摘  要:
[目的]分析家蚕新品种杂交F1代主要经济性状的稳定性。[方法]采用Eberhart和Russell的稳定性分析模型Yij=iμ+βIj+iδj对6对皮斑双限性蚕品种杂交F1代(K32×丁22、K22×丁62、K23×丁22、K22×丁21、K22×丁61、K11×丁62)在4年8季主要经济性状的稳定性进行分析。[结果]结果表明:主要经济性状的稳定性在品种间存在明显差异,其中K32×丁22和K22×丁62属于高产稳产型品种,K23×丁22是稳产低产型品种,K22×丁21是不稳产低产型品种,K22×丁61是高产不稳产型品种,K11×丁62是超稳产中产型品种。[结论]对各对品种作出了客观、准确和全面的分析评价,为新蚕品种杂交F1代的筛选提供了理论依据。

摘  要:
[Objective] The research aimed to analyze the stability of 5 main economic characters on 6 marking silkworm varieties hybrid F1.[Method] The model,Yij=μi+βIj+δij,defining the stability parameters was used to perform the stability analysis of 5 main economic characters on 6 marking silkworm varieties over a series of environments.[Result] The results showed that the yield stability of each variety existed significant difference.K32×Ding22 and K22×Ding62 were two varieties of higher yield and good stability,K23×Ding22 was a variety of lower yield and good stability,K22×Ding21 was of lower yield and poor stability,K22×Ding61 was of higher yield and poor stability,K11×Ding62 was of meta-yield and good stability.[Conclusion] The study made the objective,accurate and comprehensive,providing the theoretical basis for screening the new silkworm variety hybrid F1.
