Mean performance of various potato (Solanum tuberosum L.) genotypes

The present investigation was carried out at the Experimental Field, Division of Vegetable Science, SKUAST-K, Shalimar, during Kharif 2018. The experiment was laid out in complete randomized block design with three replications. Twelve potato genotypes were evaluated for various qualitative and quantitative traits. Analysis of variance revealed significant differences among genotypes for all the traits. The observations were recorded on days to initiation of germination, plant height (cm), plant spread (cm), stem diameter (cm), number of stems hill-1, leaf area (cm2), number of tubers plant-1, total tuber yield hectare-1 (q), specific gravity, dry matter (%), soluble solid content (0Brix), vitamin C (mg100g-1), reducing sugars (%) and non reducing sugars (%). The genotypes which showed highest yield potential were P-18 (309.00 qha-1) followed by P-20 (307.81qha-1), Shalimar potato-1 (305.11 qha-1) and CP-2187 (304.50 qha-1).
