    Correlation studies in groundnut
    (Kerala Agricultural University, 1993) Pushkaran, K; Gopinathan Nair, V
    For effecting dependable selection in breeding groundnut varieties suited to kharif uplands and summer rice fallows, genotypic correlation studies and path analysis were done based on 18 characters collected from 80 divergent groundnut varieties and the results compared and contrasted. There are differences in the direction, degree of relationship and relative effects for important characters on the economic trait on both the situations. Hence, in selecting ideal genotypes for the two situations, differential considerations had to be given for the component characters.

    Genetic analysis of yield and its components in fodder maize
    (Kerala Agricultural University, 1995) Sreekumar, S G; Suma Bai, D I
    Nine fodder maize types were evaluated in a randomized block design with three replications during summer 1992 at the College of Agriculture, Vellayani under the AICRP (Forage Crops). Genetic analysis of fodder yield and its components revealed that plant height and plant population recorded high genotypic coefficient of variation, heritability and genetic advance indicating that selection based on these characters will result in improving fodder yield. Highest genotypic correlation was observed between green and dry fodder yield and also between plant population and dry fodder yield. High heritability and high genetic advance observed for plant height indicate additive gene action and the reliability of this character during selection programmes for improving the yield.
