Correlation and path-coefficient analysis of yield and some traits related to the productivity of triticale with different geographical origin

Nikolay Neykov

Резюме: The aim of the present study is to investigate the relationship between some important components of yield, direct and indirect effects of these traits on yield in triticale accessions. The study was conducted in IRGR - Sadovo in the period 2016-2018 with 8 triticale varieties with different geographical origin. Statistically proven strong correlations (r = 0.803-0.933) between yield and plant height, spike length and mass per spike were found in all studied accessions. Path-coefficient analysis shows that the plant height, grain mass per spike and mass of 1000 grains have the highest direct effect on yield.
