Abstract

Nowadays breeding of oilseed rape in Poland and in the world develops in two directions: breeding of open pollinated varieties and breeding of hybrid varieties. The aim of this work was comparison of variability of yield-forming characters and yield and their phenotype and genotype relationship in experiments with open pollinated strains and F1 hybrids created by utilisation of CMS ogura system. In 2000/2001 in five locations two initial field experiments were conducted. Subject of the first experiment were 18 strains of winter oilseed rape and two standard varieties: Lisek and Kana. In the second experiment, 18 F1 hybrids of winter oilseed rape and two standard varieties: Lisek and hybrid variety F1 Buffalo were investigated. In both experiments yield and some determined yield plant characters: overwintering, earliness and duration of flowering, height of plants, height of canopy, and weight of 1000 seeds were estimated. Statistical analysis include a summary analysis of variance for locations, calculation of average, range, variation coefficient, index of heritability for the traits. Moreover, matrix of phenotype and genotype correlation between studied traits for both experiments was calculated. Also causual-consecutive relationship by the use of Wright method of path coefficients was estimated.
