It shows stable male sterility,high stigma exsertion rate and good integrated agronomic characters. In 2013,it was technically identified by Chongqing Crop Variety Appraisal Committee,and its F1 hybrid combination Bayou 99（ Ba 1A / Neihui 99-14） was registered and released to commercial production by this committee in the same year.
