    Formulation of a key for identification of the different types of pepper, Piper nigrum L.
    (Department of Agricultural Botany, College of Horticulture, Vellanikkara, 1982) Kanakamany, M T; KAU; Luckins, C Babu
    The studies reported herein were carried out in the Department of Agricultural Botany, College of Horticulture, Vellanikkara, during the year 1980-82 with a view to formulating a key for identification of different varieties of pepper. From the germ plasm collection maintained in the Pepper Research Scheme of the College, 45 types of uniform age were earmarked. Observations on twentyeight quantitative and seventeen qualitative characters were recorded from all the fortyfive types and the variability among the types was assessed. The study revealed that the material was highly variable with reference to many of the characters.

    Biometrical studies in banana
    (Department of Agricultural Botany, College of Horticulture, Vellanikkara, 1982) Rosamma, C A; KAU; Narayanan Namboodiri, K M
    Studies were undertaken with forty eight banana varieties belonging to five different genomic groups at the Banana Research Station, Kannara and Department of Agricultural Botany, College of Horticulture, Vellanikkara during 1981-82 to estimate the extent of genetic variability, association among the selected characters and its partition into direct and indirect effects through path coefficient analysis. Selection indices were worked out to estimate the efficiency of selection through discriminant function over straight selection or vice versa.

    IC divergence in coconut
    (Department of Agricultural Botany, College of Horticulture, Vellanikkara, 1982) Balakrishnan, P C; KAU; Narayanan Namboodiri, K M
    A study was conducted at the Regional Agricultural Research Station, Pilicode and in the College of Horticulture, Vellanikkara during 1981-82 with the objectives of assessing the extent of variability present in the 24 cultivars of coconut maintained in the germplasm collection at Pilicode and to assess their genetic divergence using Mahalanobis D2 statistic. All the 24 cultivars were planted during 1924-25, and hence were of the same age group and were receiving the same management practices. Observations on 17 economic characters were recorded from 120 palms at the rate of 5 palms per cultivar. Four observations at quarterly intervals were recorded during the 12 month period of study. The data were subjected to relevant statistical analyses and the results were interpreted.
