Location and translocation of proanthocyanidins in malting barley

Location and translocation of proanthocyanidins in the grains of malting barley were tested with ant13-13, 17-104, 18-102 and the wild type malting barley varieties, using reciprocal crosses and microscopic observation. Reciprocal crosses between proanthocyanidins free mutants and wild types revealed that the phenotypic action of ant gene follows that of testa genes. And the testa of wild type barley was stained as red color with vanillin-HCI dye ascertaining the existance of proanthocyanidins. Proanthocyanidins in the barley grains were translocated to the seed from the early milk-stage conforming that ant genes are expressed in the testa of barley grain.
