远缘杂交小麦新品种小偃597的特性分析

小麦品种的高产稳产及适应性是优良小麦品种的必备条件。某一个小麦品种只要具有了高产、稳产、适应性强的特性,就能在生产上长期推广应用,才能取得较大的社会效益和经济效益。本研究利用1997～1999三年陕西省关中灌区高肥组区域试验产量结果,用高稳系数法和回归系数分析法对小偃597的高产稳产及适应性进行了分析。结果表明:小偃597三年的高稳系数分别为:12.2%、11.3%、19.0%分别低于对照品种;回归系数(b)三年分别为:0.84、1.00、0.95。说明小偃597高产稳产性要优于对照品种,同时小偃597还具有广泛的适应性。

The Characteristic Analysed of new Wheat Variety Xiaoyan 597 Derived from Distant Hybridization

High-yield stability and adaptability are prerequisite to good wheat varieties. Only a variety with characters of high-yield stability and adaptability can be applied to production for a long period, and brings good social and economic benefits. Based on the data of wheat variety regional tests of high fertility group in Guanzhong irrigated area, Shaanxi province from 1997 to 1999, high-yield, stability and adaptability of Xiaoyan 597 were analysed with high stability coefficient and regression coefficient. The results showed that the high steady coefficient of Xiaoyan 597 in the three years is 12.2%, 11.3% and 19.0% respectively, and lower than the contrast. The regression coefficient of Xiaoyan 597 in the three years is 0.84, 1.00 and 0.95 respectively. It is demonstrated that Xiaoyan 597 is better in high-yield and stability than the contrast. It has broad adaptability.
