EVALUATION OF THE AVERAGE AGE OF VEGETABLE VARIETIES AS THE MEASURE OF VARIETAL REPLACEMENT ON THE POLISH MARKET IN THE YEARS 1988-2000

Urszula Braun-Młodecka

 

ABSTRACT



The analysis of the average age of varieties was carried out for 1535 varieties ascribed to 56 taxa and owned by both Polish and foreign breeders in the years 1988-2000. A vegetable variety was ca. 9 years old on average. For particular crops the value ranged from 1 for stem lettuce to 30 years for garden sorrel and turnip.

Key words: vegetable, average age, life cycle.
