STUDY OF THE RELATIONSHIPS BETWEEN QUANTITATIVE CHARACTERS BY PATH-ANALYSIS IN SECALE CEREALE
Abstract
The aim of the present study is the preparation of a complex evaluation of rye specimens from the National Collection in the phase “ear formation” with a view to their future use and conservation. The experimental work was conducted in the period 2009‑2012. 54 specimens were objects of research. The study was conducted in the experimental field of the Institute of Plant Genetic Resources (IPGR) – the town of Sadovo. By the parameter P0, the mathematical data processing was determined by the influence of unspecified factors (P≤0,15) by the formula P0 = √1- (P12 + P22 + ... + P2n-1 + 2P1P2r12 + ... +2Pn-2Pn-1rn-1.n-2), where Pj (j = 1, 2, ........., n-1) - Path the coefficients of the individual signs; rji (i = 1, 2, ..., n‑1, j = 2,3, ..., n) - coefficient of correlation between the signs.
