Abstract

The use of intra-varietal crossing is an important element to increase seed yield and improve a variety. The aim of the research was to identify the influence of different options of intra-varietal pollination of sweet pepper on seed productivity and other quantitative traits.

It has been established, that re-pollination of sweet pepper within the variety in relation to self-pollination causes a reduction in the offspring of the period before fruit ripening by 3–7 days. For all options of pollination, there was also a significant increase in plant height by 7–8 cm, fruit weight by 7–16 g, the number of fruits on a plant by 2–6 units.

Different methods of re-pollination of plants significantly affected fruit productivity, increasing it by 62–106 %, increased seed yield from one fruit by 28 %. Seed productivity of sweet pepper plants increased by 78–163 % when re-pollination was used.

Options of using the pollen of different flowers (from 2–5 other plants) showed the greatest effect. This technique is one way to increase the yield of sweet pepper seeds
