Description
A germplasm collection was undertaken in Sardinia (Italy) to study the ecology and distribution of burr medic to obtain genetic material to start a breeding programme. Burr medic was found at 0-1000 m (asl), in all types of soil with a pH between 5 and 8,5, Most populations were classified as var. v11lgarls Shin., but a few of them were polymorpha and brevbpl11a Heyn, The morphological characteristics of the plants, pods and seed showed a height variability between populations, The average number of pods per plant was 331 (min. 40 - max. 599), average number of seeds in each pod was 4.5 (min. 3 • max. 7) and the average weight of 1000 seeds was 2.44 g (min. 1.34 - max. 4.08). Seed production per plant averaged 3.7 g (min. 0.9 • max, 11.2)
