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...

The flavour and nutritional values of pears are appreciated by consumers worldwide, who, however, demand specific fruit quality, that is, attractive appearance, firmness and flavour, and health safety as well as long-term shelf life and storability. Pear cultivars differ in terms of the above-mentioned traits; therefore, we undertook investigations to demonstrate the differences in structure of...

The purpose of this study was to characterize olive core collection with amplified fragment length polymorphism (AFLP) markers and fruit traits and to determine AFLP markers significantly associated with these fruit characters in olive. A total of 168 polymorphic AFLP markers generated by five primer combinations and nine fruit traits were used to characterize relationships between 18 olive cul...

Apple cultivars exhibit significant diversity in fruit quality traits, creating distinct consumption scenarios. This study aimed to assess the physicochemical parameters and sensory attributes differences among fifteen apple identify characteristic qualities suitable for various processed products using chemometric analysis. Relatively large were registered between deflection, peel color, titra...

iran, with a long history of apricot cultivation is one of the most important apricot producers in the world. centuries of sexual reproduction via seed, have developed many divergent variations of apricots in iran. however, unfortunately there is no comprehensive report available concerning its diversity and genetic make-up. in this study, 39 iranian apricot cultivars as well as accessions, nat...

in order to study the effects of ga3and cacl2 treatments in resolve the problems of sweet pepper culture in ilam region (including small size fruits with sunscald and blossom end rot disorders), this study was carried out in ilam university in 2012. for that, ga3 (50 mg/l) and cacl2 (0.5%) treatments were sprayed at two (fruit set and 15 days thereafter) and three (fruit set, 10 and 20 days the...

extended abstractbackground and objectives: loquats have formed different ecological types during their cultivation and adaptation in different parts of the world. the first step in the breeding operation is the identifying of the spread center accompanied the studying of the variation between genotypes. in this research, 20 loquat genotypes were evaluated using fruit morphological markers to i...

UV light provoked stress can evoke antioxidant defence system and consequently induces the synthesis of several phytochemical compounds. Th e aim of the present study was to investigate the infl uence of UV-B light irradiation on surface colour and synthesis of some bioactive compounds in apples skin of cultivars ‘Elstar’ and ‘Jonagold’. Half of each apple was shaded with aluminium foil to comp...
