Abstract

The knowledge of the plant growth pattern under specific climatic conditions (growth curve) is the basis for exploiting the maximum yield potential of potato genotypes. This study aimed to establish the growth curve, as well as to evaluate the agronomic characteristics, yield and specific gravity of tubers of three potato cultivars and one elite clone, thus providing basic information on the productive characteristics of these genotypes in the Brazilian Midwest. A randomized experimental block design, with three replications, was used. The dry mass accumulated by the tubers varied from 6.28 (Agata) to 9.75 t ha-1 [F183-08-01 (F183)]; the total mass of tubers from 35.33 (BRSIPR Bel) to 58.60 t ha-1 (F183); the mass of marketable tubers from 23.46 (Asterix) to 48.24 t ha-1 (F183); and the leaf area index from 2.86 (Agata) to 10.60 (F183). F183 showed a good adaptation to the cultivation conditions of the Federal District, being strongly recommended for this region.

KEYWORDS: Solanum tuberosum, dry mass and photoassimilates accumulation, specific gravity.
