Screening of red skinned potato (Solanum tuberosum L.) hybrids for yield and its nutritional value

The present investigation was carried out during kharif, 2020-21 to study the growth, yield and nutritional value among eight red skinned potato (Solanum tuberosum L.) hybrids. The present investigation was carried out during kharif, 2020-21 to study the yield and its nutritional value of red skinned potato (Solanum tuberosum L.) hybrids. The experiment was laid out in Randomized Block Design with four replications at Department of Horticulture, Main Agricultural Research Station, UAS, Dharwad, Karnataka. Analysis of variance showed highly significant differences for all the twenty traits of red skinned potato hybrids. Among all the treatments, red potato hybrid P-46 recorded maximum percent emergence (100%), number of compound leaves (10.05) at 45 DAP, number of primary branches per plant (3.16) highest plant height was maximum in Kufri Manik (65.28 cm and 77.72 cm at 45 and 60 DAP respectively.), hybrid P-53 recorded highest fresh weight of shoot (159.83 g) and dry weight of shoot (31.92 g). hybrid P-46 recorded maximum circumference (14.13 cm), length of tuber (9.72 cm), number of tubers (9.45), weight of tuber peel (9.39 g), weight of tuber after peeling (62.28 g), average weight of tuber (71.57 g), total tuber yield per plant (260.15 g), total tuber yield per plot (15.62 kg) and total tuber yield per hectare (21.69 t) fallowed by the hybrid Kufri Mohan. It is due to increased number of compound leaves may helped in synthesis of synthates and inturn promotes initiation of stolons.
