Jujube (Ziziphus jujube) belongs to Rhamnaceae family. It is considered not only for medicinal usage, but also is cultivated as an ornamental plant due to its beautiful leaves and trunk. The first step in a plant breeding program is to collect native genotypes of a plant in a region and evaluate them for selection of superior genotypes. Jujube is grown naturally in some areas of Iran, as well a...

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...

Comparative studies have suggested that fruit traits, such as color, size, and protection, have evolved as covarying character complexes ("dispersal syndromes") in response to selection by frugivorous dispersers. However, many comparative studies of disperser-specific syndromes have used species as sampling units, a method which implicitly assumes that character complexes evolve de novo in each...

BACKGROUND Individual variations in child weight can be explained by genetic and behavioural susceptibility to obesity. Behavioural susceptibility can be expressed in appetite-related traits, e.g. food responsiveness. Research into such behavioural factors is important, as it can provide starting points for (preventive) interventions. OBJECTIVES To examine associations of children's appetitiv...

BACKGROUND AND AIMS When ecologically important plant traits are correlated they may be said to constitute an ecological 'strategy' dimension. Through identifying these dimensions and understanding their inter-relationships we gain insight into why particular trait combinations are favoured over others and into the implications of trait differences among species. Here we investigated relationsh...

grapevine is one of the very important fruit crops in iran the fruit of which is used as table grape and/or raisins. in this study, some genetic parameters (phenotypic and genetic correlation, heritability and repeatability), of some important traits in table grape (date of ripening, weight, length and width of berry as well as attachment to cluster strength) were evaluated. results showed high...

Why do ripe fleshy fruits contain secondary metabolites, sometimes in concentrations that make the fruits toxic to vertebrates? And how do the chemical and physical characteristics of fruits influence choice by frugivores? These questions have drawn the attention of those interested in understanding the adaptive roles of fruit traits (see Cipollini and Levey, 1997a, b,c; Cipollini, 2000). Howev...

The aim of this study was to detect polypeptides and genomic regions associated with fruit quality traits in a backcross generation using as parent the Argentinean cultivated tomato Caimanta of Solanum lycopersicum and the wild accession LA722 of S. pimpinellifolium. We tested two types of molecular marker: polypeptide profile (at two ripening stages, mature green and red ripe) and SRAP (sequen...

Enhancing water use efficiency of coriander (Coriandrum sativum L.) is a major focus for coriander breeding to cope with drought stress. The purpose of this study was; (a) to identify the predominant mechanism(s) of drought resistance in coriander and (b) to evaluate the genetic control mechanism(s) of traits associated with drought resistance and higher fruit yield. To reach this purpose, 15 h...
