Abstract
The article presents the results of studying the influence of quantitative traits on the barley plant performance. Thirty typical plants were selected for each of the 28 genotypes spring two-row barley cultivars and their height, productive tillering capacity, spike length, number and weight of kernels from the main spike, 1000-kernel weight, and performance were measured. As a result, we found significant positive correlations between the performance and productive tillering capacity and weight of kernels from the main spike. Path analysis showed that the weight of kernels from the main spike had the greatest direct effect on the plant performance (0.61). We have established that the paths “spike length – weight of kernels from the main spike – performance” and “kernel number per spike – weight of kernels from the main spike – performance” are of the greatest importance in select for the barley plant performance.
