The parthenogenetic ovaries induced by chemicals (PCPA) in vitro were hybride rice (indica) Fl’s.when they were cultured for 7-15 on SK3 and N6 media supplemented with GA3 0.5-2 ppm,the parthenogenetic plantlets of five combinations,such as Siyou No.30, were obtained.The regeneration rate of 5-10-day-old parthenogenetic ovaries grown on SK, and N6 was higher than that on MS. At a range of 0,5-2ppm, GA3 was able to induce parthenogenetic ovaries to form plantlets directly; NAA and 2, 4-D, to form calli.But KT and TRIA were not able to,Most of the parthenogenetic plantlets developed directly out of embryos: a few parthenogenetic ovaries first formed calli and then regenerated into green plantlets after their transfer on MS. Some of the parthenogenetic plantlets were haploids,others were natural diploids. Parthenogenetic plants showed their relative regu-lartiy and consistence in main argronomic traits during the PO2-PO3 generations.
