Estimation of breeding material of interspecific hybrids Allium ascalonicum L. and Allium cepa L.

Abstract

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.
