Abstract

The knowledge of variability and correlation of essential phenotypic traits is an essential question in plants breeding. They make the determination of the criterions of genotypes selection with high yielding potential possible. Seed yield is a quantitative trait conditioned by many various factors both genetic and environmental. The correlation analysis as well as the analysis of regression (simple and multiple) are those statistical methods which are usually applied in investigation of the inter trial relationship. The aim of this paper was estimation of phenotypic traits of winter oilseed rape F1 CMS ogura hybrids and their parental forms influencing on the yield of seeds. Each of the field trials was carried out in a randomized complete block design with four replications. All hybrids and their parental forms were evaluated in four environments: in two growing seasons (2002/2003 and 2003/2004) and in two locations: Borowo and Zielęcin. In both vegetative seasons the following traits were observed: date of the beginning and of the end of flowering, length of flowering, elements of the yield structure: length of pod, number of seeds per pod, 1000 seeds weight, and after harvest: seed yield. The results of the experiments were analysed by multiple regression analysis using statistical package GenStat v. 7.1 (Payne et al. 2003). Obtained results show, that in examined genotypes in investigated four environments the short flovering period and length of pods influencen seed yield.
