Interspecific Crossing

Interspecific crossing is a promising approach for introgression of valuable traits to develop cultivars with improved characteristics. Allium fistulosum L. possesses numerous pest resistances that are lacking in the bulb onion (Allium cepa L.), including resistance to Stemphylium leaf blight (SLB). Advanced generations were produced by selfing and backcrossing to bulb onions of interspecific hybrids between A. cepa and A. fistulosum that showed resistance to SLB. Molecular classification of the cytoplasm established that all generations possessed normal (N) male−fertile cytoplasm of bulb onions. Genomic in situ hybridization (GISH) was used to study the chromosomal composition of the advanced generations and showed that most plants were allotetraploids possessing the complete diploid sets of both parental species. Because artificial doubling of chromosomes of the interspecific hybrids was not used, spontaneous polyploidization likely resulted from restitution gametes or somatic doubling. Recombinant chromosomes between A. cepa and A. fistulosum were identified, revealing that introgression of disease resistances to bulb onion should be possible.

Hybrid Forms

Relevance. Shallots are an independent botanical species. It easily crosses with onions, has a medium-sized bulb, keeps well, gives rich greens. Shallot and onion hybrids have a higher yield, less nesting, and a large bulb mass. Work on the creation of interspecific hybrids of shallots and onions has been under way since 2000.Methods. The aim of the research was to study the hybrids of Allium ascalonicum L. x Allium cepa L. and Allium cepa L. x Allium ascalonicum L. by a complex of characters in comparison with their maternal forms. Samples from the Urals were taken as initial forms for hybridization.Results. 268 promising hybrids were obtained, of which 33 were selected for further study. The results of the study showed the advantage of hybrid forms, where shallots were the parent form. A significant advantage of hybrids over parental forms was revealed in terms of yield, average and maximum bulb weight.

Essential oils extracted from spices, as natural antimicrobial agents, attract particular attention due to their possible role in food protection from microorganisms, and their nontoxicity, in contrast to the synthetic preservatives. In this work, inhibitory effect of Allium ampeloprasum and two onions (Allium cepa), Junski srebrnjak and Kupusinski jabucar, essential oils in different concentrations (1, 4, 7 and 10%) on three yeasts (Saccharomyces cerevisiae, Candida tropicalis and Rhodotorula sp.) and three moulds (Aspergillus tamarii, Penicillium griseofulvum and Eurotium amstelodami) was investigated. All three essential oils showed the strongest inhibitory effect against S. cerevisiae in concentration of only 1%. Among onions, Kupusinski jabucar essential oil had stronger influence to C. tropicalis, while Allium ampeloprasum essential oil did not show any influence on this yeast. Rhodotorula sp. was influenced only by Allium ampeloprasum essential oil. The strongest inhibitory effect on A. tamarii showed Kupusinski jabucar (57% of inhibition, in concentration of 10%), while on P. griseofulvum, the strongest influence showed Allium ampeloprasum essential oil (78.3% of inhibition, in concentration of 10%). Junski srebrnjak and Kupusinski jabucar essential oils, in concentrations of 7 and 10% respectively, completely inhibited the growth of E. amstelodami.
