摘要
利用八倍体小偃麦与普通小麦杂交,创造异附加系和异代换系小麦新种质。再用这些新种质与普通小麦杂交,培育出小麦新品种陕麦159。该品种半冬性,成熟早,产量高,品质优,综合抗病性好,适应性广。利用2005-2007年陕西省关中灌区中肥组区域试验结果,用高稳系数法和回归系数法对陕麦159的高产稳产性及适应性进行了分析。结果表明陕麦159两年的高稳系数分别为23%和9%,回归系数(b)两年分别为0.98和0.88,均低于对照品种。说明陕麦159高产稳产性优于对照品种,同时陕麦159还具有广泛的适应性。
Some new germplasm resources, alien addition lines and substitution lines, were created by cossing between octoploid Tritielytrigia types and Tritcum aestivum. With the germplasm resources and common wheat crossing, various types of wheat varieties were developed. The new varieties of wheat Shaanmai 159. Is semi-winterness, early maturity, high yield and good quality. The comprehensive disease resistance and adaptability is good. Next, uses in 2005--2007 year Shaanxi Province Guanzhong irrigation area the fat group regional test result, with the high steady method of correlates and the regression coefficient analytic method to the Shaanmai 159 high productions, the stable production and the compatibility has carried on the analysis. The results showed that the high steady coefficient of Shaanmai 159 in two years is 23%, 9% respectively, and lower than the contrast. The regression coefficient of Shaanmai 159 in the two years is 0.98, 0.88 respectively. It is demonstrated that Shanmai 159 is better in high-yield and stability than the contrast. It has broad adaptability.
