Studies on the genetic relationship between leaf edge color and glume tip color of YiDS with short day low temperature induced male sterility.

The glume tip color and leaf edge color of F_(1) and F_(2) derived from YiDS (purple glume tip and green leaf edge)/indica rice (green glume tip and green leaf edge) were studied. The results showed: 1) The purple of glume tip belonged to dominant inheritance, controlled by a pair of genes. 2) The leaf edge color was controlled by two pairs of genes, and one of them was probably the genes controlling color of glume tip. In addition, the experimental evidence further indicated that the hereditary basis controlling leaf edge color was different in indica and japonica rice, and no dominance-complement gene existed in japonica rice with green leaf edge.
