AVALIAÇÃO DE LINHAGENS DE SORGO VASSOURA NA REGIÃO DE VIÇOSA, MG, BRASIL

Abstract

The broom sorghum type is characterized by having lax panicle with short rachis and long andresistant branches, which makes it suitable for the manufacturing of brooms. This work evaluated the morphologicalcharacteristics of broom sorghum strains selected from accesses from different regions of Brazil. The experimentwas conducted at the Federal University of Viçosa, in Viçosa, MG, Brazil during the period of March to July 2009.The treatments consisted of nine broom sorghum lines and a commercial variety (Tietê), used as a control. Certaincharacteristics were determined such as plant height at flowering, diameter of the panicle stalk, panicle length andrachis length. The strains showed no differences in the diameter of the panicle stalk. The lineage SV08-001 standsout as to the length of the rachis and height of the plant. The lineages SV07-060 and SV07-032 were more promisingfor the production of quality brooms.
