Genetic Diversity in Triticale Breeding Lines, Stored in IPGR Sadovo

Abstract

A three-year study (2015-2017) of 24 breeding lines and varieties of triticale in the experimental field of IPGR Sadovo was conducted. The experience is sown in a block scheme in 3 replications, with a randomized distribution of repeat variants with a plot size of 10 m2. As a standard in the comparative assessment were used the varieties Sadovo 1 and AD72-91. The following indicators are obtained: date of heading and morphological features: plant height (cm), weight of 1000 grains (g) and average yield (kg/da). The aim of the study is to establish the variation of economical traits and the presence of genetic diversity in the triticale breeding lines in order their more effectively utilization in the breeding process. Under the specific conditions of the test period the yields ranged from 516,40 kg/da for A1BM0132 (Т-139) to 711,40 kg/da for A6BM0193 (Т-218), and the average crop yield for the three-year period was 644,3 kg/da. Only two breeding lines – A1BM0018 (ТС-128 Sadovetz) and A6BM0193 (Т-218) have a yield above 700 kg/da. On the basis of the cluster analysis performed on economical traits, the studied triticale collection is divided into four groups with genotypes with similar characteristics.
