Yield stability of husk tomato (Physalis ixocarpa Brot.) II. Regression of genotypes on environment index

In Mexico, husk tomato (Physalis ixocarpa Brot.) is of increasing importance. However the research in this vegetable is insufficient and at present, there is not information relative to stability of performance. In the present study, the stability parameters of 12 husk tomato varieties were estimated. These varieties were evaluated in a randomized complete block desing, with four replications at each of five environments. Stability analysis was based on the model by Eberhart and Rusell (1966). All husk tomato varieties were stable, as their stability parameters were not different from the ideal values. ‘Mejorado 1’, ‘Mejorado 2’, ‘Mejorado 3’m ‘Criollo 3’, and ‘Rendidora’ seem to deserve a more refined study in future investigations to assess more extensively and accurately their comercial and breeding value, because of their perfomance in this study.
