Identification,evaluation and molecular characterization of Stylosanthes seabrana － a potential and nutritious range legume having wider applicability in India
The Sty losanthes ( Fabaceae) genus has wide distribution in tropical, subtropical and temperate regions of the Americas, Africa and South East Asia.In India, Stylosanthes is extensively utilized in pastoral, agropastoral and silvipastoral systems (Chandra et al., 2006).The characterization of new species in genus Stylosanthes is always demanding.The newly identified S.seabrana is one such species established well in India without specific rhizobium and is superior in nutritional quality namely essential amino acids.Importance of this species has been also emphasized in other countries like China, Australia and Colombia ( Phailkaew et al., 2004 ).It is also better for leaf meal production and a suitable replacement of concentrate for livestock.However, limited numbers of lines in this species pose problems in its wider applications.Here, we report the recovery of ten new lines of S.seabrana from existing stocks of S.scabra utilizing STS markers which were further supported by morphological attributes.These lines were molecularly characterized using RAPD and STS markers to estimate the level of variability and genetic distance from S.scabra of which S.seabrana is one of the diploid progenitors ( Liu and Musial, 1997).These lines were also assessed for drought tolerance parameters like specific leaf area, osmolality, proline and soluble protein contents as better drought tolerance lines can be used in artificial synthesis of allo‐tetraploid S.scabra ( Tewari and Chandra,2008).
