Comparative study on X4 mutants of cowpea (Vigna sinensis L. Savi.) with reference to quantitative characters

Abstract

This thesis embodies the results of an investigation carried out in the Division of Agricultural Botany of the Agricultural College and Research Institute, Vellayani during the year 1965-66 to study the behaviour of X4 mutants of cowpea (Vigna ainensis L. Savi) with reference to certain quantitative economic characters. Eight mutant types selected from X3, along with the orginal (African) variety as control were raised in plots which were statistically laid out and replicated. The X4 mutants were compared among themselves as well as with the control with a view to isolate the economic types possessing desirable quantitative characters.
