Use of primary trisomics has played an important role in genetics and breeding of rice. A great number of trisomics could be induced through anther culture of autotetraploid rice. In earlier work, trisomics of rice selected according to auricle distances from -2.5 cm to + 2.5 cm resulted in low selection efficiency. This paper reports on an efficient time to select trisomics.
