The studies on NTA-2 agriculture characters showed that it closes glume, videlicet it doesn" t blossom. Compared with Aijiaonante 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.
