Apricot (Prunus armeniaca L.) is an important fruit species in Turkey with high level of economic value. Sequence related amplified polymorphism (SRAP) markers were used for the first time to determine genetic diversity and relationships among Turkish and some foreign apricot cultivars. A total 87 bands were obtained from SRAP analysis and 63 of them (73%) were polymorphic. Similarity values am...

The aim of the study is to determine genetic diversity and relationships among olive cultivars native to Croatia and Turkey. A total of twenty olive (Olea europaea L.) cultivars including fourteen from Croatia and six common cultivars from Turkey were analyzed for genetic diversity and relationships by using six microsatellite markers (DCA05, DCA09, DCA18, GAPU71B, GAPU101, UDO43). The number o...

The following stress factors were tested for their effect on the susceptibility of Plutella xylostella (L.) to Bacillus thuringiensis Berliner: (a) exposure to low doses of the synthetic pyrethroid cypermethrin, (b) treatment with low doses of the secondary plant compound, azadirachtin and (c) development on partially resistant cabbage cultivars. B. thuringiensis-related mortality of cypermethr...

Red rod is an economically important disease of sugarcane caused by the fungus Colletotrichum falcatum. We used a simple sequence repeat (SSR)-based marker system to identify and analyze genetic relationships of red rot resistant and susceptible sugarcane cultivars grown in Pakistan. Twenty-one highly polymorphic SSR markers were used for DNA fingerprinting and genetic diversity analysis o...

Variations in leaf starch accumulation were observed among four species (wheat [Triticum aestivum L.], soybean [Glycine max L. Merr.], tobacco [Nicotiana tabacum L.], and red beet [Beta vulgaris L.]), nine peanut (Arachis hypogea L.) cultivars, and two specific peanut genotypes grown under different nutritional regimes. Among the genotypes tested, the activity of sucrose phosphate synthase was ...

The main objective of this study was to verify the association between the coefficient of parentage estimates and multivariate techniques which were used as measures of genetic diversity in cultivars. Thirty cotton cultivars were used for this purpose among which genetic diversity was estimated by means of the parentage coefficient (CP) and also through multivariate techniques employing microsa...

The number of transgenic cotton cultivars available for commercial production has increased greatly in recent years. Cotton producers now have multiple choices when choosing transgenic cotton cultivars. The choice of cultivar now dictates the insect and weed control programs that will or can be used. It is estimated that, in 2002, 55% of Arkansas’ cotton acreage was planted to a stacked-gene cu...

tandem with transgenic technology, while also questioning the validity of OCT performance data. Cotton (Gossypium hirsutum L.) cultivars transgenically enhanced A key role of cultivar testing is to provide unbiased to impart herbicide resistance to either bromoxynil [3,5-dibromoagronomic performance in a defined environment while 4-hydroxybenzonitrile; BXN (Bayer Advanced, Peoria, IL)] or glyph...

Citrullus colocynthis has been garnering interest in recent times as a potential biodiesel feed stockcrop due to its high seed oil content and natural adaptation drought The variability (OC), Oil yield (kg/ha) (OY) fatty acid composition were investigated for 12 accessions collected different localities Morocco. Analysis of the data revealed among accessions, with ranging between 17.1 24.3 % we...

Abstract Dihaploid production from elite tetraploid cultivars is key to both traditional and novel breeding approaches that seek simplify potato genetics. For this purpose, efficient widely compatible haploid inducers (HIs) are needed. We compared PL-4, a new HI developed at the International Potato Center, known HIs IvP101 IvP35. By pollination of lines, we showed PL-4 performed significantly ...
