This document describes a study on the variability of morphological and agronomic characters in 14 local and 6 introduced genotypes of bambara groundnut. The purpose is to determine differences in variability between local genotypes, introduced genotypes, and overall. The study uses a randomized block design with 20 genotypes and 3 replications. Data is analyzed using ANOVA and orthogonal contrasts to test hypotheses about differences in variability between groups. Observations are made on morphological and agronomic characters of the plant.

7. LAYOUT :
Randomized Block Design (RBD)
with a single factor (genotype),
which consists of 20 genotypes with
three replications, thus entirely
contains 60 experimental units.
Each genotype consists of 10
plants.
Analysis of data using Annova
(Analysis of Variance) and to
further test use orthogonal
contrasts.
Origin of genotypes:
•SS… = Sumedang (local)
•BBL…
= Lamongan (local)
•…B 1 = Bangkalan (local)
•Tv… = Thailand (introduction)
