Evaluation of qualitative and quantities characteristics of advanced potato cultivars in spring culture

The experiment conduct in six location in order to introduction new potato with high yield and quality and replace them instead of old varieties. Experiment design was Random Complete Block Design (RCBD) with three replication. Area plot had 9 square meter. Harvest doing after deletion on plant from first and end row. The results revealed varieties have differenced for sugar change. The most variation concerning with varieties that have high sugar in harvest time. The results of combine analysis variance for location and year revealed for the most characters difference among varieties were significant and marketable yield for varieties of Akira, Marella, Burren and Banba was more than others varieties . The results of combine analysis variance for year in any location revealed for the most feature, difference among varieties was significant. The results of less significant difference ( LSD ) for percent of tuber dry matter showed GA2TTTB212 , FLAVIA and LADY ROZETA had the most amount. Akira had the most of specific weight . The results of correlation revealed correlation between tuber dry matter and specific weight was positive and significant. Correlation between sugar and specific weight in 1% level was negative and significant. The results of analysis variance for chips quality indicated MARELLA , SAICLON , AKIRA , COLOMBUS , SUCCESSFUL LIN (379007) had the most usually admission able , respectively. Correlation between usually admission able with chips color and chips soft was positive and significant. Correlation for admission able was more than chips soft. The results of others characters as a follow : correlation between length with number of main stem , total yield per plant , marketable yield per plant , number of tuber per plant and correlation of number of main stem with total yield , marketable yield and number of tuber per plant were significant and positive . Correlation between total yield per plant with marketable yield per plant was more than 98 percent. Correlation between number of tuber per plant with total yield and marketable yield was 75 and 74 percent , espectively .
