利用内蒙古多点区域试验结果,采用联合方差分析及G.C.C.Tai(1971年)提出的有关品种稳定性的分析方法,对新育成高粱杂交种赤杂28进行了丰产性和稳产性分析。结果表明,赤杂28平均产量9 058.79kg/hm2,比对照品种敖杂1号增产11.95%,增产显著。赤杂28的遗传型稳定性统计参数:环境效应的直线响应为0.039 7、直线响应的离差为1.603 8。说明该品种在各试点的环境范围内不但高产,而且是一个产量较稳定的品种。
Based on the multi-point regional test results in Inner Mongolia and the analysis of the stability of cultivars introduced by G.C.C.Tai (1971), the analysis of the yield and stability of the newly-grown sorghum hybrid Chizu-28 was carried out. The results showed that the average yield of Akaza 28 was 9 058.79 kg / hm 2, which was 11.95% higher than that of the control Aoza 1, and the yield was significantly increased. The genetic stability of Akasaka 28 Statistical parameters: environmental effects linear response 0.039 7, the linear response of the dispersion of 1.603 8. This indicates that the variety is not only high-yielding within the experimental environment, but also a more stable variety.
