COLLECTION FORMATION AND USE

Abstract

Purpose. Selection of the most promising starting material for breeding hybrids with improved biochemical composition of grain.

Results and discussion. The study of the maize samples allowed to estimate them on the traits of productivity and grain quality, to identify the samples with a high productivity level, grain number in ear, weight of 1000 grains, content of protein, oil, and starch in grain. There are allocated 4 lines which are sources of very high protein content; 20 samples with a very high oil content and 105 samples with a very high starch content in grain. These lines have a high and stable level of productivity and its components.

Conclusions. Using sources of productivity and grain quality in breeding program will improve its effectiveness and accelerate for 2-3 years creation of hybrids.
