Abstract
NE India is considered as one of the centre of diversity of gingers having a total account of 24 species out of the 65 valid species found in the world. Manipur is one of the seven states of NE India with a mere area of 0.7% out of the total area of India. This paper focuses on the distribution, classification and evaluation of Hedychium species collected from Manipur. A total of 11 species were collected, identified and classified based on their morphological characteristics. The species are identified as Hedychium rubrum A.S. Rao et Verma, H. coronarium Koenig, H. chrysoleucum Hook., H. coccineum Buch.-Ham., H. thrysiforme Ker-Gawl., H. flavescens Carey ex Roscoe, H. stenopetalum Lodd., H. urophyllum Lodd., H. marginatum Clarke, H. villosum Wall. and H. elatum R. Brown. Evaluation of its botanical characteristics are also conducted. Analytical hierarchy process method is used in this paper to address the possibility of analysing the potential of these diverse Hedychium resources based on their ornamental, adaptability and utilisation potential which was evaluated on 12 indicator points. H. elatum scored the highest overall index making it the most potential species for sustainable exploitation followed by H. coronarium while H. villosum ranked the lowest.
