Avaliação de genótipos de morangueiro na região de Pelotas para diferentes sistemas de cultivo

Abstract

Within the group of small fruits, the strawberry is the most produced and consumed fruit worldwide. There are numerous cultivars available to producers in the different producing areas, however, not all of them express their greater productive capacity due mainly to the lack of adaptation to the place. The adaptation of a genotype to the place where it is grown is dependent on several factors, mainly the genotype/ environment interaction, which may be different from the place where it was created, as well as the nutrition and management that can interfere with the success of the cultivation. Thus, the objective of the present study was to evaluate productive/agronomic and quality aspects of fruits from advanced selections of the genetic improvement program of Embrapa Temperate Climate strawberry, in different cultivation systems. The works were carried out in the years 2018 and 2019 in two different locations, a property located in the rural area of the municipality of Pelotas / RS (conventional system in the soil) and in a greenhouse belonging to Embrapa Temperate Climate (soilless system with recirculation nutrient solution). The cultivars Camino Real and Merced stand out for obtaining good productivity rates, good sized fruits and high physical-chemical quality in a conventional production system. Most advanced selections show an early behavior in relation to the cultivars evaluated. The Albion cultivar produces fruits with a high amount of soluble solids and an SS/ATT ratio in a soilless system. The selections 2015-35-25 and 2015-32-5 produce fruits with greater pulp firmness and less intense colors in an off-ground system. The 2015-35-22 selection demonstrated precocity for the start of production and late for the start of runners. The selections 2015-35-25, 2015-35-22 and 2015-35-6 stand out for presenting good productive indexes in the conventional system in the soil, producing fruits of good size and with high physical-chemical quality.
