Maize accessions were planted in Mtwapa and assessed for their morphological diversity. The results indicate that the maize accessions held at genebank are variable interms of kernel characteristics, plant height and days to maturity.
Mean length of 10 random ears from the point of attachment on the ear peducle to the tip of the dehusked ear.
Kernel rows per ear
Number of rows of kernel on 10 randomly selected ears.
Visual measurement whether the kernel colours are the same or not.
National accession number
A unique number representing each germplasm.
Mean height of 10 random plants, measured from the ground level to the tip of the head taken after flowering and before ripening.
Mean height of 10 random plant ears from the ground level to the node bearing the upper ear.
Days to 50% flowering
Number of days from planting to when 50% of the plants have extended silk.
Mid rib colour
Midrib colour of the third leaf counted from flag leaf downwards taken during or shortly after flowering.
Number of ears per plant
Average of 10 randomly selected plants from the middle of the plot.
Absence or prescence of pigments on leaf and stalk taken at seed filling stage.
