With the objective to identify previously unknown parental relationships among grapevine cultivars, 352 cultivars of Vitis vinifera L. were analyzed at 17 microsatellite loci. 29 were found to be duplicate genotypes of other cultivars. From the 323 unique genotypes, 89 possible pairs of parents were identified for 52 cultivars (i.e., each putative progeny cultivar shared at least one allele wit...

Previous studies on the effects and interactions of atmospheric carbon dioxide concentration ([CO2]) and air temperatures have shown large differences in growth and yield responses among Asian rice (Oryza sativa L.) cultivars. Far less attention has been focused on rice cultivars commonly grown in the Southern US. This 2-year study was conducted to determine the effects of [CO2] and air tempera...

Date palm (Phoenix dactylifera L.) is a monocot, dioecious and high longevity tropical plant greatly considered due to its high economic importance in Middle East. This investigation was carried out to detect genetic relations among 34 cultivars of Iranian date palm, both males and females, using ISSR markers. Accordingly, total DNA was extracted using CTAB method and was subjected to PCR ampli...

The genetic diversity of Saudi locally growing sorghum (Sorghum bicolor) cultivars has not been thoroughly characterized. To understand the genomic patterns of diversification in Saudi sorghum cultivars (N = 7), random amplified polymorphic DNA (RAPD) was used as a rapid, inexpensive method for providing information regarding genomic variability below the species level. Six commercially availab...

the present research was conducted to determine the percent self-incompatibility in some asian pear (pyrus serotina rehd.) as well in european pear (pyrus communis l.) cultivars. the experiment was carried out during 2006 and 2007 growing seasons. pollen grains were collected and tested for viability using in-vitro pollen culture. for microscopic examination of pollen tube growth in the style, ...

In the floriculture industry, the need for heat tolerant bedding plant cultivars is increasing because of the rising temperature around the world. A pot experiment was carried out to examine the impacts of four heat stress durations (0, 7, 14 and 21 days) on growth and ornamental traits to determine the relative heat tolerance of four cultivars of calendula (Calendula officinalis). Growth and d...

background and objectives: pomegranate, belonging to punicaceae family, is native of subtropical regions of iran and its neighborhood countries. iran has the richest germplasm resource of pomegranate and the first grade in cultivation area and production worldwide. physical and chemical properties of pomegranate cultivars vary in different developmental stages and have a large impact on the nut...

The volatile composition of white Agudelo, Blancolexitimo, Godello and red Serradelo cultivars (NW Spain) harvested at two different stages of ripening have been evaluated. C(6)-compounds, alcohols, volatile fatty acids, monoterpenes, C(13)-norisoprenoids, volatile phenols and carbonyl compounds were identified and quantified in free and glycosidically bound forms by gas chromatography-mass spe...

The effects of storage and heat processing on the content and composition of free fatty acids (FFA) in oats (Avena saliva L.) have been studied. Samples of three cultivars (Kapp, Mustang, and Svea) were stored at 30, 55, and 80% rh for 3.5 and 15.5 months before heat processing of hulled and dehulled grains. Results from gas chromatographic analysis of individual FFA were closely correlated (r ...
