Forty–four selected potato clones of TPS progenies were evaluated for Morph physiological characters .their relation to yield , the most efficient factors on total yield and marketable yield and correlation among characters were determined .The experimental design was Random Complete Block Design ( RCBD) with three replication during two years . The results of combine variance analysis arrived that difference among clones in most characters were significant at 1% level . Correlation of coefficient between total yield and marketable yield per hectare with most characters were positive and significant .Negative correlations were generally not significant .Only the correlation of percent of smart tuber per plant was negative and significant. The results of path analysis showed that marketable yield per plant had the most direct efficient on total yield per hectare and also, the number of ware tuber had the most indirect efficient on marketable yield per plant . The yield of ware and seed tuber had the most direct efficient on marketable yield per hectare, respectively. The result of heritability arrived that the most amount heritable feature were depth of eye , flesh color , tuber form ,the number of main stems , date of maturity and flowering , respectively . The efficient of heritability on yield and yield omponents were high too .
