“…Our results are at par with the findings of other researchers. As reported by Kazankaya et al (2001) in Turkey, nut as well as kernel weight and kernel ratio of superior walnut genotypes were 11-12 g, 6-7 g and more than 45%, respectively. As per Ebrahimi et al (2011), the nut weight varied from 7.52 to 17.73 g, kernel weight from 4.00 to 9.83 g, and kernel percentage ratio from 38.78 to 67.05% amongst calculated genotypes.…”

The purpose of investigation was to assess the phytochemical and nutraceutical of walnut in leaf extracts through diverse quantitative and qualitative phytochemical tests followed by array of assays. The screening of 50 elite walnut genotypes which exhibited wide range of discrepancy in terms of phytochemicals as well as their anti-oxidant potential was done. Walnut genotypes displayed maximum divergence in quercetin content (2.86-5.78 mg/100 g) as represented by cluster analysis. The phenolic rich genotypes exhibiting total phenols (37.61-46.47 mg/g GAE) having higher DPPH potential (IP of 32.82-73.50) where as genotypes that accumulate flavonoids/flavanols (5.52-28.48 mg/g QE and 4.11-21.76 mg/g QE showed immense FRAP activity (418.92-1067.94 µM Fe/g FW). There was positive correlation between the phenolics content and anti-oxidant potential. The results showed oil content of 50.1-85.08% and kernel percentage 25.21-81.92% of all walnut genotypes. To evaluate the anti-proliferative potential of walnut genotypes, Trypan blue exclusion test, MTT assay and Griess assay was used. Each assay was repeated with different positive controls against a panel of human cancer cell lines viz THP-1, U2OS, IMR-32 and HBL-100 and then compared with the walnut extracts for their efficiency in anti-proliferative activity. The SPS 1 walnut extract at concentration of 500 µg/ml exhibited 10% cell viability and with 1000 µg/ml walnut extract there was consequent decline towards (6.25%) viability. The results indicated that walnut leaf constitutes an excellent source of effective natural antioxidants and chemo-preventive agents that can act as anti cancer agents.

“…The highest value for nut weight among our evaluated trees (15.2 g) was less than the corresponding data reported by Sen & Tekintas (1992) for Adilcevaz, Turkey (23.81 g); Atefi (1997) for Kamal Abad walnut collection orchard, Iran (20.9 g); Sharma & Sharma (1998) Sen & Tekintas (1992), Atefi (1997), Kazankaya et al (2001), Sharma & Sharma (2001), Yarilgac et al (2001), Acka & ozungun (2004), Zeneli et al (2004), and Aslantas (2006). In breeding programmes, genotypes with a kernel ratio higher than 48-50% are more desirable (Germain 1997;Korac et al 1997).…”

Fifty-eight mature Persian walnut (Juglans regia) seedlings growing at six sites in the mountainous regions of Taft, in central Iran, were evaluated to determine their morphological variation and to identify promising individuals. The traits investigated included phenological characteristics, such as budbreak and nut maturity time, and nut characteristics, such as nut and kernel weight, kernel ratio, and shell thickness. Yield efficiency and fruitbearing habit were also investigated. The average fruit characteristics: nut weight, kernel weight, kernel ratio, and shell thickness were in the range of 6.0-15.2 g, 2.6-9.1 g, 38.4-79.6%, and 0.4-1.4 mm, respectively. The promising genotypes were AA 33 thickness (0.67), kernel weight (0.75), and shell thickness (0.32); whereas a negative correlation was detected between shell thickness and kernel ratio (-0.34). The data correlation matrix was subjected to principal component analysis, a technique that reduced the dimensionality of the data set and revealed the dominating variables. Cluster analysis of the selected genotypes detected three cluster groups. However, no significant relationship was found between morphological diversity and site geography. The promising selected genotypes identified in central Iran will be further exploited by walnut breeding programmes for their tree and nut characteristics.

“…The pomological parameters of ripe fruits from different regions of Van Lake did not show significant (P>0.05) difference (except nut length). Pomologic properties of samples tested in this study showed good correlation with data previously reported for the walnut genotypes grown in Turkey (15,18).…”

In this study some physical and chemical properties of walnut genotypes grown in 5 different regions around Van Lake (Eastern Anatolia) harvested during ripening period have been determined. The average kernel ratios of ripe fruits from Adilcevaz, Ahlat, Edremit, Çatak and Hakkari found to be 45.7, 45.0, 42.2, 43.1 and 38.4%, respectively. The oil contents of fruits considerably increased during ripening and ranged between 65.7 and 70.7% in ripe walnuts. Linoleic acid was the most abundant fatty acid in walnut followed by oleic acid. The unsaturated fatty acids contents of samples remarkably increased during ripening. The tocopherol contents of walnuts considerably increased during ripening. The initial and final total tocopherol contents of samples varied between 8.3-18.5 and 121.9-135.4 mg/100 g oil, respectively. Potassium was the most abundant mineral in ripe walnuts followed by Mg and Ca. The results showed that these genotypes were promising walnut types and selection researches should be carrying out to produce standard walnut types from this genotypes.
