Seleção Clonal de Umbu (Spondias Tuberosa Arr. Câmara)

Abstract

The semi-arid region of Brazil has a highly rich flora and the genus Spondias is widely found in this area, the umbuzeiro species has wide relevance for the semiarid region due to its productive potential and resistance to drought. Much progress has been made in research on umbu, mainly with a view to selecting clones with good agronomic characteristics, that is, clones with better productivity. The objective of this work was to determine which origin has the most accelerated development in the Southeast region of Goiás and to validate this for cultivation, with the aim of detecting nuances between clones selected from other regions of the country. Initially, 523 half-sib progenies from eight different origins were planted, four from the Southeast of Goiás and four from Bahia respectively. In the second stage, the experiment was conducted at the State University of Goiás, located in the municipality of Ipameri, GO in the field. In Height of Plant (ALTP), the origin that obtained the highest average was 44.48 there was an increase of 60%. The provenances of MV02 and MVBA01 exhibit high similarity to each other, as well as to MVBA02 and MV06. Provenance MV05 and MVPD have a lower level of similarity. The provenance that had a better development in the Southeast region of Goiás was the MV05 validating for cultivation.
