Abstract
For the successful selection of winter triticale, it is important to know the dependence of the main feature by which selection is carried out, from other quantitative signs of plants. Of particular importance are the patterns of interrelation of such signs as the productivity of the plant and its structural elements. The relationship between the indicators of economic and biological characteristics of winter triticale varieties was estimated using paired correlation coefficients. Defined, both close and medium correlation between quantitative features of plant productivity and its structural elements is established, which makes it expedient to carry out selections taking into account the relationships between the signs in the studied varieties. In 2015, a close relationship was observed between the signs: the length of the head spike - the density of the ear; fertility of the head spike – the number of grains from the head spike; the number of grains from the head spike – the mass of grain from the head spike; the mass of grain from the head spike - the mass of grain from the plant. In 2016 – the length of the head spike - the density of the spike; fertility of the head spike - the number of grains from the head spike; the mass of grain from the head spike - the mass of grain from the plant. The obtained data testify to the possibility of carrying out the selection of the winter triticale of the examined plants according to one of the characteristics taking into account the indicator of the other.
