In direct-seeded rice fields with a normal plant population (10 to 20 plants per square foot), rice plants generally produce two to five panicle-bearing tillers per plant compared to 10 to 30 tillers per plant in transplanted rice where more space is available between plants. Teqing).Observations were made of the grain colour, size and shape. Introduction of the cloned OSH1 gene into rice resulted in altered leaf morphology, which was similar to that of the maize morphological mutant Knotted-1 (Kn1), indicating that OSH1 is a rice gene homologous to the maize Kn1 gene.
