摘要
以“甘春18号”、“高原602”、“晋2148”等13个品种(系)为材料,采用多年多点随机区组设计,对“甘春18号”进行了丰产性、稳定性及适应性分析,结果表明,“甘春18号”较对照增产显著,10个试点3年平均产量达7026.15kg/hm2,部分试点达9000kg/hm2具有较高的丰产潜力。“甘春18号”的回归系数b=0.973。采用基因型分组法分析,“甘春18号”位于高产稳产区间。因此,“甘春18号”属于丰产性、稳产性好。
Analysis on yielding, stability and adaptive faculty of 13 verieties (lines), such as Ganchun №.18, Gaoyuan 602, Jin 2148, and so on, were carried out by means of randomized block design with different sites and years. The result indicated that the mean yield of Ganchun № 18 was 7 226.15 kg/hm 2, the peak yield was 9 621 kg/hm 2. The regression coefficient of Ganchun № 18 was approximately 1 (b=0.973). Ganchun № 18 was located in the region of high and stable yield by means of grouping genotypes. The result indicated that Ganchun № 18 had higher and more stable yielding ability and wider adaptive faculty.
