Abstract
Description
The paper presents the analysis of single- and multi-dimensional
collection of sixteen genetic forms of lucerne (Medicago
sativa L. sl.) taking into account fifteen morphological characteristics.
Material for the study consisted of mutants of lucerne
inflorescence: paniculate, determinate, and elongate racemose.
In order to find relationships between the studied characteristics,
correlation analysis was used. There were significant correlations
between many phenotypic traits. Multivariate statistical analysis
was carried out: an analysis of variance with entries and years as
factors, followed by canonical variate analysis. A large genetic
diversity among the studied lucerne forms was found. Regression
analysis revealed that in different weather conditions in the
years of experiment other phenotypic features had an significant
impact on the mass of seeds of plants. Analysis of variance was
performed taking into account the type of mutation and a statistically
significant effect of mutations on the values of all fifteen
characteristics was observed in the experiment. When analysing
average values of individual traits for different types of mutations,
it was found that the highest seed weight occurred among
long-raceme mutants.
