Extending the collection of garlic (Allium sativum L.) accessions is an important means that is available for broadening the genetic variability of this cultivated plant, with regard to yield, quality, and tolerance to biotic and abiotic traits; it is also an important means for restoring fertility and flowering. In the framework of the EU project ‘Garlic and Health’, 120 garlic accessions were collected in Central Asia – the main centre of garlic diversity. Plants were documented and… 

Comprehensive Metabolite Profiling in Genetic Resources of Garlic (Allium sativum L.) Collected from Different Geographical Regions

Garlic (Allium sativum) is the second most important Allium crop that has been used as a vegetable and condiment from ancient times due to its characteristic flavor and taste. Although garlic is a

Agronomic performance, flowering, physicochemical characteristics and genetic divergence in garlic accessions from Brazil

The evaluation of garlic accessions is important in the search for superior, adapted and flowering cultivars for botanical seed production. The objective of this work was to assess the agronomic

Unlocking variability: inherent variation and developmental traits of garlic plants originated from sexual reproduction

A nucleotide binding site profiling marker technology was applied to provide conclusive evidence for the cross-pollination nature of garlic, and to compare the levels of polymorphism between progeny derived from a single mother clone fertilized by several pollinators.

Traditional and Novel Approaches in Garlic (Allium sativum L.) Breeding

Large investments are involved in the developing of seed-propagated garlic and breeding via hybridization, but the advantages of this approach for the future improvement of modern garlic are evident.

Characteristics of chemical components in genetic resources of garlic Allium sativum collected from all over the world

It was suggested that garlic’s transition of from sexual propagation to asexual (vegetative) propagation and changes in the chemical composition of the bulbs would have occurred in the process of expanding garlic cultivation and obtained high environmental adaptability with these transitions and changes via artificial selection.

Garlic Cultivation for High Health-Value

Experiments performed under fully controlled conditions showed that sulfur fertilisation as well as light conditions could also have an impact on the organosulfur composition of garlic bulbs, however, the interaction with the genotype has to be considered as spring-variety and winter-varieties did not react the same way to variations in fertilising and environmental conditions.

Male gametogenesis and sterility in garlic (Allium sativum L.): barriers on the way to fertilization and seed production

The present report provides first detailed description of the development of male gametophytes in 11 garlic genotypes varying in their fertility traits, and reveals significant differences between fertile and sterile genotypes, as well as between developmental stages of microsporogenesis.

Breeding and Genomic Approaches for Climate-Resilient Garlic

Various approaches and what has been done in these areas in different parts of the world to address the loss in crop yield which is likely to be caused by the biotic and abiotic stresses in the future are discussed.



Garlic (Allium sativum L.) and its wild relatives from Central Asia: evaluation for fertility potential

Further studies of flowering physiology and fertility restoration, should focus on bolting genotypes which produce inflorescences with a high ratio of normal flowers to topsets, and the size, number and rapidity of topset development varies significantly between genotypes.

Floral development in bolting garlic

For further studies of flowering physiology and fertility restoration, only clones which can differentiate the greatest proportion of normal flowers and the least of topsets in the apical meristem should be selected.

Infraspecific differentiation of garlic (Allium sativum L.) by isozyme and RAPD markers

An infraspecific classification of garlic with four major groups is proposed, using isozyme and RAPD markers to analyze and structure a collection of 300 accessions, many of which were gathered in Middle Asia close to the assumed center of origin.

Environmental Control of Garlic Growth and Florogenesis

It is concluded that in bolting garlic genotypes, manipulation of the environment, both before and after planting, can regulate the development of fl owers and regain fertility.

Fertile Clones of Garlic(Allium sativum L.) Abundant around the Tien Shan Mountains.

Garlic (A. sativum L.) clones were collected around the Tien Shan Mountains of Central Asia in 1994, and regular meiosis of pollen mother cells (PMCs) was observed in all the 39 examined clones, and 31 of the 35 examined clones produced fertile pollen.

Fertility of the Garlic Clones Collected in Soviet Central Asia

In order to seek fertile garlic, 31 clones were collected at the bazars of Moscow and six towns in Soviet Central Asia, and they were grown at Kagoshima. Meiosis was observed in 25 clones, which

Transformation and regeneration of garlic (Allium sativum L.) by Agrobacterium-mediated gene transfer

The temperature and number of days of co-cultivation with Agrobacterium tumefaciens was shown to be an important factor in transient expression of the uid A gene.

Characterization and classification of isozyme and morphological variation in a diverse collection of garlic clones

In this study, isozyme and morphological characters were analyzed for 110 diverse clones of garlic and the proposed progenitor species, A. longicuspis to suggest an artificial species separation.

Garlic Flowering in Response to Clone, Photoperiod, Growth Temperature, and Cold Storage

The effects of cold storage, photoperiod, and growth temperature on flowering incidence in four clones of garlic were studied and the highest flowering percentage in all garlic clones was achieved by growing plants at 10C under short Photoperiod with no cold storage of bulbs before planting.

Garlic and health.

An outline is presented of a European initiative which is aimed at the development of high quality garlic and the identification of biomarkers in atherosclerosis and cancer in humans for disease prevention.
