USE OF THE INDETERMINATE GAMETOPHYTE GENE FOR MAIZE IMPROVEMENT. |
摘要 |
A methodology for ascertaining gene function entails selection of mutations in androgenetic haploids which are produced by fertilizing a maize plant carrying the indeterminate gametophyte gene (ig) with pollen obtained from a mutagenized plant. Genes that control quantitative characters can be identified, for example, by fertilizing a first inbred carrying the ig gene with pollen from a second inbred that has been mutagenized. Changes in the phenotype of the hybrid progeny then are identified and characterized. A method for direct selection of androgenetic haploids is provided.
