“…Fruit weight ranged from 47.53 ± 5.38g in American Trel to 253.96 ± 47.12g in "Lal Ambri". Similar variations in fruit weight ranging between 70g to 193.33g have been reported by Mratinic and Aksic (2011) for some local cultivars of apple in South Serbia. Pirlak et al (2003) also reported significant variations for fruit weight among some local apple cultivars ranging between 49.5g and 152.2g.…”

Kashmir Valley represents the richest repository of apple germplasm in India. A total of six cultivars based on commercial value namely Kullu Delicious, Gole Delicious, Lal Ambri, Raj Ambri, American Trel and Ambri Cross were studied using 38 morphological characters with main emphasis on fruit and leaf morphology. The fruit characteristics such as shape, size, flesh and skin colour, pH, TSS and fruit firmness are the most important market value traits of apple which together determine the quality of apple and its commercial success. All the six cultivars exhibited distinct characteristics with respect to these traits. Based on fruit quality traits, the cvs. Kullu Delicious, Lal Ambri and American Trel are highly acceptable in the Indian fruit market compared to other cultivars which have not attained commercial status as yet. All the six cultivars were found diploid with 2n=34. Chromosomal abnormalities such as univalents, precocious separation, non disjunction, disturbed anaphase and telophase, polysporads etc. were noticed during the male-meiotic analysis.

“…Globalization and standardization in the Serbian apple market have drastically reduced the numbers of autochthon cultivars and most of them have nearly disappeared; however, some of these cultivars, such as Petrovača, Budimka, Kolačara Pozna, and Kožara, have extraordinary quality, good pomological characteristics, and pest and disease resistance (Mratinić, 2005 ; Mratinić and Fotirić Akšić, 2011 , 2012 ).…”

Impact of Storage Temperature on Pollen Viability and Germinability of Four Serbian Autochthon Apple Cultivars

Globalization has drastically reduced the number of autochthon apple cultivars in the Serbian market and most of them have nearly disappeared; however, some of these cultivars, such as Petrovača, Budimka, Kolačara Pozna, and Kožara, have extraordinary quality, good pomological characteristics, and pest and disease resistance. The present study was conducted to develop a protocol for the storage of pollen for further use in the conservation and breeding of these cultivars. Viability and germination of the mature pollen were tested in vitro, at four storage temperatures (20, 4, −20, and −80°C), right after harvest or 1, 2, 3, 4, 5, and 6 months after storage. Differences in fresh pollen viability and germination between cultivars were statistically significant and ranged from 60 to 88% and 59 to 98%, respectively. Fresh pollen of cv. Budimka showed the highest viability and germination in comparison with other cultivars, especially cv. Kožara. Pollen viability and germination decreased over the storage period, and it was the lowest after 6 months of storage at room temperature in all tested cultivars. Storage at 4°C prolonged the pollen viability and germinability of 1–5 fold, depending on the cultivar and treatment duration; however, the pollen longevity of all cultivars was significantly extended when stored at −20 or −80°C. After 6 months, pollen of cv. Budimka stored at −20 and −80°C showed 14–15 fold higher germination rates in relation to pollen storage at room temperature for the same period. The results of the present study suggest that the pollen of these apple cultivars could be efficiently maintained at −20°C and could be further used for breeding purposes, e.g., for crossings between cultivars that flower at different times of the year.

“…Principal component analysis (PCA) has been used previously in many studies to evaluate germplasm of apple, and our results were in agreement with Pereira-Lorenzo et al (2003) findings regarding characterization of 89 morphological characters of 408 apple accessions using, the PCA revealed six main sources of variability in the following order: size of fruit, color of skin, acidity and sweetness. Mratinic and FotricAksic (2011) found that the first three components accounted for 65% of the total variable traits among 18 apple cultivars using 12 morphological characters.…”

This work was aimed to evaluate genetic diversity among five local and six introduced apple cultivars in the germplasm which located in the South of Syria based on 29 morphological characters of leaf and fruit. The analysis of variance showed significant differences at P < 0.05 for all measured parameters, however the mean values of Limb length and width, fruit weight, length, and width indicated to a wide range of diversity between local and introduced cultivars, that the introduced cultivars have mostly the highest mean value while the local cultivars have the lowest mean values, that clearly found in the local apple cultivar Ksairi (K) which revealed the lowest mean value of fruit weight (FW), fruit length (FL) and fruit diameter (FD) in the comparison with all studied cultivars. Likewise, principal component analysis (PCA) was used and the first 4 principal components accounted for 76.4% of the total variance, with eigen values 29.2%, 18.8%, 16.9% and 11.5% respectively.
