108 RICE RATOONINGinto them. Breeding for cold tolerance at ratoon flowering, identifying suitablevarieties for different planting dates, and developing a suitable package ofagronomic practices for optimum yields are the needed research lines.Criteria to be considered in a breeding program are ratooning ability withmore basal tillers, resistance to insects and virus diseases, growth duration, anddesirable grain characteristics.REFERENCES CITED1.
