Abstract:

An investigation was carried out using 21 germplasm of Elephant foot yam including one national check to find out genetic divergence among the studied germplasm. The experiment was carried out at T.C.A., Dholi Research Farm of Dr. R.P.C.A.U., Pusa, Samastipur, Bihar, in a completely Randomized Block Design with two replications during 2018. Data were collected for ten characters viz., days to sprouting, pseudostem length (cm), pseudostem girth (cm), leaf canopy diameter (cm), chlorophyll content (SPAD), calcium oxalate (mg/100gm), dry matter (%), days to maturity, no. of cormels per plant and corm weight per plant (kg.). All the twenty one germplasm were grouped into five clusters. Highest inter cluster distance was observed between cluster IV and V (238.93) followed by cluster I and IV (229.41) and cluster III and V (172.38) on the basis of their genetic distances. Cluster IV showed maximum cluster mean values for corm weight per plant along with pseudostem girth, leaf canopy diameter, chlorophyll content, calcium oxalate, dry matter and days to maturity. Calcium oxalate followed by corm weight per plant, days taken for sprouting and number of cormels per plant showed maximum contribution towards total genetic divergence in Elephant foot yam germplasm.
