BREEDING OF A NEW TOMATO VARIETY “YUBILEY 25” AND RESULTS FROM THE STUDY OF ITS GROWTH, REPRODUCTION, BIOCHEMICAL AND ECONOMIC PROPETRIES

The creation of new tomato varietes of determinate type, suitable for cultivation without stakes, high yielding, early ripening, producing large fruits of high bilogical and gustatory qualities for fresh consumption, is a very important, but yet not satisfactory solved breeding problem in this country.

The presently cultivated indeterminate tomato varieties — Rutgers, Ideal, Triumph, Kecskemet, etc., are not suitable for industrial cultivation. These high-stemmed tomato varieties need removal of suckers and fastening on stakes or wire constructions, which require expenditure of more labour and means, on the one hand, and make mechanization more difficult and production — more expensive, on the other. Because of this and of the shortage of labour force, the management of agro-industrial complexes and cooperative farms is inclined to cut down the area planted with tomatoes, especially around the big consuming centres, as a result of which production of red tomatoes for the market is declining.

In order to solve this very important problem for the national economy we set to ourselves the task of developing a new tomato variety of determinate type which, as regards fruits, to possess the qualities of the indeterminate varieties, but to require less amount of hand labour and means for its cultivation. In this connection, we carried out the necessary studies on the growth, reproduction and economic properties of the newly developed tomato variety “Yubiley 25”. In this paper we present the results obtained from this study.
