Evaluation of Red Skinned Advance Potato (Solanum tuberosum L.) Clones for Tuber Yield and Yield Parameters in Eastern Indo-gangetic Plains of India

Potato is a very important tuber crop used as staple vegetable in almost every household. India ranks second in potato production after China. The production of potato increased significantly during last six decades. There is remarkable increase in potato yield and production during last decade 1.10 and 5.98% per annum respectively at national level (Rani & Prasoon, 2013). The important yield and yield attributing traits are plant emergence (%), number of tubers/plots, tuber yield/plot and tuber dry matter (%). The present experiment was conducted at experimental field of ICAR- Central Potato Research Institute Regional Station Patna, Bihar. In this experiment data were recorded for plant emergence (%), seed wt (t/ha), foliage senescence (%), total and marketable tuber yield (t/ha), dry matter content in percentage (tuber), late blight (%), leaf spot disease (%) during 75- and 90-days crop. The trial was conducted in randomized block design with three replications to evaluate nine advance clones namely MS/11-664, MS/13-527, MS/14-1381, MSP/16-307, MSP/16-375, PS/11-47, PS/13-45, CP-4409 and Memphis along with seven potato varieties Kufri Khyati, Kufri Lalima, Kufri Lalit, Kufri Manik, Kufri Mohan, Kufri Pukhraj and K Neelkanth as controls during 2020-21 & 2021-22. The advance clones PS/13-45 (36.97t/ha), PS/11-47 (35.87t/ha), MS/11-664 (35.39t/ha) were good candidates for future new potato varieties in Eastern Indo Gangetic plains of India.
