    Genetic variability and correlations in cowpea Vigna Sinensis (L) savi
    (Kerala Agricultural University, 1979) Sreekumar, S G; Ramachandran Nair, Y; Saraswthy, P; Mary K George; Thomas, E J
    43 different genotypes of cowpea were grown in a Randomized block design with 2 replications during Khariff 1978. The different genetic parameters viz. coefficient of Phenotypic and genotypic variation, heritability in broad sense and genetic advance were calculated. The study revealed that all the characters showed positive phenotypic and genotypic correlations with yield. High heritability and genetic advance were noticed for 100 grain weight, yield of grain and yield of haulms. This indicate that selection based on the above characters will be very effective for the improvement of the crop.
