SELECTION OF POTENTIAL CHIPPING ADVANCED POTATO CLONES FOR THE PROCESSING INDUSTRY IN SOUTHERN AND EASTERN INDIA

A multi-location evaluation of 60 advanced processing clones was undertaken in the selected locations of south viz., Karnataka (Rabi and Kharif), Tamil Nadu (Kharif), Telangana (Rabi) and in Rabi crop season of West Bengal. Based on four-year trials, among advanced clones, viz., MP/12-126 consistently outperformed others during 2020-21, 2021-22 and 2022-23 in the Rabi season at different locations in Karnataka. However, MP/12-126 had almost similar yield but acceptable quality parameters as compared to controls in the Kharif seasons of Karnataka and Tamil Nadu. MP/14-171 was found to have higher yield and acceptable quality traits during 2020-21, 2021-22 in the rabi season of Karnataka and Kharif season of Tamil Nadu during 2023. During the rabi season of West Bengal (2020-21, 2022-23) and the rabi season of Karnataka (2022-23) advanced clone MP/15-698 had superior performance. MP/15-651 was found to be the most widely adapted clone as it has superior performance in all states either in Rabi/Kharif or both. Based on a four-year field trial at multiple locations (6 locations) and seasons (rabi and kharif), advanced clones namely MP/12-126, MP/14-171, MP/15-651 and MP/15-698 have the potential to provide a suitable alternative to the potato growers of south and eastern India as against the existing variety/varieties with acceptable chip colour, high dry matter (>20%) and lesser total potato defects including higher process grade potato yield as compared to controls.
