Avaliação de características produtivas de clones de batata (Solanum Tuberosum) em ensaio de valor de cultivo e uso (vcu)

Abstract

The potato (Solanum tuberosum L.) stands out as one of the main vegetables cultivated in Brazil, presenting great economic importance both for fresh consumption and for industrial processing. In this context, genetic improvement programs seek to develop more productive materials, adapted to cultivation conditions and with characteristics suitable to the demands of the industry. This work aimed to evaluate the productive performance of potato clones from the Potato Genetic Improvement Program of the Federal University of Lavras (PROBATATA/UFLA), in a Value for Cultivation and Use (VCU) trial conducted in the municipality of Bambuí-MG. The experiment was installed in a randomized block design, with eight treatments and four replications. The following characteristics were evaluated: Total Number of Large Tubers (TNG), Total tuber weight (PTT), Total weight of large tubers (PTG), and Specific gravity (GE). The data obtained were subjected to analysis of variance, and the means were compared using the Scott-Knott test at a 5% probability level. The results showed significant differences between the evaluated materials for all studied characteristics. Clone CCF24-13 stood out for Total Tuber Weight, Total Number of Large Tubers, and Total Weight of Large Tubers, showing superior performance compared to the control cultivars. For the Specific Gravity characteristic, clones CCF25-06 and CCF25-08 presented the highest average values, indicating potential for use in industrial processing. The results highlight the potential of the evaluated clones for continued selection in the potato breeding program.
