Objective of the research were phenotypic and genetic correlation
coefficients of three species of Sorghum genus - forage sorghum S. bicolor
Moench. (genotype NS-Džin), Sudan grass S. sudanense L. (genotype Zora) and
interspecies hybrid S. bicolor x S. sudanense (genotype Siloking). Studies
were carried out on samples of plant material from the first cut. The
following morphological-productive traits were studied: plant height, number
of leaves per plant, mass of leaves on the stem, average stem mass and yield
of green biomass. In the analysis of genetic and phenotypic coefficients,
differences depending on the impact on studied morphological-productive
traits are observed. The highest value of the stem height was recorded in
Sudan grass (2.281 m), as well as number of leaves per plants (7.917). The
greatest mass of leaves per plant was established in forage sorghum (49.05
g), and the highest average stem mass was recorded in interspecies hybrid
plants (80.798 g). Variation of morphological-productive indicators per
species was significant and very significant. Coefficients of simple
correlations indicate the presence of very strong to almost complete,
statistically very significant positive correlations, so these effects were
expected. Plant height and number of leaves were not directly but indirectly
statistically significant to yield of green biomass and varied from
insignificant and very weak to sporadically medium strong and statistically
significant.
