【摘要】 本文通过82—83年10个区试品种稳定性参数分析,得知我校新育成的品种甘春78—2302,在83和82两年第一组的5个和6个试验点上,产量分别占第一和第二位。回归系数分别为1.3748和1.3717,大于1。离回归均方分别为4.6123和2.9076,差异均不显著。结果表明,甘春78—2302具有在高产条件下的特殊稳定性,是一个适于河西高水肥条件种植的比较理想的品种。而且在一般条件下也是一个比较稳定的品种。更多还原

【Abstract】 The paper reports on stability parameter analysis of ten varieties of the regional test from 1982 to the 1983. The yield of Ganchun 78--230 2, our new wheat variety, is highiest and second highiest at fifth and sixth test spot of first group 1983. The coefficient of regression is 1. 37 4 and 1. 3717, respectively, it is more than 1. The mean squares of estimate regression is 4. 6123 and 2. 9076, respectively, variation is not singnificawt. The result showes: Ganchun 78--2302 has special stability under the conditions of high yield. It is a comparatively suitable and desirable variety under cultural conditions of wighlevel of water and fertility in Hexi. It is also a more stabils vaietg in genecal.更多还原
