports that classify fig pollen as recalcitrant; however, if fig pollen is classified as resistant pollen due to pollen size [56], the obtained lower viability and germination rate at 0 • C may be explained. In contrast, previous research on several other fruit varieties (e.g., apple, almond, cherry, hazel) revealed that pollen germinability may be optimally maintained in storage at temperatures lower than 4 • C [18,21,22,45].…”

Caprification is the process of hanging caprifig fruits on edible fig trees to transfer the pollen inside the caprifig to the edible fig via the wasp (Blastophaga psenes) living in the caprifig. It needs to be repeated several times for the proper fruit set of edible figs. The present study was conducted to determine the change in the number of Blastophaga psenes, the duration of Blastophaga’s exit, and pollen viability in case the caprifigs to be used in the caprification process are stored until use. The number of Blastophaga and in vitro pollen viability were tested at day 0 (harvest day) and after 4, 8, 12, 16 and 20 days of storage at three different temperatures (0, 4, and 8 °C). Afterwards, the effect of pollination frequency on the edible fig fruit set and quality was determined by using Blastophaga psenes as a vector in the pollination of stored caprifig fruits, pollinating five times with 4-day intervals and three times with 8-day intervals. Approximately a 50% reduction in the number of B. psenes was detected after 4 (180.22), 12 (174.11) and 16 (192.66) days of caprifigs storage at 0, 4, and 8 °C, respectively. The pollen germination percentage of the caprifigs increased with storage and was higher in those stored at 8 °C (43.96%) and 4 °C (41.70%). The highest fruit set was obtained when the caprifigs stored at 4 °C (76.41%) and 8 °C (71.38%) five times with 4-day intervals were used for pollination. The pollination practice repeated five times with 4-day intervals resulted in a lower proportion of extra-large fruits with a weight of >100 g, a higher proportion of fruits with no or slight ostiole damage and early ripening of fruits. These results suggest that B. psenes and pollen viability can be preserved by storing caprifigs at 4 or 8 °C and that fruit set and fruit characteristics would be positively affected with the use of stored caprifigs in the pollination practice repeated five times with 4-day intervals.
