Characteristics of Dwarf Rice Mutants 1282 and 1287

In order to provide a reference for comprehensively using the dwarf rice mutants 1282 and 1287,the biological characteristics and agronomic traits of 1282 and 1287 were observed during November 2011-April 2012 in Sanya,Hainan.The results showed that the plant heights of 1282 and 1287 are 40.39 cm and 37.58 cm respectively.And there are some representative biological characteristics and agronomic traits from 1282 and 1287,such as order growth,upright plants,dark green leaves,purple sheaths,ordinary panicle type,non-sheathed panicle,slender grain shape,light yellow glumes,purple glume tip,high effective panicles,small tension angle of floret,relatively higher seed setting rate and so on.In conclusion,the prospects of utilizing 1282 and 1287 are satisfactory from their characteristics.
