Abstract
The study has been conducted at the Education-Scientific Institute of Natural and Agrarian Sciences of Lugansk National University named Taras Shevchenko (Ukraine). The research was aimed at establishing the elements of agricultural technology that ensure the maximum yield of pure seeds of sterile analog of the maternal lines GE6A and GE57A when grown under group isolators. This study examined the structure of plant productivity of sterile analog when grown under group isolators with a width of row spacing of 70 and 45 cm, with a plant population of 40, 50, 60, and 70 thousand plants ha-1. The created conditions for growing plants under group isolators had different effects on the development of the vegetative mass of plants and quantitative characteristics of the productivity of plants of lines. A width of row spacing and crop density statistically influenced (P < 0.05) the formation of quantitative traits of plant productivity of maternal lines. Growing lines with a width row spacing of 45 cm at a plant density of 40-60 thousand ha-1 ensured an increase in the weight of head seeds in the sterile analog of the maternal line GE6A by 3.7-5.8 g, in the sterile analog of the maternal line GE57A - by 4.2-6.2 g. Each maternal line had an individual reaction to changes in growing conditions. A width of row spacing of 45 cm and a sowing density of 50 thousand plants/ha ensured the highest pure yield of seeds from a sieve with a hole size of 2.5 × 20 mm from one isolators of 16.0 kg and a maximum yield of 1.69 t ha-1 for the sterile analog of the maternal line GE6A. A width of row spacing of 45 cm and a sowing density of 50-60 thousand plants/ha ensured the highest pure yield of seeds from a sieve with a hole size of 2.5 × 20 mm from one isolators of 14.7-14.8 kg and a maximum yield of 1.55-1.57 t ha-1 for the sterile analog of the maternal line GE57A. The sterile analog of the maternal line GE6A, with a maximum yield level at a width of row spacing of 45 cm, produced a higher yield of 0.14-0.12 t ha-1 than the sterile analog of the maternal line GE57A. The research results allowed us to recommend the use of agricultural technology elements individually when growing maternal lines under group isolators.
