Sweetpotato is a fast growing starchy root crop. It can be grown on a wide variety of soils. Soils of Sylhet region are classified into various soil series or soil groups. Several indigenous sweetpotato genotypes are distributed in Sylhet region. So far they are not being explored. From this point of view, the present study was conducted to evaluate the growth and yield performance of nine sweetpotato genotypes namely Local-1, Local-2, local-5, Local-8, Exotic-1, Exotic-2, Exotic-3, Exotic-4 and BARI SP-4. The evaluation was carried out on Ramgarh soil of North-Eastern Piedmont plains during November 2015 to March 2016 in a Randomized Complete Block Design with three replications. Morphology of leaves, vines, fibrous roots and storage roots as well as yield determinants were studied. Correlation study between morphological and yield attributes were also carried out. Correlation study revealed that primary vine number, total fresh weight, total dry matter, harvest index, storage root number plant-1, diameter of storage roots, fresh weight of storage roots were positively correlated with yield. The highest harvest index (HI) was observed in Local-1 (69.46%). The maximum number of storage roots plant-1 was in Exotic-2 (7.20). The longest storage roots were in Local-5 (14.13 cm) and thickest storage roots were in Local-8 (5.22 cm). The highest storage roots fresh weight plant-1 was obtained from Local-1 (826.10 g). The highest storage roots yield was in Local-1 (48.96 t ha-1) followed by Local-8 (42.60 t ha-1). It can be concluded that Local-1 and Local-8 would be suitable for higher yield whereas potentials of Local-2 and Exotic-3 suggested for further investigation.
