Abstract

Extracts from young leaves of nine sweet cherry (Prunus avium L.) and eight sour cherry (Prunus cerasus L.) varieties, located in the germplasm collection of the 'Direção Regional de Agricultura da Beira Interior' (Fundão, Portugal), were analysed for five isozyme systems in order to characterise these varieties and detect problems of synonymies and homonymies that frequently present. The sweet and sour cherry varieties analyzed showed low isoenzymatic polymorphism, being PGM and PGI the systems with the highest discrimination power. These systems presented seven and five different zymogrames, respectively. IDH showed four patterns. SKDH and 6-PGD grouped the varieties only into two patterns. The evident and discriminant restrictions of this type of analysis had got results that have only been a complement for agronomical and morphological characterization.

Highlights

Sweet cherry (Prunus avium L., Rosaceae, 2n=16) is a deciduous, allogamous and generally self-incompatible species
Sour cherry is cultivated as sweet cherry rootstock
The objective of the present work is the identification and characterisation by isozyme analysis of 9 sweet cherry and 8 sour cherry varieties located at the germplasm collection of Fundão (Portugal)

Summary

Introduction

Sweet cherry (Prunus avium L., Rosaceae, 2n=16) is a deciduous, allogamous and generally self-incompatible species. It is cultivated for its edible fruits and for the wood. Sour cherry is cultivated as sweet cherry rootstock. Both species were originated around the Black and Caspian seas and these species were cultivated in temperate and cool regions. Both sweet and sour cherries were stretching slowly from the origin to others regions by the human and animal migrations (Moreno & Manzano, 2002). In the Iberian Peninsula the production of sweet and sour cherries reaches about 93,900 t per year
