Please note the following problems relating to naming of the genes mentioned.
1. Definition of semidwarfness; restricted only to plant type useful for breedings.
2. Classification of dwarfing genes according to their effects on plant type.
3. Guide lines for grain shape and shattering.
4. A new system for heading or flowering time.
5. Reconsider action of genes for floating habit.
6. How to denote the 'Waxy' alleles and structure of wx locus.
7. Naming of the spotted leaf.
8. Standardization of gene symbols for hybrid sterility and hybrid weaknesses.
9. Naming and numberiiig of fertility restorers and male-sterility genes.
10. Naming of multiple alleles on isozyme loci.
11. Naming of gene symbols for blast resistance.
12. Naming of biochemical niarkers.
We would like to discuss these problems at the coming International Rice Genetics Symposium which will be held in 1990 at IRRI.
