New pulse crops varieties more productive as medics should be made available to breeders located in semi-arid region of Algeria. So, and through two years of testing, pods yield and seeds production of twenty populations belonging to species M.intertexta , M.ciliaris, M.polymorpha , M.Truncatula and an introduced population M.muricoleptis is an Australian cultivar (Jemalong) are appreciated.Pods' yields of year 2013 vary between 78,66g/m² with poly27 and 3637,33g/m² with I107. Values of the second essay (2015) are different, they vary between 40,89g /m² with Poly236 and 464,36 g/m² with I11.The cultivar Jemalong offers a yield of 172,4 g/m². The corresponding seed yields also show a low production in year 2015. The ratio leaf / stem varies between 1,03 and 5. The average of yields in dry matter of 27 populations in 2013 was of 457,79g/m2 against 127,41 g/m² in 18 populations in 2015. Jemalong cultivar records a yield of 12,8g/m². For the same dose of seed, number of plants by square meter varies between 44 and 112. Number of stems by square meter varies between 136 in C204 and 420 in I52..The average width of population's ramifications varies between 13cm in Tr334 and 44 cm in I52, The Jemalong cultivar offers an average of 17cm. So, production results of medicks depend of weather conditions in littoral zone of lower altitude than 600-700m. In steppe zones, we recommend to make tests in situ with these same populations.
