HIERARCHIC CROSSING DESIGN IN ESTIMATION GENETIC CONTROL QUANTITATIVE TRAITS OF STRAWBERRY (Fragaria × ananassa Duch.)

Abstract

The aim of the research was to assess genetic control, heritability and correlation of some quantitative characters on the basis of hierarchic crossing scheme. In the experiment two systems of classification were applied. In the first one superior classification was made according male forms (5♂ × 4♀) and in the second one female forms were superior (10♀ × 3♂). Genetic control for most analysed traits was the same regardless of classification system. Only in case of yield genetic control was different in paternal than in maternal classification. Additive genetic components were essential in determining the time of flowering, whereas non-additive ones in determining the number of stolons. The high value of broad-sense heritability for most cases suggests large genetic influence on analysed characteristics.
