Chorological data regarding true clovers (Trifolium L.) with different ploidy levels (Sect. Stenostomum G. et B.) I. Trifolium ochroleucon Huds., II. T. pannonicum Jacq. (in English)

Abstract

Trifolium ochroleucon Huds. is a diploid species in the polyploid series emerged in sect. Stenostomum. Further members of the series are named T. pannonicum Jacq. This second species is frequently cited fot its surprisingly high polyploidy level achieved in different populations. Research carried out by J. Farrago, 2^nd year student on the Faculty of Agriculture, Agronomy Institute Cluj-Napoca and his wife Melinda Farago, 3^rd year student on the Faculty of Biology, University, Cluj Napoca, has been focused on the study of dispersal, phenetic variability, genetics and breeding of this clover species. The chorological data collected in Romania are presented here in form of data files and dot maps (Tab. 2,3; Fig. 1,2). The structure of the data files is presented in Tab. 1; the stucture of the data and that of the dot maps follows the principles of Coger and Coher programs (see ref. 2,5).
