Abstract
The potato (Solanum tuberosum L.) is a tuber belonging to the Solanaceae family. It is a crop of great economic importance due to its valuable nutritional composition and great versatility, and can be consumed fried or fresh. The potato chip market has developed significantly, causing pressure to increase the production of potatoes to meet the specific demands of this sector. However, in Brazil, chip production is mainly produced with the Atlantic variety, which is native to countries with a temperate climate and does not adapt very well to the tropical conditions of Brazil, resulting in a low utilization of its production potential. production. Therefore, the objective of the work was to evaluate the agronomic potential of potato clones with superior characteristics and good suitability for the chip industry. The experiment was carried out in the Olericulture Sector of the Instituto Federal de Educação, Ciência e Tecnologia de Minas Gerais, Campus Bambuí. 44 genetic materials were evaluated, of which 43 came from the potato genetic improvement program of the Universidade Federal de Lavras (PROBATATA-UFLA), previously selected for their tolerance to heat, and a control, the Atlantic cultivar. The design used was that of incomplete blocks. The evaluated traits were divided into productivity traits (dry mass content and average tuber weight) and appearance traits (tuber shape, eye depth, and overall tuber appearance). The data collected was subjected to analysis of variance and the means were compared using the Scott-Knott test at 5% probability. It was observed that some clones stood out more than others, such as clones CCF24-13, CCF22-10, CCF02-19, CCF25-08, CCF01-20, CCF23-01 and CCF03-09, which presented a high average weight of tubers. The clone CCF24-13 stands out, which showed good results in average weight, dry matter and tuber shape, being a promising clone, with desirable characteristics for the Chips industry.
