| Abstract: | Huaimai 25 is a new wheat cultivar with high yield and wide adaptability released by Huaiyin District Institute of Agricultural Sciences of Jiangsu Province. This paper analyzed its yield formation and stability by the data from many years′ national and regional tests in order to provide reference for the current high yield wheat breeding. The results showed that Huaimai 25 achieved extreme significant yield increase for 2 successive years in southern Huang|Huai Winter Wheat Regional Test. During the 3 years′ test, the average productive ear numbers were 648×104/hm2, kernels per spike were 37, and per 1 000|grain weight was about 38 g. The 3 yield factors of this cultivar are well coordinated. Huaimai 25 has wide and strong adaptability. Both its dynamic and static stability are good. |
