Abstract

Orange and purple-fleshed sweet potato (Ipomoea batatas L.) genotypes have immense importance as cheap source of vitamins and antioxidants. Screening and evaluation of these genotypes for stress tolerance further add to their value as biofortified climate resilient food and nutrition source. In the present study, 15 orange-fleshed sweet potato genotypes were initially evaluated for yield and  Î²-carotene content through Initial Evaluation Trial (IET). Based on the yield performance in IET, five genotypes were selected and evaluated along with one check variety (Kamalasundari) in Uniform Regional Trial (URT). Both IET and URT were conducted in the farm of Regional Centre of Central Tuber Crops Research Institute, Bhubaneswar, Odisha, India (RC, CTCRI), under the All India Co-ordinated Research Project (AICRP) on tuber crops. Three genotypes selected through progressive evaluation in URT were tested further along with two check varieties (Kamalasundari and Gouri) by Multi-Location Trials (MLT) at four different locations (Balasore and Kendrapara-under saline conditions and Nuapada and Mangarajpur - under non-saline conditions) across Odisha and the farm of RC, CTCRI (under AICRP). In another study, under AICRP, the performance of four orange (SB-198/115, CIP-420027, CIPSWA-2 and ST-14) and one purple-fleshed (ST-13) genotypes were evaluated under On Farm Trials (OFT) at five different coastal locations (Kendrapara, Puri, Jagatsinghpur, Astaranga and Balasore - under saline conditions) across Odisha. Pooled analysis of yield and other characters through MLT and OFT revealed that all the six genotypes, ST-14, SB-198/115, CIPSWA-2, CIP-420027, CIP-440127 and ST-13 showed tolerance to soil salinity (6-8 dS m-1) with high tuber yield (16.69-22.49t ha-1), high β-carotene content (4-12 mg 100g-1) in orange-fleshed genotypes and anthocyanin content (85-90 mg 100g-1) in purple-fleshed genotype. All the six genotypes were found to perform better than the check varieties. The genotypes, ST-14, CIPSWA-2, CIP-420027, CIP-440127 and ST-13 are recommended for cultivation to supplement food and nutrition requirement in the economically backward coastal regions of Odisha.
