Yield Formation of Huaimai 25 with High Yield and Wide Adaptability

淮麦25是江苏徐淮地区淮阴农业科学研究所选育的高产广适小麦品种。用多年国家区域试验数据对该品种进行了产量形成及稳定性分析,以期为当前高产小麦育种提供借鉴。结果表明,淮麦25连续两年在国家黄淮南片冬小麦区域试验中增产均达极显著水平;平均有效穗数为648×104/hm2,穗粒数37粒,千粒重38 g左右,产量三因素协调;适应度广,适应性强,动态及静态稳定性好。

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 648×10^4/hm^2 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.
