description [...]R&D process of hybrid rice proceeds generally slowly, not to mention the cultivars on a par with Thai fragrant rice, for quality of hybrid rice is decided by parental lines, especially for sterile line. [...]breeders have always attached importance to breeding highquality and high-heritability sterile lines. According to the two-year regional experiment, average yield per unit area was 8.15 t/hm2, increasing by 4.73%; daily yield was 71.85 kg/hm2, keeping 3.75% higher than that of the control. [...]seeds can be sown sparsely and the density at 225 kg/hm2 will be ideal. [...]seedlings can be cultivated in shallow water for tillering, so as to make seedlings strong in terms of resistance to insect, disease and lodging. supplementary measures taken to improve outcrossing rate To spray gibberellins at a proper dosage The dosage of gibberellins ranges from 225 to 300 g/hm2 in normal weather.
