Abstract

Legumes of the genus Medicago have particular ecological and agro-pastoral importance in the Mediterranean regions. This work was initiated in order to develop local species by identifying and selecting suitable cultivars. The main objective of this study is to assess the variation and relationships among agronomic traits in four sympatric populations of Medicago minima and Medicago truncatula collected in different sites of Djelfa. The trial was conducted during the 2016/2017 cropping season. The study focused on dry matter yield and pod and seed production. Populations were sown on 22 December 2016 at a density of 100 scarified seeds/ row of 1 m long spaced by 1.5 m. A randomized block design with 03 replications was used. Results obtained show that the populations of the three species differ significantly for all measured variables. Analysis of variance showed significant difference between populations. Higher degree of variation for the most of agronomic traits was observed among sympatric populations of M. minima and M. truncatula. From the obtained results, several populations had good biomass and high yield of seed and pod. These populations could be developed and exploited in pastures in Algeria.
