Abstract

Chemical composition including tannin content, and grain and agronomic characters including ear length, head type, glume colour, and threshability are reported for 18 genotypes with brown pericarp, 15 of which had been reported to be bird resistant. Agronomic characters varied significantly among the genotypes. Variation in tannin content was much larger than variation in the other constituents. Several of the bird-resistant genotypes contained only small quantities of tannin, while the three genotypes not reported to be bird resistant contained tannins in amounts that might be expected to confer resistance. Detailed polyphenol analysis on ten selected genotypes indicated that flavan-4-ol content was relatively high and it is thought that this may contribute to bird resistance
