Nectarines play a key role in peach industry; the fuzzless skin has implications for consumer acceptance. The peach/nectarine (G/g) trait was described as monogenic and previously mapped on chromosome 5. Here, the position of the G locus was delimited within a 1.1 cM interval (635 kb) based on linkage analysis of an F2 progeny from the cross 'Contender' (C, peach) x 'Ambra' (A, nectarine). Care...

Populations of Brachycaudus schwartzi (Börner) were found on peach and nectarine (Prunus persica Siebold & Zuccarini) trees in Parlier, CA, in summer 2000. To determine if this aphid could be a pest of P. persica, a nine-variety host range test was conducted using a no-choice arena and temperature-dependent development studies of the aphid at 15, 20, 22.5, 25, 27.5, 30, and 32.5 C. Nectarine va...

During the study on endophytic fungi of stone fruits including apricot, peach and nectarine in W Azarbaijan (NW Iran), a large number of isolates with Alternaria characteristics were isolated from different parts of these plants and studied taxonomically. Isolation was made based on endophytic fungal isolation method and following surface sterilization procedure. From 100 different plant sample...

in recent years, symptoms of virus diseases on stone fruits have been observed in wide range in golestan province. in order to study the important viruses on stone fruits, cherry, plum, nectarine, peach and apricot trees with symptoms such as mosaic, chlorosis, ring spot, shot hole, pale margins in leaves and dwarf in trees, sampling was done during 2005. putative infected plants were tested by...

Objective: Economic analysis was performed for the main horticultural crops in Buin Zahra (pistachio, peach, nectarine, and apple). There were dependent and independent variables in this research. Methods: The independent variables were planting method (mechanized and conventional), land area used for fruit production, and land ownership. The maximum energy used, mostly in the form of fossil fu...

damage caused by freezing can be the result of differences in cellular processes, including changes in membrane properties, interactions between macromolecular and enzymatic reactions. in this experiment, total soluble solids (tss) and relative water content of the reproductive buds of cultivars “j. h. hale”, “elberta,” “redhaven, ” “sorkh sefid mashhad” and “amsden” peaches, along with nectari...

Harvest maturity is closely related to peach fruit quality and has a very important effect on the fresh fruit market. Unfortunately, at present, it is difficult to determine the maturity level of peach fruits by artificial methods. The objectives of this study were to develop quadratic polynomial regression models using near-infrared spectroscopy that could determine the peel color difference, ...
