Phenotypic Stability of Flowering and other Quantitative Characters in Forage Cowpea (Vigna Unguiculata (L.) Walp

Abstract

The varieties of loregn cowpes were evaluated for stability parameters with respect to tower initiation, main stem length, number of branches and loaf areas in eight environments, The varielles included in the study were: FOS 1, HFC 42-1. GFC 2, GFC 3, GFC 4, UPC 9020, EC 4216, C 152. C1 and 12-1-8 Presence of genotype x environment interaction was observed. The lineer component appeared to account for most of the interactions precant. Variety EC 4216 was most simble for flowering trait, C 152 for main stem length, GFC 4 for number of branches and 82-1-8 for leal area.
