Compared with Aijiaonante (ANT) which is a natural mutant from NTH, NTA-2' s culm length increase and kilo grain weight lighten. The increased culm length of NTA-2 is mainly due to the elongation of every internodes.
对南特矮-2的性状分析表明：同南特号自然突变的矮脚南特相比，南特矮-2是全闭颖授粉：株高略高，各节间均有所增长；叶片较窄长，分蘖较少，茎秆较粗；穗长减小，结实率下降，千粒重较小。
