The economic benefits of the production of double haploid for selection of white cabbage

Abstract

An important task of any state in the world is to ensure food security. The Russian Federation is the third largest cabbage producer in the world. In the conditions of the modern market, for ensuring successful competitiveness, selection must promptly respond to consumer requests. To reduce some stages of the selection process, we used the modern biotechnological method of culture of isolated microspores in vitro. This method allows one to get homozygous lines in the first generation. In the Federal Scientific Center for Vegetable Growing, the protocol for obtaining doubled haploid cabbage cultures has been optimized and successfully applied in practice. However, for expediency of implementation of the obtained lines in the selection and seed-growing process, it is important for us to know the economic efficiency of production. The paper presents the data on the basic costs of obtaining lines of white cabbage with traditional and modern biotechnological methods of selection. The article provides a comparative assessment of their cost-effectiveness in the selection of white cabbage. It is shown that the use of the biotechnological method in combination with the classical method of selection allows to obtain pure lines with 100% homozygosity for 3 years. At the same time, economic costs of producing lines, when using doubled haploid plants of white cabbage, are reduced in 2 times.
