Introduction Different barley varieties have been shown to affect in vitro dry-matter digestibility (IVDMD), ruminal starch digestion and animal performance (Boss and Bowman, 1996). Some of these differences may be due to differences in site and extent of nutrient digestion among barley varieties. Little information is available on digestive characteristics of different barley varieties and sev...

A study was conducted to investigate the bioaccumulation of arsenic by twelve different high yielding, hybrid and local rice varieties, cultivated in the Nadia district, West Bengal (India). The results showed that rice plant accumulated arsenic from irrigation water but, the magnitude of accumulation was found to vary with the rice varieties. Some of the examined rice varieties (like IET 4094,...

Red rice is an interfertile, weedy form of cultivated rice (Oryza sativa L.) that competes aggressively with the crop in the southern US, reducing yields and contaminating harvests. No wild Oryza species occur in North America and the weed has been proposed to have evolved through multiple mechanisms, including “de-domestication” of US crop cultivars, accidental introduction of Asian weeds, and...

The effort of this work was to prove whether there exists any relation between stress factors caused by content of cadmium and zinc, and content and composition of opium alkaloids codeine, morphine, narcotine (noscapine) and papaverine contained in poppy seeds and capsules (Papaver somniferum L.) in 14 samples of 8 varieties cultivated in 8 localities in 2003.

www.bioversityinternational.org Assessing the genetic variability of crops is required to identify and develop cultivars (cultivated varieties) suitable for speci c growing conditions and speci c economic, social and environmental needs. Modern breeding relies on the identi cation of DNA regions that control complex traits of agronomic interest, such as resistance to drought, yield and plant he...

Let X/K be an absolutely simple abelian variety over a number field; we study whether the reductions Xp tend to be simple, too. We show that if End(X) is a definite quaternion algebra, then the reduction Xp is geometrically isogenous to the self-product of an absolutely simple abelian variety for p in a set of positive density, while if X is of Mumford type, then Xp is simple for almost all p. ...

Background: Arsenic and heavy metals are implicated in causation of CKDu among farmers in dry zone of Sri Lanka. Rice has been identified as a major source of arsenic in research carried out in other countries. We analyzed 120 samples of new improved varieties (NIVs) and 50 samples of traditional varieties (TV) of rice for total arsenic content. Findings: Rice cultivated in Sri Lanka is contami...

The present work dealt with RAPD markers for genetic diversity comparison estimation in twenty three cotton varieties of Bt and non-Bt cotton cultivars belonging to two cultivated species of cotton in Andhra Pradesh state, India.Variations among twenty three different cotton varieties were analyzed with selected 40 RAPD primers using the polymerase chain reaction (PCR). All the primers produced...

The nutritional and antioxidant composition of four tomato Portuguese farmer' varieties widely cultivated in homegardens was determined. The analysed components included macronutrients, individual profiles of sugars and fatty acids by chromatographic techniques, hydrophilic antioxidants such as vitamin C, phenolics, flavonols and anthocyanins, and lipophilic antioxidants such as tocopherols, β-...

The objective of this work was to evaluate the genetic variation of trypsin inhibitor in cultivated (Glycine max L.) and wild (Glycine soja Siebold & Zucc.) soybean varieties. Genetic variations of the Kunitz trypsin inhibitor, represented by a 21‐kD protein (KTI), and of the Bowman‐Birk trypsin–chymotrypsin inhibitor (BBI) were evaluated in cultivated (G. max) and wild (G. soja) soybean variet...
