Abstract
A haploid plant of Oryza perelenis (spontaleea type) was obtained through anther culture, which is one of the wild relatives of cultivated rice, O. sativa L.. In MI of PMCS of the haploid, no bivalent was observed in 70% of the cells examined, while I to 2 bivalents were met with in 30% of the cells.. Haploid perenleis was similar to haploid sativa not only, in meiotic chromosome beha-viour but also in morphology. It resulted in complete sterility in pollen and seed fcrtilities.
