- Abstract
Forty two orange-fleshed sweet potato hybrids were evaluated for storage root yield, β- carotene and dry matter content along with a control variety 'Sree Kanaka' in upland and lowland situations. In the upland condition, the root yield ranged from 3.0 - 20.0 t ha-1 and in lowland, from 3.0 - 30.0 t ha-1. Three hybrids yielded above 20 .0 t ha-1 in the upland condition and 7 hybrids yielded above 20.0 - 25.0 t ha-1 in the lowland condition and one hybrid, 30.0 t ha-1. The β-carotene values of the hybrids varied between 1 - 14 mg/100g.f.w. Majority of the hybrids (22) possessed a β-carotene value of 10 - 15 mg/100g.f.w. Two hybrids (106427-10 and 106035-9) possessed highest β-carotene value (14.37mg/100g.f.w). The dry matter content of the hybrids varied from 18.5 - 29.2%. In both the locations, dry matter content was negatively associated with carotene content.
