A Novel Rice Mutation Pool with Wide Variations

2003-06-01

Mutagenesis to Produce Wide Range of Variants

A NOVEL mutation pool of `Tainung 67' (TNG67) variety was developed by seed sodium azide (NaN3) mutagenesis containing more than 2,000 mutants (M12) with diverse variations including pathogen (Pyricularia oryzae, Xanthomonas campestris pv. oryzae) and insect (brown planthopper, white-back hopper) resistance, herbicide (bentazone and glyphosate), stress (UV, chilling) tolerance, chemical composition (starch, storage proteins, and aroma), taste quality, pericarp color of grain, and hundreds of agronomic variations in the growth stage, grain development, morphology, plant type, and yield capability.

Important Resource for Rice Breeding

This mutation pool shall serve as a rice resource for use in traditional studies such as genetics, breeding, physiology, and plant-microbe interaction, as well as in recent genomics and proteomics.
