The research experiments were conducted at ICAR-Central Potato Research Institute, Regional Station, Modipuram, Meerut, Uttar Pradesh during the early (2022) and main (2022-23) crop season to evaluate 50 potato (Solanum tuberosum) germplasm for tuber yield components in the North-central plains of India. On the pooled basis, the highest germination (%) was recorded for 12 genotypes namely, CP1454, CP1631, CP1651, CP3252, CP3334, CP3355, CP3414, CP3464, Kufri Bahar, Kufri Mohan, Kufri Garima and Kufri Ganga. The best performance for plant vigour was observed in Kufri Lima (4.3) followed by Kufri Mohan (4), Kufri Arun (3.9), Kufri Bahar, Kufri Garima, Kufri Surya and CP3085 (3.8). Early maturity was observed in CP3469 (3.75) followed by the genotypes namely, CP3469, CP1454, CP1471, CP3255, CP1651, CP2094, CP3266, CP3048, CP3050, CP3326, CP1648, CP3361, CP3252, CP3288, Kufri Mohan, Kufri Bahar, Kufri Surya, Kufri Pukhraj and Kufri Neelkanth (3.5). The highest marketable tuber numbers/plant were recorded for CP3353 (7) followed by CP3469, CP1651 and Kufri Sinduri (6). The highest total tuber number/plant was found in CP3353 (13) followed by CP3469, Kufri Sinduri, CP3385, CP3464 and Kufri Lalit (9), Kufri Ganga and CP1651 (8), Kufri Pukhraj, Kufri Lima, Kufri Garima, Kufri Mohan, Kufri Arun and CP3361 (7). The genotype Kufri Lima (310.8g) produced highest marketable yield/plant followed by Kufri Mohan (306g), Kufri Ganga (302g), Kufri Garima (294g), CP3294 (293g) and CP3413 (290g), Kufri Lalit (274g), CP3326, CP3469 (268g), Kufri Pukhraj (257g). The genotype like Kufri Mohan (360g) produced highest total tuber yield/ plant followed by Kufri Arun (358g), Kufri Lima (352g), Kufri Ganga (344g), Kufri Garima (336g), Kufri Lalit (323g), CP3413 (308g), Kufri Pukhraj (307g) and CP3294 (304g), CP3469 (288g) and CP3326 (277g). Overall, four genotypes CP3294, CP3469, CP3353 and Kufri Mohan were found promising genotypes in terms of germination, marketable tuber number/plant, total tuber yield/plant and total tuber numbers /plant.
