As in many other crop species, also in Allium crops genetic erosion is taking place. In this mini review the current global state of the art is presented on Allium ex situ genetic resources and more in particular on onion genetic resources. Furthermore future possible actions are indicated to preserve the Allium genepool in a more effective way, amongst which a proposal to develop an Allium gen...

The experiment was conducted at the field laboratory of the Department of Genetics and Plant Breeding, Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur during November 2008 to March 2009 to estimate the genetic diversity of exotic and local onion. Ten genotypes of onion were evaluated for 16 characters in a randomized complete block design to study the genetic divergence throu...

Field experiment was conducted at CCS Haryana Agricultural University, Hisar during 2009-10 to investigate the diversity and abundance of insect pollinators on Allium cepa L. and correlate their incidence in relation to the abiotic environmental factors. Hymenopterans were found to be the most abundant (60%) followed by Lepidoptera, Diptera and Coleoptera. Variation in abundance was recorded ov...

Multiple shoot clumps or microclones were collected from two onion (Allium cepa L.) varieties for bulblet formation. MS medium supplemented with various concentrations of BAP, Kn, 2ip and NAA used. The height responded was observed 90% 80% in Taherpuri Indian variety, respectively on 2.0 mg l-1 BAP+0.5 NAA. best formation obtained containing 1.0 2ip. Finally, the rooted bulblets hardened establ...

OBJECTIVE Diabetes mellitus (DM) is associated with significant morbidity and mortality and its prevalence is increasing worldwide. Although conventional antidiabetic agents are known to ameliorate the symptoms of diabetes, they also may cause adverse effects. The purpose of this review was to organize and discuss various studies that have been previously conducted indicating the efficacy of Al...

Bulb color is an important consumer trait for onion (Allium cepa L., Allioideae, Asparagales). The bulbs accumulate a range of flavonoid compounds, including anthocyanins (red), flavonols (pale yellow), and chalcones (bright yellow). Flavonoid regulation is poorly characterized in onion and in other plants belonging to the Asparagales, despite being a major plant order containing many important...

Six essential oils (EOs) from the Alliaceae family, namely garlic (Allium sativum), onion (Allium cepa), leek (Allium porrum), Chinese chive (Allium tuberosum), shallot (Allium ascalonicum) and chive (Allium schoenoprasum) were characterized by GC and GC-MS and evaluated for their functional food properties. Antibacterial properties were tested on five food-borne pathogens: Two Gram-positive St...
