BREEDING OF CUCUMBER IN SIBNIIRS (Siberian Research Institute of Plant Industry and Breeding) – HISTORY, RESULTS, PROSPECTS

Abstract

The main stages of the development of cucumber selection studies in the laboratory of seed selection and technology of cultivation of vegetable cultures of SibNIIRS for more than 40 years are presented. The severe climatic conditions of the region, the lack of a regionalized assortment, the high cost of cucumber products imported from other regions makes the task of creating local adapted varieties and hybrids very relevant. Particular attention in the laboratory is devoted to the study of the source material. More than 600 initial forms of different eco-geographical origin have been studied, and the best ones have been selected for use in breeding. The main directions in the selection of cucumber for open ground are precocity, yield, resistance to diseases, marketability of greenery, high technological properties. The main methods of selection are individual, mass selection, simple, complex hybridization, saturating and recurrent crossings, inbreeding. The State Register of Selection Achievements approved for the use of 3 bee-dusted varieties and 18 hetherosis parthenocarpic hybrids was created and introduced. An extensive linear material of various sexual types has been accumulated for heterotic selection of cucumber. In 2017 Siberian Research Institute of Plant Industry and Breeding was begin the cooperation on the creation of new varieties and hybrids of cucumber with LLC Geterosisnaya Selectiya. Preliminary results were obtained for nine lines of cucumber. Three samples with high yield and early maturity are revealed.
