Evaluation of Red & Purple Skinned Advance Clones Suitable for Eastern Indo-Gangetic Plains of India

An experiment was conducted at ICAR Central Potato Research Institute, Regional Station, Patna, Bihar during the year 2021-2022 and 2022-2023 to evaluate 04 red skinned and 02 purple skinned Potato advance clones with 05 controls as popular potato varieties in confirmatory yield trials. The performance of advance clones was evaluated with respect to their yield and yield attributing traits, dry matter, nutritional status of the tubers. The experiment was planted in Randomized Block design with 03 replications, plant to plant distance was 20 cm and row to row distance 60 cm. The experiment was planted in two sets i.e. 75 days & 90 days duration crop. The potato clones PS/16-02 & PS/16-17 were selected on the basis of their remarkable high marketable tuber yield (26.29 and 22.45 t/ha in 75 days duration and 30.16 t/ha & 25.81 t/ha at 90 days duration crop respectively). The nutritional status of the tubers were high, tuber shape ovoid to round, colour purple (PS/16-02) & red (PS/16-17), shallow eyes and good organoleptic qualities after boiling and frying. The dry matter content of these selected advance clones were 20.17 & 20.42 respectively. The aim of the experiment was to evaluate the performance of advance clones for the above-mentioned traits and to select suitable advance clones for introduction in All India Coordinated Research Project on Potato.
