In this study, morphological characteristics as well as ten of Simple Sequence Repeat (SSRs) loci were used to analyze the genetic diversity and relationships among 12 natural populations of Persian walnut (Juglans regia L.) in northern and western regions of Iran. The results showed that there was a high level of genetic diversity among the walnuts, both in terms of their SSRs loci as well as ...

A study to mea~ure the effect of walnut scale infestation on English walnut qualityand yield has shown no differences in yield and no consistentdifferencein kernel quality between infested and non-infested trees for the four years ~f the study. Yield and quality of English walnut are not overly sensitive to walnut scale infestation and some degree of infestation can be tolerated with no measura...

identification and evaluation of indigenous genotypes of fruit trees are matter of consideration at the first step of the breeding programs. in order to study genetic diversity and to identify promising genotypes, 14 different genotypes of walnut in minoodasht region in golestan province (north of iran) were evaluated. traits such as nut shape, kernel color, ease of removal of kernel halves, ke...

Late spring frost is one of the most important factors causing loss of production of the Persian walnut (Juglans regia L.). Therefore, the selection of spring frost tolerant genotypes has been among the most important priorities in the breeding programs during the recent years in Horticultural Science Research Institute, Karaj-Iran.  After the spring frost in 2010, five superior genotypes (B10,...

this study was carried out to investigate the important characteristics in some cultivars/genotypes of persianwalnut (juglans regia l.), black walnut (j. nigra l.), and walnut inter-specific hybrids: paradox (j. hindsii × j.regia) and royal (j. hindsii × j. nigra) in kamalshahr research station in karaj in 2011-2012. in the study,vegetative vigor was evaluated based on trunk cross-sectional are...

in this research the quality of walnut kernels under impact loading were studied. due to unavailability of specific varieties of walnut in iran, the tests were carried out on the available genotypes. three different genotypes from walnut orchards of azarshar region were selected and were collected in 2009. a drop test device was designed and constructed to perform the experiments. the impact te...

Walnut (Juglans regia L.) is a well-known member of the Juglandaceae family and its kernel is widely consumed around the world for both unique nutritional characteristics and health-related benefits. Even though several studies investigated the composition and biological activities of different parts of the walnut tree, the internal septum of the walnut kernel is less evaluated. In the...

The black walnut (Juglans nigra L.) is an underutilized fruit in the mid-hills of Nepal. However, the physico-chemical properties of Nepalese black walnut are almost unavailable in the literature. Four walnut growing districts namely Baitadi, Dadeldhura, Jumla and East Rukum selected and the black walnut collected at commercial maturity from the local markets. The physical properties w...

OBJECTIVE Walnut (Juglans Regia) is a domestic fruit of Iran. Walnut kernel (WK) has many beneficial constituents such as unsaturated fatty acids, antioxidants, and vitamin E. Scientific studies have shown that fatty acids and vitamin E can modulate learning and memory processes. The aim of the present work was to study effects of walnut consumption by mothers during pregnancy and lactation on ...
