The genetic material consisting of 48 potato genotypes (such as., Carlita, Radeo, Akria, Multa, Voyager, Eldina, Felcina, Asterix, Febula, Petronese, Marrabel, Futuri, Courage, Innovator, Martin, Raja, Fontany, Granula, Balaka, Ultra, Lura, Remarka, Quiency, Cardinal, Durby, Diamont, Callwhite, Belini, Senori, Victoria, Blondy, Prelude, Atlas, Cheiftain, Banana, Blue mountain, All red, Vanilla, Russet burbank, Gaforgown, Shaita white, Shaita red, Shepodi, Chipita, Indurcani, Lalpakri, Challisha and Hagrai) were grown at Botanical Research Field at Rajshahi University, Rajshahi, Bangladesh during the rabi crop season of 2007-2008. The experimental was laid out in a Randomized Complete Block Design with three replications. The field size for the experiment was 20×12 m. Whole experiment field was divided into three blocks and the size of each block was 3 m × 20 m. Each replication comprised one block. There were 48 rows in each replication. At the final land preparation recommended doses of manure and fertilizers viz., 10 tons of cow dung, 326-217-250 kg of urea, triple super phosphate and murate of potash per hectare were used. The potato tubers were planted during first week of November for three years. Intercultural operations like weeding, irrigation, mulching and earthing up were performed as and when necessary. Indofile M-45 (0.2%) was sprayed at 15 days interval commencing from 30 days after planting for prevention of fungal disease. Ten potato plants were selected at randomly in each replication and observations were recorded for plant height at 50 days after plantation (PH50DAP), plant height at 60 days after plantation (PH60DAP), plant height at 70 days after plantation (PH70DAP), fresh weight /plant at 70 days after plantation (FWP70DAP), fresh weight /plant at 80 days after plantation (FWP80DAP), main shoot number/plant (MSNP), number of tubers/plant (NTP), number of leaves/plant (NLP), tuber fresh weight/plant at 80 days after plantation (TFWP80DAP) and tuber fresh weight at 90 days after plantation (TFWP90DAP). Genotypic (GCV) and phenotypic co-efficient of variation (PCV), heritability in broad sense (h2b), genetic advance as % of mean (GA %), genotypic (rg) and phenotypic (rp) correlation coefficients and path analysis were done. The above calculations were done for all studied characters.
