Ability performance for some economic traits in gladiolus (Gladiolus hybrida)

Abstract

Stability performance of (10) elite cultivars for important floral traits (floretslspike and spike length) across 5 random locations (environments) revealed that mean square deviation from regression was non-significant except for 'Apple Blossom', 'Moralla' and 'Sancere' for floretslspike and for spike length in all the cultivars except 'Friendship Pink' and 'Peter Pears' and hence prediction for stability was precise and reliable. The linear regression was non-significant for floretdspike revealing that most of the cultivars except 'Apple Blossom' and 'Big Time Supreme' were average in stability. Comparing their performance with the mean it was observed that 'Jackson Villa Gold', 'Peter Pears', 'Trader Horn', 'White Prosperity' and 'Yellow Stone' were well adapted to favourable environments only.
