摘要
The objectives of this research were to assess genotype-environment (GE) interaction and to determine the stability and adaptability of advanced pea mutant lines for plant height, number of pods, number of seeds and seed weight per plant. All these traits measured are thought to be related in determining yield stability. The twenty-one lines and five initial cultivars were analysed in three years using randomized block experimental design with three replications. Genotype-environment interaction was analysed using linear regression techniques. Stability analysis demonstrated that two newly developed lines 2/950 - fasciata and 2/1384 - apulvinic type are less responsive to changed environmental conditions, having more stability and adaptation and can be grown over range of environments maintaining good mean values of the investigated characters.
