Twenty two diverse genotypes of vegetable cowpea (Vigna unguiculata subsp. Unguiculata [L.] Verde.) were evaluated for yield and a few related characters in a field experiment in randomized block design with three replications during 2011-12 at College of Agriculture, Vellayani, Trivandrum, Kerala. Discriminant function technique was adopted for the construction of selection index for yield using fruit yield per plant (X7) and the component characters viz., vine length (X1), days to first flowering (X2), pod length (X3), pod girth (X4), pod width (X5) and number of pods per plant (X6). These component characters showed relatively stronger association with yield and could form a valuable selection index for yield in this crop. Among Twenty two genotypes, VU 7 (1475.31) followed by VU 1 (1468.72) and VU14 (1426.92) recorded high selection index values and VU 3 (908.28), recorded low selection index value.
