Análise sensorial e morfo-caracteristicas de diferentes clones de macaxeira oriundas do programa de melhoramento genético, cultivadas na Região Oeste do Pará

Abstract

Cassava is considered as one of the most important foods in the 30 diet, high consumption corresponds to high carbohydrate source. The objective 31 of this research was to evaluate the morphological characteristics of 15 clones of 32 macaxeira from the breeding program in the environmental conditions of the state 33 of Pará and to analyze the five clones that showed good productivity, ease of 34 peeling and adequate cooking time. The experiment was conducted in the 35 Tabocal community at km 27 of BR 163, Santarém, PA, located in the west of the 36 state, from May 2017 to June 2018. It is composed of 15 types of clones planted 37 in 9m lines, using 10 plants of each material, totalizing 150 plants, using the 38 spacing of 1 x 1 m. Sensory analysis was performed with 60 untrained testers, 39 using the hedonic scale and purchase intention as evaluation attributes. Data 40 were submitted to descriptive statistics using arithmetic mean and statistical 41 correlation. The clones presented a desirable agronomic performance, with clone 42 C8 with yield of 70.5 t ha-1, with high commercial root yield, number of roots, 43 plant height and shoot mass production. As for the sensorial analysis, the clone 44 C8 and C39 with greater acceptability by the tasters stands out, being the clone 45 C8 of greater approval in intention of purchase.
