Abstract: In 1976,six hundred green pollen plantlets from F1 hybrids of rice were obtained by anther culture with an average induction-frequency of 5%. Spontaneous doubling diploids among grown plants was about 50%. Between the spontaneous doubling plants (H1) grown in greenhouse and its progenes (H2) grown in field, significant relation in heading date (n=37, r= 0.714), no significant relation in grain weight (n = 37, r = 0.301), and no relation in fertility were found. This figure related partially to the more or less confusion in ploidy level of H1 pollen plants.
