Determinig of performances of some potato (Solanumtuberosum L.) promising clones and commercial registeredvariety in the early vegetation conditions

This study was carried out in Tokat / Erbaa in 2017 to determine the performance of some promising advanced potato (Solanum tuberosum L.) clones and commercially registered varieties during early vegetation period. In this experiment, 20 potato varieties and variety candidates were examined.16 of them are potato varieties candidate and 4 of them are commercial registered potato varieties. The experiment was carried out in randomized block design with four replications. In the experiment, output time, output rate, plant growth shape, flower color, number of main stems, plant height, number of days of ripening, number of tubers per hearth, number of tubers per hearth, average tuber weight, total tuber yield, dry matter ratio, starch ratio , distribution of lump size and lump size were determined. The data obtained from the experiment were subjected to variance analysis in accordance with the establishment pattern of the experiment and the differences between the averages that were significant were compared according to the duncan multiple comparison test. The number of main stems of the varieties and varieties included in the trial ranged from 1.2 to 4 . Plant height ranged from 61.8 to 103.2 cm. Tuber weight ranged from 211 to 1034 g. Total tuber yield was between 545.6 and 4264 kg / da, and the highest yield were determined as Agria (4264 kg / da), GOU 7/12 (4039.6 kg / da), PAI-8- Of the 8-57 (3849.8 kg / da) respectively. The dry matter ratio ranged between 18.3-23.3%.
