title: Cytological analysis for meiotic patterns in wild rice (Oryza rufipogonGriff.).
abstract: The present report explores the chromosomal patterns during meiosis as a fundamental cell division study in wild rice (Oryza rufipogonGriff.). Cytological assays revealed normal meiosis in most cases but in some instances meiotic abnormalities such as weak desynapsis, univalent and quadrivalent formation, translocation, spindle abnormalities and precocious movement of chromosomes were noticed. Interestingly, this wild species also has the bi-nucleoli in first meiotic stages alike the cultivated species ofOryza(O. sativa). The present investigation emphatically addresses the questions of high adaptability of wild rice supported by high pollen fertility for their potential to strong fitness in nature.
