Assessment of the Tannin Contents of Grain Sorghum Cultivars

摘要

The Sorghum crop is adapted to the semi-arid environment of Pernambuco, northeastern Brazil, due to its tolerance for drought stress compared to maize, which is the traditional crop of the region. Research on sorghum was initiated in 1973, and the crop has been used as a feed source for cattle, poultry, and pork industries. Several sorghum genotypes have been evaluated for grain and/or forage; however, the IPA Cereal Improvement Program does not have enough information on the tannin content of cultivais. The objective of this study was to assess the tannin content of some cultivars and advanced elite lines developed by IPA's Sorghum Breeding Program.
