Abstract

The rice germplasm was screened, including those transgenic rice lines which accumulate β-carotene in there polished seed, for their carotenoid profile. Eighty-eight rice accessions were used for the screening. Seventy-nine were obtain from the IRRI germ plasm bank and were grown under the same field conditions at IRRI. Nine were collected from the origin countries. Seeds were polished with Kett grain polisher for at lest 1 min. The results from the screen showed a different carotenoid profile between polished and unpolished non-transgenic seeds.
