ResumoMacroptilium is a legume genus with approximately 20 species, usually annual or biennial, herbaceous and distributed mainly in the Americas.It is widely used as a forage resource in grasslands and usually fixes atmospheric N.Martins et al. ( 2001) indicated that half-sib family selection with progeny testing is the most common plant breeding method used in Brazil.In the scientific literature, however, there are few studies dedicated to Macroptilium spp.This study evaluated morphological divergence among Macroptilium spp.progeny from accessions collected in 4 counties located in the semi-arid region of Pernambuco State, NE Brazil. MethodsThe experiment was carried out at the Animal Science Department of the Federal Rural University of Pernambuco (UFRPE), NE Brazil.Accessions of Macroptilium lathyroides were collected in Bom Jardim, Caetés, Sertânia and Tupanatinga counties, in the semiarid region of Pernambuco State.Seeds originating from 15 progeny of these accessions were planted and morphological characteristics of the seedlings assessed from October 2012 to January 2013.Seeds were planted in 20-L pots filled with soil (Ultisol) collected from the 0-20 cm soil layer in Arcoverde, PE.The soil presented the following chemical characteristics: pH (H 2 O) = 6.6;Mehlich-I P = 57 mg/dm 3 ; K + = 0.41cmol c /dm 3 ; Na + = 0.25 cmol c /dm 3 ; Ca 2+ + Mg 2+ = 3.65 cmol c /dm 3 ; Ca 2+ = 2.9 cmol c /dm 3 ;
