STUDIES ON STABILITY FOR YIELD COMPONENT CHARACTERS AND CORRELATION OF STABILITY PARAMETERS IN COWPEA (Vigna unquiculata (L.) Walp)

Abstract

In any breeding programme, It is necessary to screen and identify phenotypically stable genotypes which could perform more or less uniformly under different environ- mental conditions. In view of great significance the present study was under taken to investigate the stability of yield and component characters in cowpea. Since the association between stability parameters of yield and its components furnish infor- mation subjected to environmental variations (Jatasra and Paroda, 1981), an attempt was also made to compute correlation coefficients between stability parameters of yield and component characters in cowpes.
