Seed productivity of tomato varieties of the Astrakhan selection

Abstract

The tomato culture is the leader in terms of cultivation area and production volume among food products of plant origin. Fruits contain a variety of minerals, sugars, fats, vitamins.
The goal of the study and study of economic characteristics: yield, marketability, average weight of fruits, weight of 1000 pieces. seeds and seed productivity of tomato varieties of two varieties, created by Astrakhan breeders and the use of the results obtained in planning seed production and the development of sale and purchase prices for varietal seeds to provide large farms, summer residents and owners of private farms with domestic seeds for the purpose of import substitution and suitable for various uses.
Methods. The experiments were carried out in the fields of Precaspian agrarian federal scientific center of the Russian academy of sciences according to well-known methods. Studied 9 salad and 7 for mechanized harvesting varieties of tomato.
Results. The article presents the results of studying the economic qualities and seed productivity of tomato varieties of two types, differing in shape, size, weight, fruit color and directions of use. The first group includes large-fruited salad varieties with non-cracking fruits, which are well stored and transported in brown maturity with an average fruit weight of 100-200 g or more. The second group – with plumshaped and elongated fruits, the average weight of which is 75-100 g, very dense, characterized by suitability for long-term transportation, and in terms of strength they are not inferior to foreign varieties and hybrids. The shape and weight of fruits of varieties of both groups are different, the yield and marketability of varieties is quite high, but the weight of 1000 seeds and seed productivity does not depend on these indicators, but is individual for each variety.
