Performance of potato (Solanum tuberosum L.) clones for growth, yield and quality

Abstract

This experiment was aimed to evaluate the performance of potato varieties for growth, yield and quality attributes. A field experiment was carried out at AICRP on Potato, Horticulture Research and Extension Centre (HREC), Somanahallikaval, Hassan district, Karnataka during the Kharif season 2025 under rainfed conditions with 15 potato genotypes (P-1, RH-2, P-14, P-45, P-46, C-15, C-17, P-16, P-53, P-76, P-82, P-93, P-99, P-7 and Kufri Himalini as the check) in a Randomized Complete Block Design (RCBD) with three replications. The results showed statistically significant variations in almost all of the parameters. The highest germination percentage at 20 DAP (93.00%), plant height at 75 DAP (67.57 cm), plant spread at 75 DAP (56.16 cm), total fresh weight of the plant at 75 DAP (287.21 g), total dry weight at 75 DAP of the plant (19.75 g) and leaf area per plant at 75 DAP (396.91 cm²), tuber length (8.70 cm), tuber weight (118.83 g), number of tubers per plant (9.23), total tuber yield per plot (13.67 kg), tuber yield per hectare (18.99 t/ha) and marketable yield per hectare (17.10 t/ha) was in P-1. The highest chlorophyll content (4.00 mg/g), tuber dry matter (24.40%) and starch (24.00%) content was observed in P-7 whereas, the highest reducing sugar (1.52%), non-reducing sugar (1.41%) and total sugar content (2.78%) was observed in C-17. In conclusion, results of the experiment revealed that P-1 variety resulted as best genotypes in terms of growth, yield and quality characters at HREC, Hassan during Kharif season.
