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。
Based on the analysis of the stability parameters of 10 cultivars from 1982 to 1983, we found that Ganchun 78-2302, a newly bred cultivar of our university, had the highest yield at the 5 and 6 test points of the first group in 83 and 82 years Respectively, the first and second place. Regression coefficients were 1.3748 and 1.3717, respectively, greater than one. The mean return from the regression was 4.6123 and 2.9076, respectively, with no significant difference. The results showed that Ganchun 78-2302 had special stability under high yielding conditions and was an ideal variety suitable for planting high water and fertilizer conditions in Hexi Corridor. And under normal conditions is a relatively stable variety.
