Evaluation of sweet potato (Ipomoea batatas (L.) Lam) genotypes under hill zone of Karnataka

Abstract

An experiment was undertaken to evaluate 30 different genotypes of sweet potato under hill zone of Karnataka. The evaluation study indicated that sufficient amount of variation existed among the genotypes for growth, yield, beta-carotene and titratable acidity. Genotype BSP-29 followed by BSP-18 were found superior for growth and yield parameters. Whereas BSP-23 and BSP-10 showed better performance for beta-carotene and titratable acidity, respectively. Significant variation in growth, yield parameters, beta-carotene and titratable acidity content among different genotypes of sweet potato may be due to the inherent genetic makeup of the genotype and influence of environmental conditions.
