Study on agromorphological variation vis-à-vis geographical distribution in marvel grass (Dichanthium annulatum L. (Stapf.)).
Fifty-five accessions of perennial range grass, Dichanthium annulatum, were evaluated on the basis of agromorphological attributes. These accessions were collected from different parts of India representing varied agroecological situations. Wide diversity was observed among the accessions for different characters. The accessions were classified into eight clusters using the euclidian non hierarchical cluster analysis technique. The largest and smallest clusters were represented by nine and three accessions, respectively. The clustering pattern of the accessions was independent of their geographical distribution. Germplasm collected from different locations, though grouped into the same cluster, exhibited morphological diversity. The maximum cluster distance was 5.051, while the minimum was 1.801.
