Researches regarding the minitubers production from potato lines

Abstract

In this study was done researches about minitubers production from 14 potato lines studied: TS 12-1488-1574, TS 12- 1489-1574, TS 12-1497-1573, TS 11-1475-1633, TS 12-1502-1675, TS 11-1472-1633, TS 11-1468-1633, TS 09-1441- 1525, TS 11-1486-1642, TS 12-1501-1582, TS 11-1480-1633, TS 96 -1207-169, TS 11-1467-1633, TS 09-1442-1525. The experience was monofactorial, in which the analyzed factor was the genotype, consisted of 14 variants, divided into 3 repetitions. As a control, the average of the determined values was determined for each parameter taken in the study. The parameters analyzed were: minitubers number / plant and minitubers weight minitubers / pl. TS 12-1489-1574 potato line was the most representative, being a productive line, which was distinguished by a number of 11.83 minitubers / plant and a significantly positive difference of + 4.21 comparative with control taken in the study. Weight of minitubers / plant was influenced by genotype, proving superiority TS11-1468-1633 potato line which had a good capacity to produce minitubers with high weight (295.17 g) (and a distinct significant difference, positive, to control +114,83). Thus, this potato line has a high potential for producing high yields.
