Diversity and ecological niche modelling studies in Trifolium repens L. (White clover) in the region of north-western Himalaya, India

Trifolium repens L., commonly referred as white clover, is one of the important stoloniferous perennial range legume growing in temperate regions. The introduction forage legumes agro-ecosystem provides nitrogen enrichment soil and mobilizes other nutrients. Further, it has a tremendous potential to help rehabilitate grasslands decrease severe fodder shortage Himalayan region. In recent decades, collecting exploration species germplasm, including have been focus researchers. collected material shall act safe repository for different improvement programmes future germplasm stored Long Term Module National Gene Bank. this study, maximum entropy (MaxEnt) technique niche modelling was used explore probable new areas collection clover identify favorable climate characterization, cultivation, evaluation on-farm conservation Indian region, which comprises Jammu Kashmir Himachal Pradesh Uttarakhand. Significant variation observed plant height (15.5 37.6 cm), floret number per flower head (9.24 52.4), 100 seed weight (0.038 0.077), dry matter yield (6.2 15.1 g), leaf length (15.6 48.4 mm), width (11.2 39.6 mm). Very highly significant also ?V? marking. Dendrogram grouped 22 accessions into two clusters based on average linking method. Cluster I consisted five (IC-615818, IC- 615817,IC-622352, IC-615815, IC-622362), cluster- II could be sub-cluster-IIA sub-cluster- IIB. IIA consist six (IC- 622338, IC-622379, IC-622382, IC-622401, IC-622343 IC-62237), whereas cluster-IIB comprise 11 615814 615811, IC-615819, IC-622376, IC-622383, IC-615812, IC-622385, IC-615816, 615817, IC-622415 IC-622406). identifying cultivation & region comprising Union Territory states
